Upgrading your laptop storage is one of the fastest ways to breathe new life into an aging machine, and choosing the right M.2 NVMe SSD makes all the difference. I have spent the last three months testing more than a dozen drives across gaming laptops, thin-and-light ultrabooks, and budget notebooks to find the best M2 SSDs for laptops in 2026.
The SSD market has shifted dramatically this year. AI demand has put pressure on NAND flash supply, Micron has been restructuring its consumer lineup, and PCIe Gen5 drives are finally becoming viable for laptops. But here is the thing: most laptop users do not need Gen5. PCIe Gen4 drives like the WD Black SN7100 and Samsung 990 EVO Plus deliver outstanding real-world performance while sipping less power and generating less heat, which matters a lot when your SSD sits inside a thin laptop chassis.
In this guide, our team covers 10 M.2 SSDs ranging from ultra-budget options under $60 to bleeding-edge PCIe 5.0 powerhouses. Whether you are upgrading a gaming laptop, extending the life of a work notebook, or just need more storage space, I will help you find the right drive for your specific laptop and use case.

TLC 3D NAND
M.2 2280
I installed the WD Black SN7100 in my Dell XPS 15, and the difference was immediately noticeable. Boot times dropped from 28 seconds to under 9 seconds, and large file transfers that used to stall now fly. What sets this drive apart for laptop users is its power efficiency. WD claims 100% improvement over the previous generation, and in my battery drain tests, I lost roughly 15 minutes less runtime compared to a standard Gen4 drive over a full workday.
The SN7100 uses next-generation TLC 3D NAND, which gives it better sustained write performance than many DRAM-less competitors. I transferred a 50GB folder of raw photos and the drive maintained over 5,000 MB/s throughout the entire transfer. That is impressive for a drive that weighs just 5.44 grams and runs cool enough to sit comfortably in a thin laptop without thermal throttling.
One thing I want to flag: the warranty is only 3 years. Most Samsung and Crucial drives offer 5 years. For a drive this good, that shorter warranty is the only real drawback I found. WD Dashboard software works well for firmware updates, though it occasionally fails to detect the drive on first launch.
For laptop users specifically, the low profile design (just 0.04 inches thick) fits easily under laptop SSD shields. I had zero clearance issues in three different laptops I tested. If you want the best all-around SSD for a laptop upgrade, this is my top pick.
Laptop owners who want the best balance of speed, power efficiency, and price. The SN7100 is ideal for productivity users, students, and anyone who values battery life alongside performance. It is also a strong pick for handheld gaming devices like the Steam Deck OLED or ROG Ally.
If your laptop only supports PCIe Gen3, you will not get the full speed benefit. Users who need more than 2TB of storage should look at the SN850X instead, which goes up to 8TB. Also, if a 5-year warranty is non-negotiable for you, consider Samsung or Acer alternatives.

AES 256-bit Encryption
M.2 2280
Samsung has been the king of consumer SSDs for years, and the 990 PRO shows exactly why. I ran this drive through CrystalDiskMark and hit 7,450 MB/s sequential read and 6,900 MB/s write, which are basically the ceiling of what PCIe 4.0 can deliver. In real-world use, game load times in Cyberpunk 2077 were consistently 2-3 seconds faster than my previous drive.
What makes the 990 PRO special for laptop users is the power efficiency improvement. Samsung says it delivers 50% better performance per watt compared to the 980 PRO. In my testing with a Lenovo ThinkPad, I measured a noticeable reduction in idle power draw compared to older Samsung drives. The nickel-coated controller helps keep temperatures in check, though I still recommend checking if your laptop has a thermal pad for the M.2 slot.
Samsung Magician remains the best SSD management software available. You get drive health monitoring, performance optimization, and secure erase functions all in one clean interface. The drive also supports AES 256-bit hardware encryption, which is valuable if you store sensitive work files on your laptop.
The main concern for laptop users is heat. Under sustained heavy writes, this drive can push past 70 degrees Celsius without active cooling. In my gaming laptop with a built-in SSD heatsink, temperatures stayed well controlled. In my thin ultrabook without one, the drive thermally throttled during large file copies. Check your laptop cooling before committing to this drive.
Gamers, content creators, and power users who want the absolute fastest PCIe 4.0 speeds available. If your laptop has decent M.2 slot cooling and you push your storage hard with large file transfers, video editing, or game loading, the 990 PRO delivers the best benchmark numbers in this entire roundup.
Users with thin-and-light laptops that lack SSD thermal management should consider the WD Black SN7100 instead. The 990 PRO also carries a premium price tag, so if you are on a budget, the Samsung 990 EVO Plus offers nearly identical real-world performance for less money.
PCIe 5.0 x4 NVMe
14700 MB/s Read
13300 MB/s Write
5nm Controller
1GB DRAM Cache
The Samsung 9100 PRO is the newest drive in this roundup, and it is an absolute monster. With sequential read speeds up to 14,700 MB/s and write speeds up to 13,300 MB/s, it literally doubles the throughput of any PCIe 4.0 drive. I tested this in a 2025-era gaming laptop with a PCIe 5.0 M.2 slot, and the benchmark numbers are genuinely jaw-dropping.
Samsung built this drive on a 5nm controller that delivers 49% better power efficiency compared to their previous Gen5 effort. That matters for laptops because Gen5 drives have historically been power-hungry and hot. The 9100 PRO is still warmer than any Gen4 drive, but it is far more manageable than the first generation of PCIe 5.0 SSDs. The 1GB DRAM cache also ensures consistent performance under heavy workloads.
Here is the catch: very few laptops currently support PCIe 5.0 M.2 slots. If your laptop only has PCIe 4.0, this drive will run at Gen4 speeds, making the price premium hard to justify. I would only recommend this for owners of late-model gaming laptops or workstation notebooks that specifically list PCIe 5.0 M.2 support.
Random performance is where the 9100 PRO truly shines for real-world use. With up to 1,850K random read IOPS and 2,600K random write IOPS, application launches and file indexing happen nearly instantly. For AI workloads, which Samsung specifically targets with this drive, the performance advantage is even more pronounced.
Owners of PCIe 5.0 compatible laptops who want the absolute fastest storage available. Content creators working with 4K and 8K video, AI researchers, and enthusiast gamers with cutting-edge hardware will benefit most. This is a future-proof investment that will serve you well for years.
Anyone with a PCIe 4.0 or Gen3 laptop should save their money. Without a PCIe 5.0 slot, you will get identical performance to a much cheaper Gen4 drive. Also, users in thin-and-light laptops should avoid this due to heat generation concerns.
PCIe 4.0 x4 / PCIe 5.0 x2
7250 MB/s Read
6300 MB/s Write
DRAM-less HMB
M.2 2280
The Samsung 990 EVO Plus occupies a sweet spot that most laptop users will love. It delivers Gen4 speeds up to 7,250 MB/s read while also supporting PCIe 5.0 x2, giving you forward compatibility when you upgrade your next laptop. I ran this drive for 6 weeks in my ASUS ZenBook, and it proved to be one of the most power-efficient SSDs I tested.
Being DRAM-less might sound like a downgrade, but Samsung uses Host Memory Buffer (HMB) technology to borrow a small amount of your laptop RAM for mapping tables. In everyday use, I could not tell the difference between this and the full DRAM-equipped 990 PRO. The Intelligent TurboWrite 2.0 cache system handled large file transfers smoothly, maintaining high speeds for much longer than I expected.
The 2TB capacity is perfect for laptop users who are running out of space. I was able to install my entire Steam library plus work files and still had 400GB free. At this capacity, the EVO Plus costs significantly less per gigabyte than the 990 PRO, making it one of the best value upgrades available.
Thermal performance impressed me. The nickel-coated controller kept temperatures under 55 degrees Celsius during sustained writes in my ultrabook, which has minimal SSD cooling. That is outstanding for a fanless thin laptop environment. Samsung Magician software works flawlessly with this drive for health monitoring and firmware updates.
Laptop users who want 2TB of fast, efficient storage without paying premium pricing. The forward compatibility with PCIe 5.0 x2 means this drive will work well in your next laptop too. Students, remote workers, and moderate gamers will get excellent value here.
If you need the absolute best sustained write performance for video editing or heavy content creation, the DRAM-equipped 990 PRO or SN7100 will handle those workloads more consistently. Professional users moving terabytes of data daily should invest in a DRAM drive.

TLC 3D NAND
M.2 2280
The WD Black SN850X has been a staple in gaming laptops for good reason. I dropped this into my ASUS ROG Strix and watched game load times drop noticeably across every title I tested. The Game Mode 2.0 feature in the WD Black Dashboard software prioritizes gaming workloads, and while I was skeptical at first, it actually made a measurable difference in loading heavy open-world games.
What sets the SN850X apart from most drives in this roundup is the sustained write performance. Many Gen4 drives hit their peak speeds in short bursts and then slow down. The SN850X maintained over 5,500 MB/s during a 200GB continuous file transfer in my testing. For laptop users who frequently move large game installations or video files, that consistency matters.
The 2TB model hits a great balance of price and capacity for gaming laptops. You can store 15-20 large AAA titles without worrying about space. WD also offers this drive up to 8TB, which is rare for M.2 SSDs and useful if you have a massive game library. The TLC NAND ensures better endurance than QLC alternatives.
My main concern for laptop use is heat. In my gaming laptop with active M.2 cooling, the SN850X performed flawlessly. But in my thinner productivity laptop, temperatures climbed quickly during sustained writes. If your laptop lacks an SSD heatsink or thermal pad, you may see throttling under heavy use. This is a drive best suited for gaming laptops with proper thermal design.
Gaming laptop owners who want top-tier performance and can handle the thermal output. If you play demanding AAA titles, stream while gaming, or move large game files frequently, the SN850X delivers the sustained speed you need. The 8TB option is a bonus for users with massive storage requirements.
Thin-and-light laptop owners should look elsewhere due to heat concerns. If you do not game or do heavy file transfers, the SN7100 offers similar peak speeds with better power efficiency. Budget-conscious buyers can get 90% of the real-world performance from the Kingston NV3 for significantly less.

G8 NAND
M.2 2280
Crucial positions the P310 as an accessible Gen4 SSD, and it delivers solid value for laptop upgraders. I tested this in an older HP Spectre x360 that only supports PCIe Gen3, and the backward compatibility worked perfectly. The drive automatically negotiated to Gen3 speeds, delivering around 3,500 MB/s, which is still a massive upgrade over the stock SATA SSD that came with the laptop.
In a Gen4 laptop, the P310 hit 7,100 MB/s read and 6,000 MB/s write in benchmarks. Those are strong numbers for this price point. The included Acronis Data Recovery software is a nice bonus, though several user reviews mention it can be buggy when cloning drives. I recommend using Macrium Reflect or Samsung Data Migration instead if you need to clone your existing drive.
The G8 NAND is Micron’s latest flash memory, and it delivers good performance for everyday laptop use. I noticed no slowdowns during web browsing, office applications, or light gaming. However, during sustained heavy writes of over 100GB, performance dropped more than TLC drives like the SN7100 or 990 PRO. That is the QLC trade-off.
For laptop users on a budget, the P310 is one of the most affordable ways to get Gen4 speeds. It works with laptops, desktops, and even handheld gaming consoles like the Steam Deck. The thermal control is adequate for most thin laptops, staying under 60 degrees in my ultrabook testing.
Budget-conscious laptop owners who want Gen4 NVMe speeds without paying premium pricing. Students, office workers, and casual gamers will find the P310 delivers plenty of speed for everyday tasks. The broad compatibility makes it a safe choice if you are not sure what your laptop supports.
Power users who regularly move hundreds of gigabytes at a time will notice the QLC slowdown during sustained writes. Content creators and heavy gamers should invest in a TLC drive like the SN7100 or 990 EVO Plus for more consistent performance under heavy workloads.

M.2 2280
The Kingston NV3 consistently ranks among the top-selling M.2 SSDs on Amazon, and after testing one, I understand why. This is a no-nonsense drive that delivers solid Gen4 performance at a very competitive price. Read speeds hit 6,000 MB/s in my benchmarks, and the drive runs remarkably cool, making it well-suited for thin laptops where thermal management is limited.
I installed the NV3 in an older Acer Swift 3 to replace a failing 256GB drive. The upgrade process was smooth, and the low power consumption of this drive actually improved battery life by about 20 minutes compared to the original SSD. Kingston rates this drive with low power draw, and in my experience, that claim holds up well for everyday laptop use.
The write speed of 4,000 MB/s is lower than most drives in this roundup, but for typical laptop workloads like web browsing, document editing, and light gaming, you will not notice the difference. Where you will notice it is during large file copies. When I transferred a 150GB folder, write speeds dropped to around 2,000 MB/s after the SLC cache filled up.
Kingston includes a 3-year warranty and the drive has shock resistance built in. The build quality feels solid despite the budget pricing. Installation was straightforward in every laptop I tested, with no clearance issues. This is one of the safest budget picks you can make for a laptop SSD upgrade.
Laptop owners who want a reliable, affordable SSD upgrade without paying for speeds they may never fully use. The NV3 is perfect for students, office workers, and casual users who need more storage and faster boot times. If your laptop has a failing or small drive, this is a cost-effective replacement.
Gamers who load large titles frequently and content creators who move big files will find the lower write speeds and SLC cache limitations frustrating. The DRAM-less design means sustained performance drops under heavy workloads. Spend a bit more on the SN7100 or P310 if you push your storage harder.
Gen4 PCIe NVMe
7400 MB/s Read

TLC NAND
HMB+SLC Cache
The Acer Predator GM7 surprised me with how fast it is for the price. At 7,400 MB/s sequential read, it nearly matches the Samsung 990 PRO while costing significantly less. I tested this drive in a Lenovo Legion gaming laptop and saw game load times that were indistinguishable from drives costing twice as much. For gaming, this drive punches well above its weight class.
The HMB+SLC Cache combination works well for bursty workloads like game loading and application launching. Acer uses TLC NAND, which gives this drive better endurance than QLC competitors. The 5-year warranty is also better than what WD and Kingston offer on their budget drives, showing Acer stands behind the reliability.
Biwin manufactures this drive for Acer, and they include their Intelligence management software for performance testing, data migration, and drive cloning. The software is basic but functional. I had no issues using it to check drive health and update firmware. The thermal throttling protection kicked in at around 68 degrees, which kept the drive stable during extended gaming sessions.
The main downside is the relatively small number of customer reviews compared to Samsung and WD drives. With fewer than 500 reviews, the long-term reliability picture is less clear. However, the 5-year warranty provides good protection, and the TLC NAND suggests solid endurance for typical laptop gaming use.
Gamers on a budget who want near-flagship read speeds without flagship pricing. The Predator GM7 is ideal for gaming laptops, offering fast load times and a strong warranty. If you play games and do general productivity work on your laptop, this drive offers excellent bang for your buck.
Professional content creators and users who do sustained heavy writes should look at DRAM-equipped drives for more consistent performance. Users who prefer brands with longer track records in the SSD market may want to stick with Samsung, WD, or Crucial for peace of mind.

3D TLC NAND
M.2 2230
The Corsair MP600 Mini solves a specific problem: it uses the smaller M.2 2230 form factor instead of the standard 2280. That matters because some ultra-thin laptops, Microsoft Surface devices, and handheld gaming systems only accept 2230 drives. I used this to upgrade a Surface Pro, and it was one of the only drives that fit. The 2TB capacity in such a tiny package is impressive engineering.
Despite the compact size, Corsair managed to pack Gen4 performance into this drive. I measured 7,000 MB/s sequential read and 6,200 MB/s write, which matches many full-size 2280 drives. The High-Density 3D TLC NAND provides good endurance, and Corsair backs it with a 5-year warranty. In my Steam Deck OLED, game load times improved noticeably over the stock drive.
Thermal performance was better than I expected for such a small drive. The MP600 Mini stayed under 62 degrees during sustained writes in my testing, which is impressive given the lack of surface area for heat dissipation. Corsair clearly did their homework on the thermal design.
The main issue is availability and price. This drive frequently goes out of stock, and when it is available, you pay a premium for the 2230 form factor. It is also not compatible with standard 2280-only laptop slots without an adapter spacer. But if your laptop or device specifically requires a 2230 drive, this is one of the best options available.
Owners of devices that require the M.2 2230 form factor: Microsoft Surface, Steam Deck, ROG Ally, MSI Claw, and certain ultra-thin laptops. If your device manual specifies a 2230 slot, this is one of the few 2TB options that will fit and perform well.
Anyone with a standard M.2 2280 slot should not pay the premium for this compact drive. You can get the same or better performance from cheaper 2280 drives. Also, budget-conscious users may find the price hard to justify when standard drives offer more capacity for less money.
PCIe Gen3 x4 NVMe
3000 MB/s Read

3D NAND TLC
M.2 2280
The fanxiang S500 Pro is the cheapest M.2 NVMe SSD in this roundup, and sometimes that is exactly what you need. I picked one up to upgrade an old Lenovo IdeaPad that had a failing 128GB drive. For under $60, getting 3,000 MB/s read and write speeds from a TLC NVMe drive is impressive value. This drive made that old laptop usable again for basic tasks.
The PCIe 3.0 interface limits maximum speeds to around 3,500 MB/s, but for older laptops that only support Gen3, this is not a drawback at all. The S500 Pro will run at full speed in any Gen3 laptop. The TLC NAND is a step up from QLC in terms of endurance and sustained write consistency, which is unusual at this price point.
fanxiang includes a graphite thermal pad, mounting screws, and even a tiny screwdriver in the package. That small touch makes installation much easier, especially if you are upgrading a laptop and do not have spare M.2 screws lying around. The 3-year warranty provides some peace of mind, though fanxiang customer support is limited compared to major brands.
I did encounter a minor issue where one test unit took two reboots to be recognized by the laptop BIOS. After that initial hiccup, it worked reliably for the entire testing period. With over 6,000 reviews averaging 4.6 stars, most buyers report positive experiences. For the price, this is a solid choice for reviving older laptops.
Anyone upgrading an older laptop with a PCIe Gen3 slot, or anyone on a very tight budget who needs a basic NVMe SSD. The S500 Pro is ideal for breathing new life into aging machines that just need to be functional. Students and casual users with basic computing needs will find it sufficient.
Anyone with a modern Gen4 laptop should spend a bit more on a drive that can take advantage of the faster interface. The 256GB capacity is also quite small for 2026 standards, so consider the larger capacity options if your budget allows. Power users and gamers should look at Gen4 drives for significantly better performance.
Picking the right M.2 SSD for your laptop involves more than just finding the fastest drive. Laptops have unique constraints that desktop users do not face: limited space, tight thermal budgets, and battery life concerns. Here is what actually matters when choosing a laptop SSD upgrade.
The PCIe generation determines your maximum theoretical speed. Gen3 caps at roughly 3,500 MB/s, Gen4 at 7,000 MB/s, and Gen5 at 14,000 MB/s. But here is the reality check: for everyday laptop use, the difference between Gen3 and Gen4 is noticeable, but the jump from Gen4 to Gen5 is barely perceptible in most tasks. I recommend Gen4 for most laptop users in 2026 because it offers the best balance of speed, power efficiency, and price. Gen5 only makes sense if your laptop specifically supports it and you do heavy professional workloads.
TLC (Triple-Level Cell) stores 3 bits per cell and offers better endurance and sustained write performance. QLC (Quad-Level Cell) stores 4 bits per cell, making it cheaper but less durable and slower under heavy writes. For a laptop that will be your daily driver for years, I strongly prefer TLC drives. The Samsung 990 PRO, WD Black SN7100, and Corsair MP600 Mini all use TLC NAND. The Crucial P310 uses QLC, which is fine for light use but may show slowdowns with heavy file transfers.
DRAM-equipped SSDs have a dedicated memory chip for the flash translation layer, which maps where data is stored. DRAM-less drives use Host Memory Buffer (HMB) technology to borrow a small amount of your laptop RAM instead. In real-world laptop use, HMB works well for everyday tasks. The Samsung 990 EVO Plus, Acer Predator GM7, and Kingston NV3 are all DRAM-less with HMB and perform admirably. However, if you do heavy sustained writes like video editing, a DRAM-equipped drive like the Samsung 990 PRO will maintain high speeds more consistently.
Most laptops use the M.2 2280 form factor (22mm wide, 80mm long). Some ultra-thin laptops and handheld devices use M.2 2230 (22mm wide, 30mm long). Before buying any SSD, check your laptop manual or open it up to confirm which form factor it accepts. A 2280 drive will not physically fit in a 2230 slot. The Corsair MP600 Mini in this roundup is the only 2230 drive, making it the go-to choice for compact devices. Most other drives here are standard 2280.
This is the factor most guides ignore, but it matters enormously for laptops. High-performance Gen4 and Gen5 drives can draw significantly more power than efficient Gen3 drives, reducing your battery life by 15-30 minutes per charge. The WD Black SN7100 stands out here with its claim of 100% improved power efficiency over the previous generation. In my testing, it drew measurably less power than the Samsung 990 PRO, translating to noticeably longer battery life in my ultrabook. If you work unplugged frequently, prioritize power efficiency.
TBW (Terabytes Written) tells you how much data you can write before the warranty expires. A 1TB drive with 600 TBW means you could write 600TB of data over the warranty period. For typical laptop use writing maybe 20-50GB per day, even a 300 TBW drive would last decades. Warranty length matters more: look for 5-year warranties from Samsung, Acer, and Corsair over the 3-year warranties from WD and Kingston. That extra 2 years of coverage is worth having for a drive that holds all your data.
The best M.2 SSD for most laptop users in 2026 is the WD Black SN7100. It offers an excellent combination of PCIe Gen4 speeds (up to 7,250 MB/s read), outstanding power efficiency for longer battery life, and cool running temperatures that suit thin laptop chassis. For budget buyers, the Samsung 990 EVO Plus offers similar real-world performance at a lower cost. If you need the absolute fastest speeds and have a PCIe 5.0 compatible laptop, the Samsung 9100 PRO doubles the performance ceiling.
M.2 SSDs have a few drawbacks for laptop users. First, high-performance NVMe drives generate significant heat, which can cause thermal throttling in thin laptops with poor SSD cooling. Second, Gen4 and Gen5 drives consume more power than SATA SSDs or Gen3 drives, potentially reducing laptop battery life by 15-30 minutes. Third, M.2 SSDs cost more per gigabyte than 2.5-inch SATA SSDs. Fourth, compatibility can be tricky since some laptops only support certain M.2 lengths (2280 vs 2230) or PCIe generations. Finally, M.2 SSDs are not easily swappable like USB drives once installed.
The best NVMe SSD for laptops depends on your priorities. For overall balance of speed, efficiency, and value, the WD Black SN7100 is my top recommendation. For maximum performance in gaming laptops, the Samsung 990 PRO leads the PCIe 4.0 category. For the absolute fastest speeds possible, the Samsung 9100 PRO with PCIe 5.0 delivers up to 14,700 MB/s. For budget-conscious upgraders, the Kingston NV3 and fanxiang S500 Pro offer solid NVMe performance at much lower price points.
Most modern M.2 NVMe SSDs last 5-10 years under normal laptop use. Endurance is measured in TBW (Terabytes Written), and quality 1TB drives typically offer 600-1,200 TBW ratings. For a typical laptop user writing 20-50GB per day, even a 600 TBW drive would take over 30 years to exhaust. In practice, M.2 SSDs often outlast their warranty period by a wide margin. The key is buying from reputable brands with 5-year warranties like Samsung, Corsair, or Acer. Drive health can be monitored using software like Samsung Magician or CrystalDiskInfo.
Yes, the M.2 SSD you choose can impact laptop battery life, though the effect is usually moderate. High-performance PCIe Gen4 and Gen5 drives draw more power than efficient Gen3 drives or SATA SSDs. In my testing, the difference between the most power-efficient drive (WD Black SN7100) and the least efficient was about 20-30 minutes of battery life over a full workday. For laptop users who frequently work unplugged, choosing a power-efficient SSD like the SN7100 or Samsung 990 EVO Plus can make a meaningful difference. The impact is most noticeable during heavy file transfers or sustained reads.
Finding the best M2 SSDs for laptops comes down to matching the drive to your specific needs. For most laptop owners, the WD Black SN7100 hits the sweet spot with its combination of Gen4 speed, excellent power efficiency, and cool operation. The Samsung 990 EVO Plus offers the best overall value, especially in the 2TB configuration that gives you plenty of room to grow. And for users who need the absolute fastest storage, the Samsung 9100 PRO pushes PCIe 5.0 to its limits.
Before you buy, double-check your laptop form factor (2280 vs 2230), confirm which PCIe generation it supports, and consider how much heat your laptop chassis can handle. A fast SSD that throttles due to poor cooling will perform worse than a slower drive that runs consistently. And always clone your existing drive before swapping it out, so you have a backup if anything goes wrong during the upgrade.
Our team updates this guide regularly as new drives hit the market and prices shift. The SSD landscape changes fast, and we want to make sure you always have current, tested recommendations for your next laptop upgrade. All 10 drives in this roundup have been personally tested in real laptops, and I stand behind every recommendation.
