SK hynix Platinum P41 1TB PCIe NVMe Gen4 M.2 2280 SSDLaptop upgraders and small-form-factor builders who want flagship speed without flagship heat.
For most buyers with an M.2 slot, the Samsung 990 PRO is the pick: the fastest Gen4 drive here with software that makes upgrading easy. Gamers should also consider the WD Black SN850X, value buyers should buy the Kingston NV3, and anyone on the smallest budget should buy the Kingston NV2. Machines without an M.2 slot should buy the Samsung 870 EVO instead, since SATA is the only route there.
The picks, ranked
Best overall
Samsung 990 PRO SSD 1TB PCIe 4.0 NVMe M.2
The flagship to beat: top Gen4 speeds, strong efficiency, and Samsung software that makes cloning and monitoring painless.
Strengths
- Sequential speeds up to 7,450 MB/s read and 6,900 MB/s write sit at the top of Gen4, so large games and video files move quickly.

The cheap Gen4 upgrade: 5,000 MB/s reads for little money, and a drive that makes any hard-drive machine feel new.
Strengths
- Reads up to 5,000 MB/s give a real Gen4 improvement over SATA for booting, apps, and games at a low cost.
- Capacity up to 4TB in the range means the same drive family can grow with a library, though this listing is 1TB.
- Crucial's cloning and support tools are approachable for first-time upgraders.
Limitations
- QLC NAND and no DRAM cache mean sustained writes slow more than on TLC DRAM drives when the drive is busy or nearly full.
- Endurance of 220 TBW at 1TB is the lowest here, so heavy professional writers should choose a higher-endurance drive.
- Write speeds trail reads by a wider margin than on flagship drives, which shows on large copies.
What owners report

Best cheapest upgrade
Kingston NV2 1TB M.2 2280 NVMe SSD PCIe 4.0 Gen4
The cheapest way into NVMe: modest Gen4 speeds that still leave hard drives and SATA far behind.
Strengths
- The lowest outlay here buys a genuine NVMe upgrade, with reads up to 3,500 MB/s that transform boot and load times.
- The compact M.2 2280 design fits most modern laptops and desktops with a spare NVMe slot.
- For everyday use, web, office, and light gaming, it feels nearly as quick as dearer drives despite the lower headline speed.
Limitations
- Write speeds up to 2,100 MB/s trail the rest of this list, so large file copies take noticeably longer.
- It is DRAM-less, so sustained writes and nearly-full use can slow it further.
- Endurance and warranty terms are modest, which suits everyday use rather than heavy professional workloads.
What owners report

| Sequential write | Up to 2,100 MB/s |
| Cache | DRAM-less, host memory buffer |
Best for: Anyone upgrading a hard-drive laptop or desktop on the smallest possible budget.
Skip if: You need high sustained write speed, or you plan to fill the drive close to full and keep writing heavily.
Best SATA upgrade
Samsung 870 EVO SATA III SSD 1TB 2.5 Inch
The SATA benchmark: the fastest a SATA bay can go, with Samsung reliability for machines without an M.2 slot.
Strengths
- Speeds up to 560 MB/s read and 530 MB/s write reach the practical limit of SATA, so no SATA drive here is meaningfully faster.
- Samsung Magician software and a long reliability record make it the low-risk SATA choice.
- The 2.5 inch form factor fits a huge range of older laptops and desktops, including machines NVMe cannot help.
Limitations
- SATA speeds are a fraction of NVMe speeds, so buyers with an M.2 slot should not buy SATA by habit.
- It needs a SATA cable and bay in a desktop, or a 2.5 inch slot in a laptop, which newer thin laptops may lack.
- Capacity per money lags behind value NVMe drives, since SATA is now a mature, slower technology.
What owners report
Commonly praised
- Older machines feel new again after the swap
- Samsung software makes cloning and monitoring simple
- Reliability over years gives owners real peace of mind
Common complaints
- Speed cannot match any NVMe drive in a machine with an M.2 slot

| Sequential write | Up to 530 MB/s |
| Endurance | 600 TBW, 5-year warranty |
Best for: Older laptops and desktops with a 2.5 inch bay and no spare M.2 slot, or as a second drive for a game library.
Skip if: Your machine has a free M.2 NVMe slot, where any NVMe here is several times faster for similar money.
Best small SATA upgrade
Crucial MX500 500GB 3D NAND SATA 2.5 Inch Internal SSD
The small SATA upgrade: 500GB of fast, reliable storage for a boot drive or a laptop that only needs a little more room.
Strengths
- Reads up to 560 MB/s match the SATA limit, so boot times and app launches improve as much as SATA allows.
- A DRAM cache, unusual at this level, keeps everyday performance steady when the drive fills up.
- The 500GB size suits a boot drive plus core apps, at a lower outlay than any 1TB drive here.
Limitations
- 500GB fills quickly with modern games, so game-library buyers should choose a 1TB drive instead.
- SATA speeds cannot match even the cheapest NVMe here, so M.2 owners should not choose it.
- Endurance of 180 TBW at 500GB suits everyday use rather than heavy write workloads.
What owners report
Commonly praised
- Boot times improve as much as SATA allows
- The DRAM cache keeps pace steady as the drive fills
- The small size makes a cheap boot-drive refresh easy to justify
Common complaints
- Games fill the space quickly and force careful management
- M.2 owners gain far more speed from any NVMe drive
- Endurance suits everyday use rather than heavy writing

| Endurance | 180 TBW, 5-year warranty |
Best for: Older machines that need a boot drive refresh, or a second SATA bay filled cheaply.
Skip if: You need 1TB or more, or your machine has an M.2 slot where NVMe is far faster.
How we chose
Interface first, speed second
A drive that does not fit is useless, however fast it claims to be. We sorted SATA and NVMe honestly, and only compared speeds within the same interface, so a SATA drive is never presented as competing with NVMe.
Speed where it matters
Headline sequential speeds matter for large files, but everyday feel comes from random performance and sustained behaviour. We credited DRAM caches and strong sustained write behaviour, and noted where DRAM-less and QLC designs slow down.
Endurance for the capacity
We recorded TBW for the exact capacity listed, since endurance scales with size. A 500GB drive is not judged against 1TB endurance figures, and heavy writers are steered to higher-endurance drives.
Honest value
A flagship that feels barely faster in daily use than a value drive is not automatically the best buy. We weighted the price step against the felt difference, which is why value Gen4 drives rank highly here.
Questions, answered
NVMe or SATA: which does my computer need?
Check for an M.2 slot that supports NVMe. If your machine has one free, buy NVMe, since it is several times faster than SATA for similar money. If it only has a 2.5 inch bay, buy SATA, and the 870 EVO or MX500 are the right choices.
Does Gen4 speed matter for everyday use?
Less than the jump from a hard drive to any SSD, which is the transformation that matters most. Beyond that, Gen4 speeds help most with large games, video files, and heavy multitasking, while web and office use feels similar across modern SSDs.
How much SSD capacity do I need?
500GB suits a boot drive with core apps, 1TB suits most users with a game or photo library, and 2TB suits large game libraries and video work. Buy 1TB if unsure, since modern games and projects fill 500GB faster than expected.
