About SSDs
Solid state drives listed by bus interface, form factor, NAND type, sequential read and write, endurance in terabytes written, and whether the drive ships with a heatsink.
Interface is the first filter. A PCIe 5.0 drive in a PCIe 3.0 slot runs at PCIe 3.0 speed, and an M.2 SATA drive will not work in a slot wired for NVMe only. SATA vs NVMe covers which one your machine can actually take, and motherboard M.2 slots at full speed explains why the second slot is often slower than the first.
331 drives in the catalog. Two things the spec sheet hides: sequential numbers are burst figures from the SLC cache, and they collapse on sustained writes once that cache fills, which SLC cache slowdown demonstrates. And some drives change controller or NAND mid-life under the same model name, which SSDs that change parts under the same name tracks.
For endurance read TBW explained. For the current market, the NAND shortage explains why prices moved, and PCIe 5.0 picks covers the top end.

How to choose an SSD
For almost everyone the drive is fast enough already. A PCIe 3.0 NVMe drive and a PCIe 5.0 drive feel identical opening applications and loading games, because those workloads are short random reads, not sustained transfers. Buy on endurance, sustained write behaviour and capacity, not on the headline sequential number.
The spec that actually varies: cache behaviour
Most consumer drives write fast into an SLC cache, then drop sharply once it fills. A drive quoting 7,000 MB/s may fall to 1,000 MB/s or lower partway through a large file copy. If you move big files, look for the post cache figure, not the peak.
DRAM or DRAM-less
DRAM-less drives are cheaper and fine as secondary storage. Under sustained mixed load, and on drives that are close to full, they slow down noticeably. For a boot drive that stays busy, a drive with its own DRAM is the safer buy.
Endurance and warranty
TBW tells you how much can be written before the warranty lapses. For normal desktop use even a low rating outlasts the machine. For video work, databases or a write heavy NAS, TBW is a real constraint and worth paying for.
Capacity and headroom
Drives slow down as they fill. Keeping roughly 15 to 20 percent free preserves write speed and gives the controller room to manage wear. Buy one size larger than you think you need rather than running a small drive at 95 percent.
Fit and heat
Check the form factor and length your board accepts, usually M.2 2280. PCIe 5.0 drives run hot and generally need the board's heatsink or their own. In a laptop, a tall aftermarket heatsink will not close.
Common mistakes
- Paying for PCIe 5.0 sequential speed for a gaming or office machine that will never use it.
- Putting an NVMe drive in a slot wired at PCIe 3.0 x2 and wondering why it is slow.
- Filling a QLC drive and judging it by the first, cached gigabyte.
FAQs
Will an M.2 2280 drive fit my laptop?
Only if the slot is 2280. Many compact laptops use the shorter 2242, and a 2280 drive physically will not fit. Check the service manual for your exact model.
Does a PCIe 5.0 drive work in a PCIe 4.0 slot?
Yes, at PCIe 4.0 speeds. It also runs hotter than a 4.0 drive would for the same result, which matters in a laptop.
What is DRAM cache and do I need it?
A dedicated memory buffer for the drive mapping table. DRAM-less drives are cheaper and fine for general use, but slow noticeably under sustained heavy writes.
What does TBW mean?
Terabytes written, the endurance the maker warrants. Normal desktop use rarely approaches it, so treat a low TBW as a warranty limit rather than a lifespan.
Is sequential read speed the number that matters?
Rarely. Random read performance and sustained write speed after the SLC cache fills affect everyday use far more than the headline sequential figure.
