The short version
The NM1090 Pro is Lexar's PCIe 5.0 x4 drive, using a Silicon Motion SM2508 controller, LPDDR4X DRAM and Micron 232-layer TLC. Tom's Hardware lists the 2TB at 14,000 MB/s reads, 13,000 MB/s writes and 1,400 TBW. Its testing of the 4TB found good all-round performance and fair pricing for Gen5, but nothing that sets it apart. It suits enthusiasts wanting Gen5 speed. The double-sided layout may not fit every slim laptop.
Pros
- 14,000 MB/s reads and 13,000 MB/s writes listed at 2TB
- DRAM-equipped SM2508 controller
- 1,400 TBW and a five-year warranty
- Reasonably priced for PCIe 5.0
Cons
- No standout features in Tom's Hardware's view
- Double-sided layout can be a problem in some laptops
Best for
- PCIe 5.0 desktops on a tighter budget
- Large file transfers

Common questions
Is the NM1090 Pro a good value for PCIe 5.0?
Tom's Hardware listed its pricing as a strength for a Gen5 drive, though it also found no features that clearly set it apart from competitors.
Does it need a heatsink?
Most PCIe 5.0 drives need active or substantial passive cooling, so use a motherboard M.2 heatsink or a suitable aftermarket cooler.
