Samsung SSD PCIe 4.0 x4 NVMe M.2 2242
The 512GB PM991 pairs PCIe Gen 4 x4 NVMe with TLC NAND, delivering sequential reads up to 3100 MB/s and random reads up to 380K IOPS in a compact M.2 2242 form factor. Its 22 mm x 42 mm size fits 2242 slots directly and works in 2260 or 2280 with an adapter, while remaining backward compatible with PCIe Gen3 x4. This drive suits laptop and desktop users needing a small, low-profile storage upgrade for gaming or graphics-heavy workflows, though its portability score of 12.6/100 suggests it is not ideal for frequent external use.
