Acer FA100 vs Lexar NM790: Comparison
Acer FA100 vs Lexar NM790 sequential read compared
On sequential read the spread is 55%, Acer FA100 3300 MB/s against Lexar NM790 7400 MB/s, so Lexar NM790 takes it. The benchmark result agrees. Speed Score puts Lexar NM790 17% ahead, 7.7 against 6.4. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 6500 MB/s on the Lexar NM790, and the pattern holds. They differ on bus interface too, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4, NVMe on the Lexar NM790. There is a split on nand type as well, TLC on the Acer FA100 versus TLC, DRAM-Less with Host Memory Buffer on the Lexar NM790.
Who each one is for
The Acer FA100 is the one to take for everyday laptops and desktops with a PCIe 3.0 M.2 slot. It also earns its place with budget upgrades needing 2000 GB of NVMe storage in a standard M.2 2280 slot. It is not the one for anyone wanting PCIe 4.0 speeds, since this drive tops out at 3300 MB/s reads. The Lexar NM790 suits budget-conscious gaming builds and PS5 storage expansion, though it is not built for sustained heavy write workloads and professional workstation use. Our rating of the Lexar NM790 (8.2/10): one of the best value flagship-speed drives available, though the DRAM-less design trades some sustained-write consistency.
