Acer FA100 vs ADATA Legend 900: Comparison
Acer FA100 vs ADATA Legend 900 sequential read compared
Start with sequential read, because it is the widest measured gap between them: Acer FA100 3300 MB/s against ADATA Legend 900 7000 MB/s, 53% in favour of ADATA Legend 900. The benchmark result agrees. Speed Score puts ADATA Legend 900 17% ahead, 7.7 against 6.4. ADATA Legend 900 also leads on sequential write, 2700 MB/s on the Acer FA100 versus 5400 MB/s on the ADATA Legend 900. ADATA Legend 900 also leads on nand layers, 64 on the Acer FA100 versus 232 on the ADATA Legend 900. They differ on bus interface too, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4 on the ADATA Legend 900. Dram cache is not the same on both, DRAM-less on the Acer FA100 versus DRAM-less with HMB on the ADATA Legend 900. There is a split on controller as well, IG5216 on the Acer FA100 versus MAP1602A on the ADATA Legend 900. They differ on controller vendor too, InnoGrit on the Acer FA100 versus Other on the ADATA Legend 900. Nand vendor is not the same on both, Micron on the Acer FA100 versus YMTC on the ADATA Legend 900.
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 is equally the pick for budget upgrades needing 2000 GB of NVMe storage in a standard M.2 2280 slot. It is the wrong buy for anyone wanting PCIe 4.0 speeds, since this drive tops out at 3300 MB/s reads.
What Acer FA100 and ADATA Legend 900 have in common
Where they agree, they agree completely, capacity, nand type, form factor and drive type included, so the decision does not turn on any of those.
