Acer FA100 vs ADATA Legend 900: Comparison
Acer FA100 vs ADATA Legend 900: the sequential read difference
Sequential read is where these two genuinely part company, Acer FA100 3300 MB/s against ADATA Legend 900 7000 MB/s, a 53% lead for ADATA Legend 900. Speed Score backs the spec sheet up. ADATA Legend 900 scores 6.6 to 6.4, 3% clear. Sequential write runs the same way, 2700 MB/s on the Acer FA100 versus 5400 MB/s on the ADATA Legend 900, another win for ADATA Legend 900. Add nand layers to that, 64 on the Acer FA100 versus 232 on the ADATA Legend 900, and the pattern holds. There is a split on bus interface as well, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4 on the ADATA Legend 900. There is a split on nand type as well, TLC on the Acer FA100 versus QLC on the ADATA Legend 900. They differ on dram cache too, DRAM-less on the Acer FA100 versus DRAM-less with HMB on the ADATA Legend 900. They differ on controller too, IG5216 on the Acer FA100 versus SM2268XT2 on the ADATA Legend 900. Controller vendor is not the same on both, InnoGrit on the Acer FA100 versus Silicon Motion 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.
Acer FA100 vs ADATA Legend 900: which one fits your build
Buy the Acer FA100 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 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
Everything else lines up. Capacity, form factor and drive type read the same on both, so those are not worth weighing.
