Acer FA100 vs ADATA Legend 900: Comparison
What is the difference between Acer FA100 and ADATA Legend 900?
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. Speed Score backs the spec sheet up. ADATA Legend 900 scores 6.6 to 6.4, 3% clear. ADATA Legend 900 also leads on sequential write, 2700 MB/s on the Acer FA100 versus 5400 MB/s on the ADATA Legend 900. Bus interface is not the same on both, 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. Nand layers runs the same way, 176 on the Acer FA100 versus 232 on the ADATA Legend 900, another win for ADATA Legend 900. There is a split on controller as well, IG5216 on the Acer FA100 versus SM2268XT2 on the ADATA Legend 900. They differ on controller vendor too, 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
The Acer FA100 suits everyday storage use where 3300 MB/s reads are fast enough. It is equally the pick for budget laptop or desktop upgrades wanting 2000 GB on a PCIe 3.0 x4 M.2 slot. Avoid it for buyers wanting PCIe 4.0 performance, as this drive is limited to 3300 MB/s reads.
What Acer FA100 and ADATA Legend 900 have in common
The common ground is wider than the gap: capacity, form factor and drive type are identical here.
