Acer FA100 vs ADATA Legend 800: Comparison
Acer FA100 vs ADATA Legend 800: the sequential read difference
Sequential read is where these two genuinely part company, Acer FA100 3300 MB/s against ADATA Legend 800 3500 MB/s, a 6% lead for ADATA Legend 800. The sequential write figures are near enough to ignore, 2700 MB/s on the Acer FA100 versus 2800 MB/s on the ADATA Legend 800. 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 800. They differ on dram cache too, DRAM-less on the Acer FA100 versus DRAM-less with HMB on the ADATA Legend 800. Add nand layers to that, 176 on the Acer FA100 versus 128 on the ADATA Legend 800, and the pattern holds. Controller is not the same on both, IG5216 on the Acer FA100 versus IG5220 on the ADATA Legend 800. Nand vendor is not the same on both, Micron on the Acer FA100 versus YMTC on the ADATA Legend 800.
Who each one is for
Buy the Acer FA100 for 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. It is the wrong buy for buyers wanting PCIe 4.0 performance, as this drive is limited to 3300 MB/s reads.
What Acer FA100 and ADATA Legend 800 have in common
Where they agree, they agree completely, capacity, nand type, form factor, drive type and controller vendor included, so the decision does not turn on any of those.
