Acer FA100 vs ADATA Legend 860: Comparison
Acer FA100 vs ADATA Legend 860: the sequential read difference
The gap that matters here is sequential read: Acer FA100 3300 MB/s against ADATA Legend 860 6000 MB/s, which puts ADATA Legend 860 45% ahead. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 5000 MB/s on the ADATA Legend 860, 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, M.2 2280 on the ADATA Legend 860. Nand type is not the same on both, TLC on the Acer FA100 versus QLC on the ADATA Legend 860. There is a split on controller as well, IG5216 on the Acer FA100 versus RTS5772DL on the ADATA Legend 860. Nand vendor is not the same on both, Micron on the Acer FA100 versus Micron 176-layer QLC on the ADATA Legend 860.
Who each one is for
The Acer FA100 suits 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 not the one for anyone wanting PCIe 4.0 speeds, since this drive tops out at 3300 MB/s reads.
Where the two are identical
Where they agree, they agree completely, capacity, form factor and drive type included, so the decision does not turn on any of those.
