Acer FA100 vs ADATA Legend 860: Comparison
What is the difference between Acer FA100 and ADATA Legend 860?
On sequential read the spread is 45%, Acer FA100 3300 MB/s against ADATA Legend 860 6000 MB/s, so ADATA Legend 860 takes it. Sequential write runs the same way, 2700 MB/s on the Acer FA100 versus 5000 MB/s on the ADATA Legend 860, another win for ADATA Legend 860. Bus interface is not the same on both, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4, M.2 2280 on the ADATA Legend 860. They differ on nand type too, TLC on the Acer FA100 versus QLC on the ADATA Legend 860. Controller is not the same on both, IG5216 on the Acer FA100 versus RTS5772DL on the ADATA Legend 860. They differ on nand vendor too, Micron on the Acer FA100 versus Micron 176-layer QLC on the ADATA Legend 860.
Which should you buy, Acer FA100 or ADATA Legend 860?
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. It is not the one for buyers wanting PCIe 4.0 performance, as this drive is limited to 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.
