Acer FA100 vs Addlink S91: Comparison
Acer FA100 vs Addlink S91: the sequential read difference
The gap that matters here is sequential read: Acer FA100 3300 MB/s against Addlink S91 5000 MB/s, which puts Addlink S91 34% ahead. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 6, a 6% lead. Sequential write runs the same way, 2700 MB/s on the Acer FA100 versus 4000 MB/s on the Addlink S91, another win for Addlink S91. Nand layers runs the same way, 64 on the Acer FA100 versus 176 on the Addlink S91, another win for Addlink S91. There is a split on bus interface as well, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4 on the Addlink S91. They differ on nand type too, TLC on the Acer FA100 versus QLC on the Addlink S91. There is a split on dram cache as well, DRAM-less on the Acer FA100 versus DRAM-less with HMB on the Addlink S91. Form factor is not the same on both, M.2 2280 on the Acer FA100 versus M.2 2230 on the Addlink S91. They differ on controller too, IG5216 on the Acer FA100 versus Phison E21T on the Addlink S91. They differ on controller vendor too, InnoGrit on the Acer FA100 versus Phison on the Addlink S91.
Who each one is for
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 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, drive type and nand vendor included, so the decision does not turn on any of those.
