Acer FA100 vs Addlink S91: Comparison
Acer FA100 vs Addlink S91: the sequential read difference
On sequential read the spread is 34%, Acer FA100 3300 MB/s against Addlink S91 5000 MB/s, so Addlink S91 takes it. The benchmark result agrees. Speed Score puts Acer FA100 6% ahead, 6.4 against 6. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 4000 MB/s on the Addlink S91, 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 on the Addlink S91. Nand type is not the same on both, 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. Controller is not the same on both, 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.
Acer FA100 vs Addlink S91: which one fits your build
The Acer FA100 is the one to take 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 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
The common ground is wider than the gap: capacity, drive type, nand vendor and nand layers are identical here.
