Acer FA100 vs Biwin M350: Comparison
Acer FA100 vs Biwin M350: the sequential write difference
Sequential write is where these two genuinely part company, Acer FA100 2700 MB/s against Biwin M350 4800 MB/s, a 44% lead for Biwin M350. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 6, a 6% lead. Add sequential read to that, 3300 MB/s on the Acer FA100 versus 5200 MB/s on the Biwin M350, and the pattern holds. Biwin M350 also leads on nand layers, 64 on the Acer FA100 versus 232 on the Biwin M350. There is a split on bus interface as well, PCIe 3.0 x4 on the Acer FA100 versus PCIe 4.0 x4 on the Biwin M350. There is a split on nand type as well, TLC on the Acer FA100 versus QLC on the Biwin M350. They differ on dram cache too, DRAM-less on the Acer FA100 versus DRAM-less with HMB on the Biwin M350. They differ on controller too, IG5216 on the Acer FA100 versus SM2268XT2 on the Biwin M350. Controller vendor is not the same on both, InnoGrit on the Acer FA100 versus Silicon Motion on the Biwin M350.
Which should you buy, Acer FA100 or Biwin M350?
The Acer FA100 suits 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 the wrong buy for anyone wanting PCIe 4.0 speeds, since this drive tops out at 3300 MB/s reads.
What Acer FA100 and Biwin M350 have in common
Everything else lines up. Capacity, form factor, drive type and nand vendor read the same on both, so those are not worth weighing.
