Addlink S91 vs Biwin M350: Comparison

Addlink S91 vs Biwin M350: the sequential write difference

On sequential write the spread is 17%, Addlink S91 4000 MB/s against Biwin M350 4800 MB/s, so Biwin M350 takes it. On sequential read there is little in it, 5000 MB/s on the Addlink S91 versus 5200 MB/s on the Biwin M350. Form factor is not the same on both, M.2 2230 on the Addlink S91 versus M.2 2280 on the Biwin M350. Biwin M350 also leads on nand layers, 176 on the Addlink S91 versus 232 on the Biwin M350. They differ on controller too, Phison E21T on the Addlink S91 versus SM2268XT2 on the Biwin M350. There is a split on controller vendor as well, Phison on the Addlink S91 versus Silicon Motion on the Biwin M350.

Where the two are identical

Where they agree, they agree completely, capacity, bus interface, nand type, dram cache and drive type included, so the decision does not turn on any of those. They match on 1 further specification as well.
