Acer FA200 vs Western Digital WD_BLACK SN770M: Comparison
What is the difference between Acer FA200 and Western Digital WD_BLACK SN770M?
On sequential read the spread is 28%, Acer FA200 7200 MB/s against Western Digital WD_BLACK SN770M 5150 MB/s, so Acer FA200 takes it. Measured rather than claimed: in Speed Score the Western Digital WD_BLACK SN770M returns 7 against 6.6, a 6% lead. Sequential write runs the same way, 6200 MB/s on the Acer FA200 versus 4850 MB/s on the Western Digital WD_BLACK SN770M, another win for Acer FA200. Bus interface is not the same on both, PCIe 4.0 x4 on the Acer FA200 versus PCIe 4.0 x4, NVMe on the Western Digital WD_BLACK SN770M. They differ on nand type too, QLC on the Acer FA200 versus TLC, DRAMless on the Western Digital WD_BLACK SN770M. Dram cache is not the same on both, DRAM-less on the Acer FA200 versus DRAM-less with HMB on the Western Digital WD_BLACK SN770M. They differ on form factor too, M.2 2280 on the Acer FA200 versus M.2 2230 on the Western Digital WD_BLACK SN770M.
Who each one is for
Take the Acer FA200 for gamers and general users wanting 2000 GB of PCIe 4.0 storage at high read speeds. It is equally the pick for buyers who value a 5 year warranty and a 1000 TBW rating. Avoid it for workloads with constant heavy writing, since the NAND is QLC and the drive has no DRAM. Take the Western Digital WD_BLACK SN770M for handheld gaming PC and Steam Deck owners who want to upgrade or expand internal storage. This drive's compact 2230 form factor is purpose-built for that specific installation. It is not the one for standard desktop or laptop builds using the larger 2280 form factor. The WD Blue SN580, covered elsewhere on this site, fits that more common installation instead.
Where the two are identical
The common ground is wider than the gap: drive type and warranty are identical here.
