Which should you buy, Acer FA200 or Western Digital WD Black SN770?
Take the Acer FA200 for gamers and general users wanting 2000 GB of PCIe 4.0 storage at high read speeds. It also earns its place with buyers who value a 5 year warranty and a 1000 TBW rating. It is the wrong buy for workloads with constant heavy writing, since the NAND is QLC and the drive has no DRAM. Take the Western Digital WD Black SN770 for mainstream desktop and laptop upgrades wanting strong Gen 4 speed without flagship pricing. It is equally the pick for buyers who don't need a DRAM cache for their typical workload; HMB closes most of the practical gap. It is not the one for handheld or Steam Deck upgrades needing the smaller 2230 form factor. WD's own SN770M, covered elsewhere on this site, is built for that specific use case. Our rating of the Western Digital WD Black SN770 (8.4/10): one of the strongest mainstream value picks in the entire PCIe 4.0 tier.
