Acer FA300 scores 8.5 to 7, 18% clear. Sequential write runs the same way, 10000 MB/s on the Acer FA300 versus 4900 MB/s on the Western Digital WD Black SN770, another win for Acer FA300. Bus interface is not the same on both, PCIe 5.0 x4 on the Acer FA300 versus PCIe 4.0 x4, NVMe on the Western Digital WD Black SN770.

Which should you buy, Acer FA300 or Western Digital WD Black SN770?
Take the Western Digital WD Black SN770 for mainstream desktop and laptop upgrades wanting strong Gen 4 speed without flagship pricing. The same goes 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.
