Acer Predator GM7000 vs Western Digital WD_BLACK SN770M: Comparison
Acer Predator GM7000 vs Western Digital WD_BLACK SN770M: the sequential read difference
On sequential read the spread is 30%, Acer Predator GM7000 7400 MB/s against Western Digital WD_BLACK SN770M 5150 MB/s, so Acer Predator GM7000 takes it. Speed Score backs the spec sheet up. Acer Predator GM7000 scores 8.4 to 7, 17% clear. Add sequential write to that, 6700 MB/s on the Acer Predator GM7000 versus 4850 MB/s on the Western Digital WD_BLACK SN770M, and the pattern holds. Form factor is not the same on both, M.2 2280 on the Acer Predator GM7000 versus M.2 2230 on the Western Digital WD_BLACK SN770M.

Who each one is for
Take the Acer Predator GM7000 for gamers already invested in Acer's Predator ecosystem who want a matching-branded storage upgrade. This drive delivers solid PS5-compatible performance under familiar branding. It is not the one for buyers with no particular brand preference seeking the single best price-to-performance ratio. Several similarly specced competitors covered elsewhere on this site are worth comparing on price alone. 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 the wrong buy 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.
