Acer Predator GM7000 vs Addlink S91: Comparison
Acer Predator GM7000 vs Addlink S91: the sequential write difference
The gap that matters here is sequential write: Acer Predator GM7000 6700 MB/s against Addlink S91 4000 MB/s, which puts Acer Predator GM7000 40% ahead. Speed Score backs the spec sheet up. Acer Predator GM7000 scores 8.4 to 6, 29% clear. Add sequential read to that, 7400 MB/s on the Acer Predator GM7000 versus 5000 MB/s on the Addlink S91, and the pattern holds. Bus interface is not the same on both, PCIe 4.0 x4, NVMe on the Acer Predator GM7000 versus PCIe 4.0 x4 on the Addlink S91. They differ on nand type too, TLC with DRAM Cache on the Acer Predator GM7000 versus QLC on the Addlink S91. Dram cache is not the same on both, DRAM on the Acer Predator GM7000 versus DRAM-less with HMB on the Addlink S91. They differ on form factor too, M.2 2280 on the Acer Predator GM7000 versus M.2 2230 on the Addlink S91.
Which should you buy, Acer Predator GM7000 or Addlink S91?
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 the wrong buy 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.
Where the two are identical
Everything else lines up. Drive type and warranty read the same on both, so those are not worth weighing.
