Acer FA300 vs Silicon Power XPOWER XS90: Comparison
Acer FA300 vs Silicon Power XPOWER XS90 sequential read compared
Start with sequential read, because it is the widest measured gap between them: Acer FA300 11000 MB/s against Silicon Power XPOWER XS90 14300 MB/s, 23% in favour of Silicon Power XPOWER XS90. Sequential write runs the same way, 10000 MB/s on the Acer FA300 versus 13400 MB/s on the Silicon Power XPOWER XS90, another win for Silicon Power XPOWER XS90. They differ on dram cache too, DRAM-less on the Acer FA300 versus LPDDR4 DRAM cache on the Silicon Power XPOWER XS90. Controller is not the same on both, SM2504XT on the Acer FA300 versus TSMC 6nm-process controller on the Silicon Power XPOWER XS90.
Acer FA300 vs Silicon Power XPOWER XS90: which one fits your build
Take the Silicon Power XPOWER XS90 for buyers who already have a motherboard or laptop with a built-in M.2 heatsink and want top-tier Gen5 speed without paying for a redundant one. It is equally the pick for content creators and AI/ML workstation builders who want DRAM-backed caching at the top of the Gen5 speed chart. Avoid it for buyers who need a confirmed TBW/endurance number before committing to a drive for heavy write workloads. Our rating of the Silicon Power XPOWER XS90 (7.2/10): strong headline speeds that land it firmly among the fastest Gen5 consumer drives on paper, but we're marking this down slightly from where the raw numbers alone would put it because pricing, TBW, and NAND type are all still unknown. Worth watching once it hits retail, not yet a slam-dunk recommendation.
Frequently asked questions
