Acer FA100 vs Silicon Power XPOWER XS90: Comparison
Acer FA100 vs Silicon Power XPOWER XS90 sequential read compared
The gap that matters here is sequential read: Acer FA100 3300 MB/s against Silicon Power XPOWER XS90 14300 MB/s, which puts Silicon Power XPOWER XS90 77% ahead. Sequential write runs the same way, 2700 MB/s on the Acer FA100 versus 13400 MB/s on the Silicon Power XPOWER XS90, another win for Silicon Power XPOWER XS90.
Which should you buy, Acer FA100 or Silicon Power XPOWER XS90?
Buy the Acer FA100 for everyday storage use where 3300 MB/s reads are fast enough. It also earns its place with budget laptop or desktop upgrades wanting 2000 GB on a PCIe 3.0 x4 M.2 slot. It is the wrong buy for buyers wanting PCIe 4.0 performance, as this drive is limited to 3300 MB/s reads. 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. The same goes 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
Do the Acer FA100 and Silicon Power XPOWER XS90 differ on bus interface?
