Acer FA100 vs ADATA Ultimate SU800: Comparison
Acer FA100 vs ADATA Ultimate SU800: the sequential read difference
On sequential read the spread is 83%, Acer FA100 3300 MB/s against ADATA Ultimate SU800 560 MB/s, so Acer FA100 takes it. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 5.1, a 20% lead. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 520 MB/s on the ADATA Ultimate SU800, and the pattern holds. There is a split on form factor as well, M.2 2280 on the Acer FA100 versus 2.5-inch on the ADATA Ultimate SU800. Controller is not the same on both, IG5216 on the Acer FA100 versus Silicon Motion SM2258 on the ADATA Ultimate SU800. Controller vendor is not the same on both, InnoGrit on the Acer FA100 versus Silicon Motion on the ADATA Ultimate SU800.
Which should you buy, Acer FA100 or ADATA Ultimate SU800?
The Acer FA100 is the one to take for everyday storage use where 3300 MB/s reads are fast enough. The same goes for 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 ADATA Ultimate SU800 for value-conscious buyers who want top-tier SATA performance with a long, established production track record. This drive delivers proven reliability at a competitive price. Avoid it for buyers who want the absolute lowest-cost SATA option available. The Silicon Power Ace A55 or Patriot Burst Elite, both covered elsewhere on this site, undercut this drive's price further.
