Acer FA100 vs Kingston A400: Comparison
What is the difference between Acer FA100 and Kingston A400?
Sequential read is where these two genuinely part company, Acer FA100 3300 MB/s against Kingston A400 500 MB/s, a 85% lead for Acer FA100. Acer FA100 also leads on sequential write, 2700 MB/s on the Acer FA100 versus 450 MB/s on the Kingston A400. There is a split on bus interface as well, PCIe 3.0 x4 on the Acer FA100 versus SATA III on the Kingston A400. They differ on form factor too, M.2 2280 on the Acer FA100 versus 2.5-inch on the Kingston A400.
Which should you buy, Acer FA100 or Kingston A400?
The Acer FA100 suits everyday storage use where 3300 MB/s reads are fast enough. It is equally the pick for budget laptop or desktop upgrades wanting 2000 GB on a PCIe 3.0 x4 M.2 slot. Avoid it for buyers wanting PCIe 4.0 performance, as this drive is limited to 3300 MB/s reads. Take the Kingston A400 for buyers replacing an old mechanical hard drive who want the lowest-cost SATA SSD upgrade available. This drive delivers a dramatic real-world speed improvement at minimal cost. It is the wrong buy for buyers who want hardware encryption or top-tier SATA sustained performance. The Kingston KC600, covered elsewhere on this site, is the appropriate step up for those needs.
