Acer FA100 vs Kingston A400: Comparison
Acer FA100 vs Kingston A400: the sequential read difference
Start with sequential read, because it is the widest measured gap between them: Acer FA100 3300 MB/s against Kingston A400 500 MB/s, 85% in favour of Acer FA100. Add sequential write to that, 2700 MB/s on the Acer FA100 versus 450 MB/s on the Kingston A400, and the pattern holds. Bus interface is not the same on both, PCIe 3.0 x4 on the Acer FA100 versus SATA III on the Kingston A400. There is a split on form factor as well, M.2 2280 on the Acer FA100 versus 2.5-inch on the Kingston A400.
Acer FA100 vs Kingston A400: which one fits your build
The Acer FA100 suits everyday laptops and desktops with a PCIe 3.0 M.2 slot. The same goes for budget upgrades needing 2000 GB of NVMe storage in a standard M.2 2280 slot. It is not the one for anyone wanting PCIe 4.0 speeds, since this drive tops out at 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. Avoid it 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.
What Acer FA100 and Kingston A400 have in common
Everything else lines up. Drive type read the same on both, so those are not worth weighing.

Which one should you pick?
Choose Acer FA100 if you want the higher sequential read (3300 MB/s vs 500 MB/s) and the higher sequential write (2700 MB/s vs 450 MB/s).
Choose Kingston A400 if you already have it on hand or find it at a lower price.
