Acer FA100 vs ADATA Ultimate SU900: Comparison
What is the difference between Acer FA100 and ADATA Ultimate SU900?
Start with sequential read, because it is the widest measured gap between them: Acer FA100 3300 MB/s against ADATA Ultimate SU900 560 MB/s, 83% in favour of Acer FA100. Measured rather than claimed: in Speed Score the Acer FA100 returns 6.4 against 5.1, a 20% lead. Sequential write runs the same way, 2700 MB/s on the Acer FA100 versus 525 MB/s on the ADATA Ultimate SU900, another win for Acer FA100. Bus interface is not the same on both, PCIe 3.0 x4 on the Acer FA100 versus SATA 6 Gbps, 2.5" on the ADATA Ultimate SU900. There is a split on nand type as well, TLC on the Acer FA100 versus MLC on the ADATA Ultimate SU900. Dram cache is not the same on both, DRAM-less on the Acer FA100 versus 2048 MB on the ADATA Ultimate SU900. There is a split on form factor as well, M.2 2280 on the Acer FA100 versus 2.5-inch on the ADATA Ultimate SU900. They differ on controller too, IG5216 on the Acer FA100 versus SM2258H on the ADATA Ultimate SU900. Nand vendor is not the same on both, Micron on the Acer FA100 versus Micron 32-layer MLC on the ADATA Ultimate SU900.
Who each one is for
The Acer FA100 suits everyday laptops and desktops with a PCIe 3.0 M.2 slot. It is equally the pick 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.
What Acer FA100 and ADATA Ultimate SU900 have in common
