It's been a long time since we?ve looked at a 2.5-inch SATA III SSD aimed at the consumer market, so we thought we?d mix up our storage content a little bit and do a review on one. Yes, SATA III SSDs feel like yesterday's news since we?ve been saturating the SATA III 6Gbps interface for years, but the form factor will still be around for many more years. The high-end storage drive market is squarely focused on M.2 PCIe NVMe drives, but those with older desktops that don't have an M.2 slot or are working with laptop that only takes 2.5? SATA drives you couldn't care less about those articles. If you have been looking for the ultimate 2.5-inch SATA III SSD you are in for a treat today as we will be looking at the ADATA SU900 Ultimate SSD that uses 3D MLC NAND Flash and the SMI 2258 4-channel controller.
