ADATA Technology is one of the world's leading manufacturers of high performance memory modules and data storage solutions. Founded in 2001 with a staff of 20, this Taiwanese company set itself apart from the competition early on thanks to its professionalism, industry know-how and eye-catching product designs.

Backed by technical expertise, state-of-the-art manufacturing facilities and premium customer service, ADATA currently offers a variety of products including DRAM modules, USB flash drives, memory cards, solid state drives and portable hard drives.

Earlier this year, ADATA launched its flagship 2.5-inch SATA SSD, the Ultimate SU900. Designed for use in everything from the lightest ultrabooks to high-end desktops, this performance-oriented drive is powered by Silicon Motion's SM2258 controller and is available with up to 2TB of 3D MLC NAND flash. The SU900 also utilizes intelligent SLC caching and a DRAM cache buffer to deliver up to 560 MB/s read and 525 MB/s write speeds. In addition, it features technologies like LDPC error correction, data shaping, wear leveling and a RAID Engine to provide high TBW and eliminate the vast majority of potential data errors.

The Ultimate SU800 is available in 256GB, 512GB, 1TB and 2TB capacities. For this review, ADATA sent us the 256GB version of the drive which is capable of delivering up to 560 MB/s sequential read and 520 MB/s sequential write speeds as well as up to 80,000 random read and 90,000 random write IOPS.
