Three new solid-state drives (SSDs) from Adata Technology expand the storage capacity over previous devices through the use of multi-level cell (MLC) NAND flash technology. The XPG SX900, part of the company’s Xtreme Performance Gear family of products, uses the SandForce 2281 controller. The drive offers 512 GB capacity with maximum sequential read and write speeds of 550/530 MB/s and maximum random 4k write speeds as high as 85,000 IOPS.
In addition, the Premier Pro SP900 features capacities of 64, 128, and 256 GB. Maximum sequential read and write speeds are 550/520 MB/s, with maximum random 4k write speeds similar to the SX900’s at 85,000 IOPS. Potential uses include upgrading notebooks that are compatible with the SATA 6 GB/s specification.
Lastly, the SATA II-compliant Premier SP800 serves as an entry-level SSD for users making the transition from mechanical drives. Offering capacities of 32 and 64 GB, the drive has read and write speeds of 280/260 MB/s and max random 4k write speeds of up to 44,000 IOPS.
