ADATA has introduced a new family of M.2 SSDs. The Premier SP550 SSDs utilize a Silicon Motion controller as well as TLC NAND flash memory, and retail at affordable prices. The ADATA Premier SP550 is powered by the Silicon Motion SM2256 controller as well as TLC NAND flash. The SM2256 controller supports error correction control and management technology based on low-density parity-check (LDPC) code to reduce data errors and increase data integrity. Besides, the SP550 drives use pseudo-SLC caching to ensure high writing performance as well as a dedicated DRAM cache.

The Premier SP550 SSDs are available in 120 GB, 240 GB and 480 GB configurations.

Featuring a SATA 6 Gb/s interface, the M.2-2280 offers performance in line with that of 2.5" SSDs based on the SMI SM2256 controller.

According to ADATA, you should expect read/write speeds of up to 560/510 MB/s as well as 4K random read at up to 75K IOPS.

The company has set the MSRPs of the M.2 Premier SP550 SSDs at $49.99 for 120 GB, $79.99 for 240 GB, and $119.99 for 480 GB version.
