ADATA SP550 Series – The Lowest Priced SSDs Around

If you are looking for a low cost SSD for you system you have likely seen the ADATA Premier SP550 SSDs for sale online. The Premier SP550 is one of the lowest priced SSDs around and feature a Silicon Motion SM2256 controller and SK Hynix 16nm Triple-Level Cell (TLC) NAND. The ADATA SP550 series offers up to 560MB/s read and up to 510MB/s write speeds for sequential performance and the maximum random 4K Read/Write speeds would be up to 80,000 and 75,000 IOPS. Performance varies greatly depending on the capacity of the drive (120GB, 240GB, 480GB, or 960GB), but those are pretty respectable numbers for an ultra-value SSD that costs as little as $0.21 per GB.
