ADATA SP550 M.2 2280

ADATA has re-launched the very affordable Premier SP550 SSD in a new M.2 2280 form factor, providing users with more options for low-cost SSD storage. Pricing for the Premier SP550 M.2 2280 starts at only $45.99 for the 120GB version. The 240GB and 480GB versions are also available for $69.99 and $129.99 respectively. The 2.5″ version of the Premier SP550 SATA SSD was previously reviewed here at Modders-Inc, sporting a Silicon Motion SM2256 controller paired with 16nm TLC NAND. The Premier SP550 makes use of intelligent SLC caching algorithm, allowing the TLC NAND to operate in simulated single-level cell mode, boosting read/write performance. Compared to some low-cost TLC options, the Premier SP550 has a DRAM cache buffer for improved performance which can be as much as twice that of ones without.
