Solid State drive pricing keeps on getting lower and lower, but we still see 2.5-inch drives distinguished into three segments, entry-level, mainstream, and high performance. New entry-level drives more than likely do not have a DRAM chip for caching. That is the case with the Mushkin Source, which sits at the bottom of Mushkin’s solid state drive product stack. This drive is powered by the Silicon Motion SM2258XT controller teamed with Micron 3D TLC NAND. Mushkin tells us this combination boats sequential read and write speeds of 560 MB/s and 520 MB/s respectively. The 500GB version we are checking out today sells for only $89.99! Let’s jump in and see what it can do!
