Launched without much fanfare or fuss, Crucial's BX500 is the company's latest addition to the entry-level BX series. To make the drive as competitive as possible in this cut-throat end of the market, the BX500 doesn't have a dedicated cache chip and has a thin plastic case.
The Crucial BX500 product line consists of three capacities; 120, 240 and 480GB and its the flagship 480GB drive we are looking at today. At the heart of the BX500 is a Silicon Motion SM2258XT four channel controller combined with Micron's 64-layer 3D TLC NAND and to keep costs at a minimum it's a DRAM-less design.
All three drives have the same Sequential performance figures; 540MB/s for reads and 500MB/s for writes although Crucial haven't disclosed any random read/write performance figures for the drive which is a bit odd.
The endurance rating for the drive is just 120TB TBW which works out at around 109GB a day for the length of the 3-year warranty Crucial back the drive with.
