Western Digital's latest SSD with QLC technology boasts better performance in both reads and writes than its TLC-based predecessor (via ComputerBase). The company's newest SN5000S drive, despite using generally slow QLC NAND flash, is 16.5% faster in reads and 15.5% faster in writes compared to the TLC-based SN740.
The PC SN5000S is Western Digital's latest mainstream consumer SSD, available in the M.2 2280 "gumstick" and the small PC-compatible M.2 2230 form factors, with up to 2TB of storage. It essentially replaces the PC SN740 series, which is offered in the same capacities and form factors.
