The drive features TLC NAND flash memory and a WD 20-82-10048-A1 controller, but lacks a DRAM cache. Sequential read speeds reach 3500 MB/s and sequential write speeds up to 3000 MB/s. Random read performance is 423,769 IOPS and random write is 445,671 IOPS. The drive is rated for 600 total bytes written (TBW) and comes with a 5-year warranty. This SSD is suitable for use as a primary or secondary storage device in desktop and laptop computers that support M.2 NVMe drives. Its high sequential speeds benefit large file transfers and gaming loads, while the lack of DRAM is compensated by host memory buffer (HMB) technology.
