“Western Digital has clearly put a lot of time and effort into their new WD_BLACK SN850 SSD. In an effort to deliver the full potential of next-gen PCIe Gen4 technology, everything, from the WD_BLACK G2 controller to the 96-layer BiCS 3D TLC NAND flash, has been developed in house. Needless to say, this effort has paid off in spades as the WD_BLACK SN850 is one of the fastest consumer SSDs currently available. The 1TB version of the drive screamed through our sequential transfer rate tests, reading at speeds as high as 7,071 MB/s and writing at more 5,300 MB/s. It also did very well in our random write tests, producing nearly 211,000 IOPS at low queue depths.”
