The WD Blue SN580 series of drives is aimed at creative enthusiasts and professionals, but gamers and ordinary PC and laptop users may also like the novelties due to their low cost. The series includes drives from 250 GB to 2 TB.
For the most voluminous models of 1 and 2 TB, the manufacturer claims sequential read and write speeds of up to 4150 MB / s. For younger models of 250 and 512 GB, a read speed of 4000 MB / s is declared, and a write speed of 2000 and 2600 MB / s, respectively. Performance in random read operations for new products ranges from 240 thousand IOPS for the younger model and up to 600 thousand IOPS for older ones, and for random write operations – from 470 thousand to 750 thousand IOPS.
WD Blue SN580 drives feature nCache 4.0 technology with hybrid SLC cache to speed up large file transfers. In addition, SSDs are claimed to have low power consumption. According to the AnandTech portal, the WD Blue SN580 drives use 112-layer BiCS 5 3D TLC NAND flash memory chips, as well as a SanDisk 20-82-10082 quad-channel controller. The same combination of chips is used in the WD_Black SN770 SSD model. True, the firmware of the latter is optimized for gaming loads, and the WD Blue SN580 software focuses on workloads and lower power consumption.
