WD has launched new consumer SSDs under its popular WD Green and WD Blue lines, as well as dramatically redesigned external hard drives. The announcements mark a change in direction for the company, acknowledging a shift in the purpose of traditional spinning hard drives and a preference among users for SSDs as their primary internal storage medium.
The new SSDs are aimed at PC users who have been moving away from hard drives when building and upgrading their PCs and laptops. In line with the existing hard drive product segmentation, the WD Green models are entry-level and tuned for lower power consumption, while the WD Blue products are suitable for more demanding users.
Both new SSD lines will be available as either standard 2.5-inch SATA drives or the newer M.2 format cards. However, the M.2 models also use SATA, not PCIe for connectivity, which confines speeds to the mainstream SSD class. Specifications are identical across form factors.
WD Green SSDs have launched in 120GB and 240GB capacities, with promised sequential read and write speeds of up to 540MBps and 405MBps respectively. Endurance is rated at 40TBW and 80TBW (terabytes written) over the life of each drive. WD Blue drives have launched in capacities of 250GB, 500GB and 1TB, and offer up to 545MBps and 525MBps sequential read and write speeds respectively, with endurance ranging from 100TBW to 400TBW depending on the capacity.
