Beefs-up read speeds too
Here are the main numbers of this drive:
- 250GB, 500GB and 1TB capacities, using 3D NAND
- Random read and write IOPS – up to 500,000 and 400,000
- Sequential read and write bandwidth – up to 3,400 and 2,800MB/sec
- Endurance for 250GB, 500GB and 1TB capacities is 200, 300 and 600TB written
- Five-year limited warranty and 1.75m hours MTBF
WD said the improvements are due to fresh architecture and a better controller.
In comparison, Toshiba’s XD5 M.2 SSD has a much larger 1.9TB to 3.8TB capacity range but a slower 240,000/21,000 random read/write IOPS rating. Its sequential read and write bandwidth is slower too; 2,600MB/sec and 890MB/sec respectively.
This latest WD Black M.22 SSD is already available stateside in capacities of 250GB ($119.99 ), 500GB ($229.99) and 1TB ($449.99). It will be available by late April in select Western Digital retailers and distributors globally. ®
