Overview :

A New Dimension Of Storage
Ready for your high performance computing needs, a WD Blue™ 3D NAND SATA SSD offers high capacity, enhanced reliability, and blazing speed.

High capacity with enhanced reliability
A WD Blue 3D NAND SATA SSD uses 3D NAND technology not only for higher capacities (up to 4TB in the 2.5″ 7mm form factor1) than the previous generation WD Blue SSDs, but also to help reduce cell-to-cell interference for enhanced reliability.

Superior Performance
3D NAND technology enables Sequential Read Speeds up to 560MB/s and Sequential Write Speeds up to 530MB/s.

Leading-Edge Reliability
An SSD is designed with no moving parts to help protect against data loss if it is accidentally bumped or dropped. And with 1.75M hours MTTF (mean time to failure)2, up to 600 TBW (terabytes written)3, and several error correction technologies, WD Blue 3D NAND SATA SSDs can help guard data for years to come.

Broad Compatibility
