Featuring sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s giving you the speed you want for your most demanding computing applications**. Combined with the free, downloadable WD SSD Dashboard software and a 5-year limited warranty, you can confidently upgrade your system to the WD Blue 3D NAND SATA SSD.
High capacity with enhanced reliability
A WD Blue 3D NAND SATA SSD uses 3D NAND technology not only for higher capacities (up to 4TB*) than the previous generation WD Blue SATA SSDs, but also to help reduce cell-to-cell interference for enhanced reliability.
Superior performance for high-end computing
For a variety of computing applications like gaming, HD media playback, or creative software, look to WD Blue 3D NAND SATA SSDs. Western Digital™ 3D NAND technology helps enable sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s for fast system boot-ups, quick application responses, and rapid transfer speeds.**
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),*** up to 600 TBW (terabytes written),‡ and several error correction technologies, WD Blue 3D NAND SATA SSDs can help guard data for years to come.
Broad compatibility
With a certification from the WD Functional Integrity Testing Lab (F.I.T. Lab™), every WD Blue 3D NAND SATA SSD is verified for compatibility with a wide range of desktop and laptop computers. Every WD Blue 3D NAND SATA SSD goes through extensive compatibility and reliability testing to ensure it meets the high standards of the WD Brand.
Downloadable WD SSD Dashboard and Acronis software
Monitor your drive’s available capacity, operating temperatures, SMART attributes and more with the WD SSD Dashboard. Acronis® True Image™ WD Edition software, available as a free download, can clone drives and backup your operating system, applications, settings and all of your data.
5-year limited warrany‡‡
Every WD Blue 3D NAND SATA SSD comes with a 5-year limited warranty, so you can be confident of your storage when you upgrade or replace any of your drives.
*As used for storage capacity, one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment.
**As used for transfer rate or interface, megabyte per second (MB/s) = one million bytes per second and gigabit per second (Gb/s) = one billion bits per second.
***MTTF = Mean Time To Failure based on internal testing using Telcordia stress part testing.
‡TBW (terabytes written) values calculated using JEDEC client workload (JESD219) and vary by product capacity.
