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 2TB1) than the previous generation WD Blue SSDs, but also to help reduce cell-to-cell interference for enhanced reliability.

Enhanced power efficiency

Offering improved endurance, a WD Blue 3D NAND SATA SSD features an active power draw up to 25% lower2 than previous generations of WD Blue SSDs. And with less power used, you’re able to work longer before recharging your laptop.

Superior performance for high-end computing

For high-end computing applications like gaming, HD media playback, or creative software, look to WD Blue 3D NAND SATA SSDs. 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 speeds3.

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)4, up to 500 TBW (terabytes written)5, 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.

3-year limited warranty

Every WD Blue 3D NAND SATA SSD comes with a 3-year limited warranty, so you can be confident of your storage when you upgrade or replace any of your drives.
