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.
