Western Digital 500GB WD Blue 3D NAND Internal PC SSD – SATA III 6 Gb/s, 2.5″/7mm, Up to 560 MB/s – WDS500G2B0A

The Western Digital Blue 3D NAND SATA SSD utilizes 3D NAND technology for capacities up to 4TB with enhanced reliability. Featuring an active power draw up to 25% less than previous generations of Western Digital Blue SSDs, you’re ready to work longer before recharging your laptop, even as sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s give the speed you wish to have for your most demanding computing applications. Combined with the free. you’ll be able to hopefully upgrade your system to the Western Digital Blue 3D NAND SATA SSD. |As used for storage capacity, one terabyte (TB) = one trillion bytes. Total accessible capacity varies depending on operating environment. | Active power draws are up to 25% lower throughout sequential reads than previous generations of Western Digital Blue SSD at the 500GB capacity point. | As used for transfer rate or interface, megabyte per second (MB/s) = 1,000,000 bytes per second and gigabit per second (Gb/s) = one billion bits per second.

Make sure this fits by entering your model number.

Sequential read speeds up to 560MB/s and sequential write speeds up to 530MB/s. | As used for transfer rate or interface, megabyte per second (MB/s) = 1 million bytes per second and gigabit per second (Gb/s) = 1 billion bits per second
An industry leading 1.75M hours mean time to failure (MTTF) (1) and up to 600 terabytes written (TBW) (2) for enhanced reliability. | (1) MTTF = Mean Time To Failure based on internal testing the use of Telcordia stress part testing. (2) TBW (terabytes written) values calculated the use of JEDEC client workload (JESD219) and vary by product capacity
WD F.I.T. Lab certification for compatibility with quite a lot of computers.
