WD Blue 3D NAND 250GB SATA SSD
This 2.5 inch internal solid state drive uses 3D NAND flash and a SATA III interface. It is built for everyday consumer workloads such as operating system boot, application launch and general file storage.
SATA III 6Gb/s interface
The drive connects through a standard SATA III port, delivering sequential reads up to 550 MB/s and writes up to 525 MB/s. Random performance reaches 95,000 IOPS read and 81,000 IOPS write, with an MTTF rating of 1.75M hours and 100 TBW endurance.
Fits 2.5 inch bays with 7mm height
Low idle power of 56mW and DEVSLP down to 5-7mW reduce laptop battery drain. Active power peaks at 2,250mW during writes. WD F.I.T. Lab certification confirms broad system compatibility, and free downloadable software enables drive monitoring, cloning and backup.

What does the 550 MB/s sequential read figure mean for everyday use?
The 550 MB/s read speed is the SATA III interface limit. In a real machine you will see faster boot times, quicker application launches and snappier file copies compared with a mechanical hard drive, but the drive cannot exceed the SATA ceiling.
How does the SATA III interface affect the drive's performance ceiling?
SATA III caps the drive at 6 Gb/s, so the quoted 550 MB/s read and 525 MB/s write speeds are the practical maximum. No firmware update or system tweak can push throughput beyond that limit.
Will the 2.5-inch 7 mm form factor fit my laptop's drive bay?
The drive measures 2.5 inches with a 7 mm z-height, the standard size for most laptop and desktop bays. If your system uses a thinner 7 mm caddy or spacer, the drive will still mount securely.
