Western Digital Blue 4TB 2.5" SATA SSD
The Western Digital Blue WDS400T2B0A is a 4TB internal solid state drive built in a 2.5-inch form factor. It uses 3D NAND technology and a SATA III interface to deliver sequential read speeds up to 560 MBps and sequential write speeds up to 530 MBps. The drive is rated for 600 TBW and an MTTF of 1.75M hours.
Suits laptops and desktops needing high-capacity
This drive fits any system with a 2.5-inch SATA bay, making it a direct upgrade for older laptops or desktops that lack PCIe slots. The low active power draw of 60 mW average and slumber power of 56 mW helps extend battery life in portable machines. Users who need the higher throughput of a PCIe interface should consider a different drive.
600 TBW endurance rating defines the write lifespan
The 600 terabytes written specification tells you how much data can be written to the drive over its warranty period. Combined with the 1.75M hour MTTF and 3D NAND construction, this figure lets you judge whether the drive meets the durability needs of your workload.

What SATA interface must my laptop or desktop have for the 2.5" WDS400T2B0A to connect?
The drive uses a standard SATA III interface, so any system with a 2.5" SATA data and power connector will accept it.
Will the 4TB Blue SSD work reliably in an older SATA II port?
Yes, the SATA III interface is backward compatible with SATA II ports, though sequential speeds will be limited to the older port's maximum.
How can I verify the drive is healthy after installation?
Download the free WD Dashboard software to monitor SMART attributes, remaining life based on the 600 TBW rating, and current operating temperature.
