640 GB 3.5" SATA desktop drive

The Western Digital Blue WD6400AAKS is a 3.5-inch internal hard drive with a 640 GB capacity. It spins at 7200 RPM and provides a 16 MB cache over a SATA 3.0 Gb/s interface. The drive is supplied new and suits desktop PCs or compatible enclosures.

Check SATA port and 3.5" bay

Verify that your motherboard or controller has a free SATA port and that the chassis offers a 3.5-inch drive bay with mounting points. Confirm the power supply includes a SATA power connector for the drive. No adapter is needed when both connections are present.

Suits storage upgrades and replacements

This drive fits users adding bulk storage to a desktop or replacing an older mechanical disk. It is not for systems that only accept 2.5-inch drives or M.2 modules. Builders needing faster access speeds or a laptop form factor should consider other options.
