Capacity and interface

This is a 2.5 inch laptop internal hard drive with a 320GB capacity and a SATA 6.0Gb/s interface. It spins at 7200 RPM and includes a 16MB cache buffer. The drive is supplied as a bare unit with a 9.5mm z-height.

Suitable upgrades and limits

The drive suits users replacing a failed 2.5 inch SATA disk in an older laptop or adding a second drive where a caddy is available. It is not for systems that only accept M.2 or PCIe storage modules. It is also not for buyers who need more capacity than 320GB.

Deciding specification

The SATA 6.0Gb/s interface is the single specification that decides compatibility. The host must provide a standard 2.5 inch SATA bay and a matching data cable. Without that connection the drive cannot be used.

Questions about this item

How can I verify the WD3200BEKX is running at 7200 RPM after installation?

Use a tool such as CrystalDiskInfo or the BIOS drive information screen to confirm the rotational speed shows 7200 RPM and the SATA link reports 6.0 Gb/s.

What does the bare drive packaging include and what must I supply myself?

The box contains only the 2.5" 9.5 mm drive; you must provide mounting screws, a SATA data cable and a SATA power connection from the laptop.

Which capacity from the WD Black 2.5" line should I pick for a primary laptop drive?

The 320 GB model (WD3200BEKX) delivers 7200 RPM and 16 MB cache; select it when you need that performance level in a single drive.
