1 TB PCIe Gen4 NVMe for compact PCs

The Western Digital WD PC SN740 delivers 1 TB of storage in an M.2 2230 form factor. Sequential reads reach 5150 MB/s and writes reach 4900 MB/s over a PCIe Gen4 x4 link. The drive is built for PCs and laptops that require a short 30 mm module.

Suits thin laptops and small-form-factor desktops

Devices with M.2 2230 slots can use this drive for fast boot, app loading and game storage. Systems that only accept longer M.2 modules cannot fit the 2230 length. Buyers needing higher capacity should consider larger drives.

M.2 2230 length decides compatibility

The 30 mm module length is the single specification that determines whether the drive fits. Check the device manual or motherboard layout for an M.2 2230 key before purchase.

Questions about this item

Will the WD PC SN740 1TB fit in a laptop that only has a standard M.2 2280 slot?

No, the WD PC SN740 uses the shorter M.2 2230 form factor, so it will not physically fit or secure properly in a standard M.2 2280 slot.

How can I confirm the drive is running at its rated 5150MB/s read speed after installation?

Run a sequential read benchmark such as CrystalDiskMark on an empty partition; a result near 5150 MB/s shows the PCIe Gen4 x4 link is active and the controller is performing to spec.

Does the WD PC SN740 1TB retail box include a heatsink or mounting screw?

The drive ships as a bare M.2 2230 module; any heatsink or M.2 mounting screw must be sourced separately from the laptop or motherboard accessory kit.
