Our take on the Western Digital PC SN730 256GB PCI-Express 3.0 x4 NVMe (v1.3) 3D-NAND TLC (SED) M.2 2280 Solid State Drive (SSD)

The WD PC SN730 is an OEM NVMe drive Western Digital built for laptop makers, sold here as a Lenovo pull. It is a PCIe 3.0 x4 M.2 2280 SSD with 3D TLC NAND and self-encrypting drive support. Sequential reads reach around 3,400 MB/s, so it feels quick for everyday Windows use and light creative work. Against current PCIe 4.0 drives it is a step behind on peak speed, but it runs cool and sips power, which suits thin laptops and small-form-factor builds. Buyers should confirm the slot takes NVMe, not SATA, and note that this is a used drive with no retail warranty.

Questions and answers

Will this fit my laptop?
It is an M.2 2280 drive, so it fits slots that accept that length. The slot must support NVMe over PCIe; a SATA-only M.2 slot will not work.
Is this drive new or used?
It is sold as a used Lenovo OEM pull that has been tested. Expect some prior use and check the drive's health after installing.
How fast is it compared with PCIe 4.0 drives?
It tops out around 3,400 MB/s sequential read on PCIe 3.0 x4. PCIe 4.0 drives are roughly twice as fast on paper, though everyday tasks feel similar.
Does it support hardware encryption?
Yes. The SN730 is a self-encrypting drive with OPAL support, usable with software that manages SED encryption.
What is in the box?
One WD PC SN730 256GB NVMe SSD. No screws, heatsink or cables are included.
Is 256GB enough?
For Windows, office apps and a few files, yes. For a game library or large video projects, a larger drive is a better fit.
