Western Digital PC SN730 NVMe 256GB M.2 2280

This internal solid-state drive uses the M.2 2280 form factor and a PCIe Gen3 x4 interface. It provides 256GB of storage built with 3D NAND for consumer desktops and laptops. Sequential reads reach up to 3150 MBps and writes up to 2100 MBps.

PCIe Gen3 x4 NVMe v1.3 practical limits

The drive connects through a PCIe Gen3 x4 link using the NVMe v1.3 protocol. Peak throughput is bounded by the Gen3 lane rate, so sequential speeds top out at the rated 3150 MBps read and 2100 MBps write. Random performance scales to 270,000 read IOPS and 280,000 write IOPS. Endurance is rated up to 200 TBW with an MTTF of 1.75M hours.

Check your system before ordering

Verify the motherboard or laptop has an M.2 2280 slot wired for PCIe Gen3 x4 NVMe operation. The drive draws 30 mW idle and 100 mW active within a 0°C to 70°C operating range. Physical dimensions are 80.00mm long, 22.00mm wide and 2.38mm high.

Questions about this item

Should I choose the 256GB model or a larger capacity from the 256GB-1TB range?

The 256GB model suits light workloads and single-drive laptops; larger capacities up to 1TB provide more space and higher endurance for heavier write tasks.

What does the 3150 MBps sequential read figure mean once the drive is installed in my laptop?

It represents the peak throughput the controller can sustain over PCIe Gen3 x4; real-world speeds depend on the host controller, thermal limits and file sizes.

How does the PCIe Gen3 x4 NVMe v1.3 interface cap performance in practice?

The four-lane Gen3 link limits maximum theoretical bandwidth to roughly 4 GBps, so the drive's 3150 MBps read and 2100 MBps write sit within that ceiling.
