Capacity and form factor

The Western Digital SN740 provides 256 GB of storage in an M.2 2230 form factor. It connects through a PCIe Gen 4 x4 interface using the NVMe protocol. This drive suits ultra-thin laptops and compact devices that require the shorter 2230 length.

Sustained workload behaviour

The PCIe Gen 4 x4 link delivers high bandwidth for continuous read and write operations. NVMe command queuing keeps latency low when the drive handles prolonged file transfers or heavy application loads. Thermal throttling characteristics will depend on the cooling solution provided by the host device.

Compatibility checks

Verify that the motherboard or laptop has an M.2 slot keyed for PCIe NVMe and that it accepts the 2230 length. Confirm the system BIOS supports booting from an NVMe device. Ensure the operating system includes an NVMe driver or can load one during installation.

Questions about this item

Will this 256 GB M.2 2230 drive fit in my laptop or handheld?

It fits any slot that accepts an M.2 2230 NVMe module; check your device manual to confirm the slot length and keying before buying

Does my system need PCIe Gen 4 to use this SSD?

The drive runs on PCIe Gen 4 x4 but is backward compatible with Gen 3 slots; you will get Gen 3 speeds in that case

Is any extra hardware or cable required for installation?

No cables are needed; the drive plugs directly into the M.2 slot and is secured with a single screw supplied by the host device
