Our take on the Western Digital Blue SN5100 1TB PCIe Gen 4.0 NVMe M.2 2280 Internal SSD

The WD Blue SN5100 is a 1TB internal SSD in the M.2 2280 form factor, using a PCIe Gen 4.0 NVMe interface. It is a mainstream drive aimed at everyday storage: booting a system, holding applications and games, and moving large files. It fits laptops and desktops with an NVMe-capable M.2 slot, but not SATA-only M.2 slots. Against premium Gen 4 drives it trades peak speed for lower cost, and against older SATA drives it is far quicker in everyday use.

About the Western Digital Blue SN5100 1TB PCIe Gen 4.0 NVMe M.2 2280 Internal SSD

The WD Blue SN5100 is a 1TB internal solid state drive in an M.2 2280 module. It connects over PCI Express Gen 4.0 using the NVMe protocol, so it needs a host with an NVMe-capable M.2 slot.

It is meant for upgrading storage in a compatible laptop or desktop, for applications and everyday files. It is not a SATA M.2 drive and will not work in a SATA-only M.2 slot. It is also not a 2.5-inch SATA drive.

Before installing, check that the slot supports M.2 NVMe and accepts a 2280-length module, and that there is enough clearance. Also check the firmware and operating-system requirements and any system-specific mounting screw.

Questions and answers

Will it work in my laptop?
Only if the laptop has an M.2 slot that supports PCIe NVMe and accepts a 2280-length module. A SATA-only M.2 slot will not work with it.
Is it faster than a SATA SSD?
Yes. The NVMe PCIe Gen 4.0 interface moves data far faster than SATA, which shows most in large file transfers and game loading.
Does it come with a heatsink?
No. It is a bare M.2 2280 module, so a desktop or laptop that runs drives hot may need a separate heatsink or the board's own cover.
Do I need a mounting screw?
Often yes. Many drives ship without one, so check whether your system already has the screw and standoff in the M.2 slot.
Is 1TB enough for a system drive?
For most users yes: it holds the operating system, applications and a good number of games. Heavy video or game libraries may want more capacity.
Is it compatible with a PS5?
Sony requires a Gen 4 NVMe drive with a heatsink and certain speed minimums. This bare module has no heatsink, so check the requirements before using it there.
