WD Black SN750 1TB NVMe SSD: features, specs and who it suits

The WD Black SN750 is an internal solid state drive for desktop PCs and gaming rigs. This model, WDS100T3X0C, offers 1TB of storage on a small M.2 2280 card that plugs straight into the motherboard. It replaces or supplements an older hard drive or SATA SSD, with the aim of shorter load times and snappier everyday use.

What NVMe and Gen3 PCIe mean

NVMe is a protocol designed for flash storage. Instead of squeezing data through the older SATA interface, an NVMe drive talks to the processor over PCI Express lanes, which typically gives much higher throughput and lower delays. Western Digital rates the SN750 at up to 3,470 MB/s and describes the interface as Gen3 PCIe.

"Gen3" refers to the generation of PCI Express the drive uses. Newer boards also offer Gen4 and Gen5 slots, which are faster, but a Gen3 drive works in them and simply runs at its own speed. Quoted speeds like this are normally sequential read figures measured under ideal conditions, so real-world file copies and game loads will vary with the rest of your system.

The M.2 2280 format

The name "2280" tells you the card is 22 mm wide and 80 mm long. The listing gives dimensions of about 3.1 x 0.9 x 0.1 inches, which matches. This is the most common size for desktop motherboards and many laptops. The drive has no heatsink, so it is thin and fits under the heatsinks many motherboards provide for their M.2 slots. Western Digital also notes that the non-heatsink version comes in capacities from 250GB to 4TB, so 1TB sits in the middle of the range.

3D NAND

The listing mentions 3D NAND, which stacks memory cells in layers rather than laying them out flat. In general, this lets manufacturers fit more capacity into a small chip and helps with endurance and efficiency.

The gaming mode dashboard

Western Digital highlights an exclusive WD Black SSD Dashboard with a gaming mode, which it says improves game performance. Dashboard-style tools from drive makers usually also show drive health and temperature and let you update firmware, though you should check Western Digital's current software page for exactly what this one offers on your operating system.

Who it suits

The brand positions the drive for enthusiasts building custom desktops or gaming rigs. It also suits anyone upgrading a PC that has a free M.2 slot and wants a large, quick boot and games drive. A 1TB capacity gives room for an operating system, several large games and working files.

What to check before you buy

• Slot type: the drive is NVMe only. The listing states it is not compatible with the SATA interface, so confirm your motherboard's M.2 slot supports NVMe and not just SATA M.2 drives.
• Length: make sure your board or laptop takes 2280 cards.
• Free slot and screw: some boards share M.2 lanes with SATA ports, so check the manual to see whether using a slot disables a port. Most boards supply the small mounting screw, but it is worth confirming.
• Heat: this is a non-heatsink model. If your board has no M.2 heatsink, consider your case airflow, especially under long, heavy writes.
• Operating system: check that the dashboard software supports the system you use.
• Data: back up your files before cloning or reinstalling, and follow the manufacturer's guidance for migrating data.
