WD Green SN350 1TB NVMe SSD: features, specs and who it suits

The WD Green SN350 is a 1TB internal solid state drive from Western Digital, model WDS100T3G0C. It uses the small M.2 2280 format and an NVMe connection. Western Digital positions it as a way to bring an older computer up to date for everyday use, such as study, shopping, chatting and browsing.

What NVMe and M.2 2280 mean

NVMe is a protocol for talking to storage over the PCIe bus, the same fast lane used by graphics cards. M.2 is the connector shape: a small flat card that plugs straight into the motherboard. "2280" refers to its size, 22 mm wide and 80 mm long. The listing gives the drive's dimensions as 3.1 x 0.9 x 0.1 inches (about 80 x 22 x 2.5 mm).

Not every M.2 slot accepts NVMe drives, since some only take SATA ones, so the slot's specification matters.

Speed: what "up to 3,200 MB/s" means

Western Digital rates the SN350 at up to 3,200 MB/s. That is a maximum under ideal conditions, and real-world speeds depend on the task, the computer and how full the drive is. The brand says it can work up to four times faster than SATA drives, which typically top out around 550 MB/s.

For daily use, the practical gain over a hard drive is large: quicker start-up, faster application launches and snappier file opening.

Gen3 PCIe and QLC

"Gen3 PCIe" means the drive works with the third-generation PCIe standard. It also runs in computers that have faster slots, but it won't use the extra bandwidth.

"QLC" describes the type of NAND flash, storing four bits per cell. QLC typically allows larger capacities at lower manufacturing complexity, though sustained heavy writing may be slower than with other flash types. Drives like this are generally aimed at everyday computing rather than constant large file transfers.

No moving parts

Because an SSD has no spinning platters, Western Digital says it offers a shock-resistant design that helps protect data against accidental bumps and drops. That matters most in laptops that are carried around.

Monitoring and warranty

The downloadable Western Digital SSD Dashboard lets you monitor the drive's health and usage. The drive comes with a three-year limited warranty from Western Digital, with terms that vary by region.

Who it suits

It suits people upgrading an older laptop or desktop from a hard drive, or adding fast storage to a computer with a free NVMe slot, for school, home or office work. Gamers or video editors who need the highest sustained speeds might look at faster drive types.

What to check before you buy

• Slot type: confirm that your computer's M.2 slot supports NVMe, not SATA only, and takes 2280-length drives.
• Clearance: some laptops have a heatsink or bracket that must be moved. Check the manual.
• Cloning or fresh install: decide whether you will copy your old drive across or install the operating system fresh.
• Software: the Dashboard is a separate download and works with Windows.
• Capacity: 1TB is the capacity for this model, so check what your files need.
• Static care: handle the drive by its edges.
