WD's great value SN550 NVMe SSD is down to £175 for 2TB

An incredible amount of space, accessible at up to 2600MB/s.

The WD Blue SN550 is one of our favourite SSDs, and holds our current slot for the 'best budget NVMe SSD'. That's an important category too, as it offers a taste of the incredible speed offered by NVMe SSDs while costly just a fraction more than substantially slower SATA SSDs. Today, the largest capacity SN550 WD make, the 2TB model, is down to £175, around £50 cheaper than it's been for the last month and only a few pounds over an all-time low price.

If you're looking to add on a ton of super-fast storage for games and media, or even use this as the number one drive in a new system, this is a great value option that isn't lacking for performance.

Katharine's SN550 review calls the drive 'disgustingly good value', on the back of a low asking price and great sequential speeds. Compared to its already excellent predecessor, the SN550 improves its random write speeds as well as overall sustained importance, making it a much better choice to become your primary Windows drive.

As Katharine notes, while this drive is up to five times faster than a traditional 2.5-inch SATA drive, you'll need to have a motherboard with a free M.2 NVMe slot, or add one using a PCIe to NVMe SSD adapter. However, most motherboards - and even most laptops - these days come with at least one NVMe slot and often several, so the SN550 should be compatible with most computers built or bought in the last five years. If in doubt, search online for the name of your laptop and motherboard with the phrase "M.2 slot" in tow, and you should be good to go. Just remember that M.2 slots can support SATA drives, NVMe drives or both, so just confirm that you've got the NVMe sort before pulling the trigger.

If you're on the lookout for even faster speeds, why not check out our rundown of the best gaming SSDs? There are some lovely options here, including some PCIe 4.0 options that can reach up to 7000MB/s. That won't make too much of a difference in game load times, but the advent of Microsoft's DirectStorage API could change that in the future...
