The WD Black SN750 1TB NVMe SSD is £87 for 1TB: good deal

One of the fastest PCIe 3.0 SSDs at a historic low price.

The WD Black SN750 is a super-fast PCIe 3.0 SSD - and the 1TB model is down to £87 at Amazon UK, a historic low price. That's a fantastic price for what was once among the fastest NVMe SSDs on the planet, with read speeds up to nearly 3500MB/s... before the advent of faster (and more expensive) PCIe 4.0 drives in the last couple of years.

Still, in terms of value for money, this TLC drive with a DRAM cache is going to be hard to beat - especially as the only real competitors tend to come with QLC NAND or without a DRAM cache, both of which sacrifice performance to hit lower price points!

Let's take a look at some competitors then. The SN750 costs £86.99 for a 1TB drive, so what else can we get for that kind of money on Amazon? The Crucial P2 is a great budget NVMe drive, but it's actually more expensive right now at £92.63. We could get the SN550 for £20 less, but this drive offers read speeds of around 2400MB/s - some 1100MB/s slower than the SN750. Based on this alone, I'd say the SN750 is worth the extra money, and that's before we look at writes - particularly sustained writes - where the SN550 is comparatively weaker.

What about going for a faster PCIe 4.0 drive - how much would we need to spend to get a significantly better drive? Right now, the WD SN850 is the best value option with a cost of around £133, with read speeds of 7000MB/s - so you get more or less a doubling of maximum performance for £46 more, or around 1.5 times the price of the SN750. This could be worthwhile if you're copying around massive files - think 4K video footage if you're a YouTuber, for instance - but you'll see smaller gains in other workloads thanks to the drives' relatively close random read and write speeds.

So overall then, I think the WD SN750 and SN850 are the best value options for most people - with the SN750 getting the nod for folks on PCIe 3.0 systems, while SN850 being a decent but not essential upgrade for those with motherboards that support PCIe 4.0.
