WD Black SN750

Despite the appealing price and decent speeds, you’d be better off with a younger drive

The WD Black SN750 is a pensioner by SSD standards: it was launched back in 2019, as the firm’s flagship drive. That title has since been taken by the SN850, but the SN750 remains available.

It’s certainly a cheaper option. The 2TB model we tested works out at a very fair 15p per gigabyte, while the 1TB model can be had online for just £100 inc VAT, equivalent to 11p/GB.

While the Black SN750 is – like all SSDs of this vintage – limited to PCI Express

Gen3 connections, it delivers strong sequential speeds. Its read performance is the fastest we’ve seen from any Gen3 drive, while its write speeds are bested only by the Corsair MP400.

Sadly, when it comes to random-access operations, things collapse. Multithreaded performance is decidedly on the slow side, and for single-threaded operations AS SSD measured a glacial read rate of 24MB/sec, which is slower than any SATA model and behind even many USB drives.

That makes the SN750 a poor candidate for everyday use. The PCMark 10 benchmark suite gave it a score of just 1,266 in the system disk test, rising to a not much better 1,433 in the data drive test.

Like its stablemates, the WD Black SN750 comes with the WD-branded edition of Acronis True Image, and there’s a heatsink option for those who want to minimise thermal throttling. Whatever you do, though, you won’t be able to turn this drive into a contender: the price is alluring, but you’re better off paying a little extra for a more modern SSD.
