Inside the box, The SSD is protected by a foam packaging to prevent any damage. The box also includes the warranty card. The SN750 measure 80 x 24.2 x 8.10 mm, with a weight of 33.2 grams including the heatsink.

In terms of design, the SN750 is very sleek and with its all-black PCB and aluminium heat-sink fins. It’s blends in nicely with the other components and feels great look at if you own a case with a glass side panel.

In our CrystalDiskMark benchmark, the WD Black SN750 nearly matches the speed advertised by WD and performs well with reading and writing operations.

CrystalDiskmark Read3,287 MB/s
CrystalDiskmark Write2,941 MB/s
ATTODisk Read3,260 MB/s
ATTODisk Write2,915MB/s
PCMark 8 Bandwidth Score548 MB/s

When copying files during everyday use, the speeds are in the range of 1500-2000 MB/s. The average bandwidth score during PCMark 8 tests were 554 MB/s.

In our Final Fantasy XIV StormBlood test, a benchmark that simulates game load time, the SN750 came out with an impressive load time of 11.55 seconds.

The SN750 maintained stable temperatures between 43-45 degrees during work tasks. And while gaming it went upto a maximum of 55 degrees, which is excellent for its class.


In additon to the standard options, the WD Black SSD Dashboard now includes a ‘gaming mode’. This new mode disables hardware-level power-saving features to reduce latency and increase performance. To enable gaming mode, you will need to restart your PC.

However, it didn’t seem to make any difference as we did not see a change during benchmarks. WD also includes Acronis True Image WD Edition which can be downloaded via the WD website.


The SN750 is one of the fastest SSD’s with a 3,400 MB/s read speed and 3000 MB /s write speed and claims to have a write durability of up to 600TB.

It was able to perform fast and smooth in our daily tasks and also significantly reduce loading times for the most resource-intensive games while remaining relatively cool.

Couple of the downsides here are the expensive price and lack of hardware encryption, which might be a deal-breaker for some. But when it comes to performance and aesthetics, the SN750 is one of our top recommendations.
