Fantastic transfers with the right cables. (980+ MB/s sustained, 1.6 GB/s burst with USB 3 gen 2 and 440+ MB/s sustained, 1.2 GB burst with USB 3 gen 1... all transfers are from a 970 Evo in a desktop and an SN550 in the enclosure) Drives run cool.

A bit pricey, but it's the ROG tax. Supplied cables are short (about 400 mm). I'm calling this a weakness since if you're using this drive on a desktop with no front Type C port (pretty much any case older than about 2 years), you will need to use a longer Type C cable to get the full speed of the drive. This may not be an issue with laptops, but it's easier to shorten a long cable with a velcro tie than it is to get to the back of even fairly recent desktops.

At first I was really disappointed with this enclosure. I initially tried it with two different drives (a Samsung 960 Pro 512 GB and a WD SN750 500GB) and was getting terrible performance. Read and write speeds around 40 MB/s. This was with two different cables I had at hand used for charging and simple phone syncs. Then I used the supplied cables and the enclosure came to life. A third longer cable I had was also good, since it was newer and of better specs. The moral is that not every Type C cable are equal, and if you want to or need to use a longer cable, make sure it's USB 3.2 gen 1 or 2 compatible.
