We took note of the drive’s temperature during some of our benchmarking runs. Klevv's GENUINE G560 comes with a well-designed heatsink which together with enhanced thermal management (thermal throttling) works well. The hottest the drive got was when being pushed hard during some of the CrystalDiskMark 8's Write tests where it got to 61° C. There's no information about the drive operating temperature on the Klevv website but the Phison controller's upper operating limit is 70° C. For the bulk of our testing the drive averaged 49° C with the 4K focussed tests averaging 40° C.
