We took note of the drive’s temperature during some of our benchmarking runs. The Kioxia Exceria Pro doesn't come with any form of a physical heat sink and did run very hot during some of our more extreme benchmark tests. It ran hottest when being pushed extremely hard during repeated runs of the CrystalDiskMark 8 test where the drive got to 72° C, rather too close to the 85° C drive maximum temperature for comfort. During the Performance Stability test, it peaked at 70° C. During these repeated tests there were signs that the drive was thermal throttling to some degree.
