Just checked out drive temperatures on the MX500 as at idle my drive is 38C, compared to a Kington SUV400 250Gb drive which at idle is 28C. Ran both disks through Crytal Mark to see how the operating temperature changed under the same conditions. Here are the results: Drive name: Test: Read Write Temperature Crucial MX500: Seq Q32T1 556.8MB/s 486.7MB/s 38C to 45C instant temp increase 4KiB Q8T8 273.9 255.6 45C to 47C write 4KiB Q32T1 148.3 110.3 45C 4KiB Q1T1 39.52 73.43 45C And the Kingston Drive Drive name: Test: Read Write Temperature Kingston SUV 400 250GB: Seq Q32T1 524.4MB/s 491.3MB/s 28C to 30C read, 32C write 4KiB Q8T8 285.5 254.1 30C read,32C write 4KiB Q32T1 162.0 95.13 30C read, 32C write 4KiB Q1T1 26.48 51.81 30C read & write The two drives have comparible speeds, although the Crucial outperformed the Kingston in 4 areas shown in red above. The increase in temperature I would suspect is simply down to the density of the transistors in the Crucial drive. In repeat testing of the Crucial drive, I could get the temperature above 47C with the fan turned off! Both the above drives are mounted separately (side by side), are cooled by the same fan and have no components beneath them. Interestngly, a Seagate barracuda that's mounted above these drives showed a constant temperature throughout testing of both drives and when subjected to the same test at 34C.
