Recently got a 1TB MX500 which is excellent in terms of performance although the temperature behaviour is a little odd. I was just wondering if this is normal?
For instance, in the same location with the same ambient temperature the Crucial MX500 idles over 10C higher than a 1TB MX300. Idle is currently 38C on the MX500.
Using light loads (like an idle virtual machine) the MX500 will jump in temperature and fluctuate 38C-50C whereas the MX300 stays below 35C and is consistent.
Finally, under heavy write today the Crucial MX500 reached 65C in a well ventilated desktop. I did the exact same test on the MX300 where it peaked at 45C. Intrestingly the temperature gradually builds at a gentle pace on the MX300 and then 'hits a wall' but on the MX500 it aggressively shoots up and seemed to keep increasing until the write finished. I’m concerned that on a hot day it could push the MX500 over the 70C mark.
I have used a range of different SSDs from different manufacturers over the years but never really seen one (in 2.5" form factor) to run as hot as the Crucial or just have inconsistent temperatures.
I understand that the operating temperature of this SSD is 0-70C and technically it is within safe limits however compared to my other models it seems to be a bit toasty and erratic. Really I just wanted to ask if this is normal and what everyone else is seeing or if it's possible a thermal pad or something could be poorly aligned, loose or something.
Thanks in advance for your responses.

I can't comment on the drive personally but as you say, it's within spec. Like all modern performance electronics (CPU's GPU's etc) they throttle to cool down if they get too hot.
On paper, the MX500 uses a different controller to the MX300 so wouldn't really be comparable. It also uses 64 later NAND vs 32 and the increased desnity of electrical components is presumably hotter. The drive is also faster which, again, usually equates to more heat.
Hopefully someone else with both drives can comment.

Thanks for your response.
I also have a Samsung 860 EVO 1TB sitting here with me which shows a similar story to the MX300 with the temperatures. Idles significantly lower and light loads don't increase much over idle. Just seems more consistent.
I repeated the test on the MX500, 300 and 860 but the MX500 doesn't seem to hit that wall other drives do. The EVO for example topped out at 42C in a 32GB write about half way through then hovered there whereas the MX500 kept climbing until the write was over. Increasing the write makes it hotter whilst having no effect on the EVO.
I’ve also seen a review which stated that the MX500 1TB, outside of it’s case, reached a maximum of 50C on the controller in there heavy write test and they mentioned it would be likely for it to be cooler when in the enclosure, which initially sparked my interest in the temperatures.
Maybe I'm just overthinking it. I'm just concerned that routinely allowing it to reach high temperatures will be detrimental to it's lifespan and the erratic behaviour of the temperature isn't something I've usually seen on a SSD.
Although ironically I’m probably doing more harm writing to it worrying about the temperatures than the actual temperatures themselves
Thanks again for your reply.

I noticed the same:
MX500 1TB temps are significantly higher than my old MX300 750GB.
When I did a full test, the MX500 reached 70°C quite quickly in my notebook.
In order to complete the test, I opened the housing of the notebook and installed a fan close to the MX500.
Starting at ~500MBs, even though the temperature dropped to ~60° with the help of the fan, writespeeds dropped more and more until less than ~100MB/s.
Even in an 35°C environment the MX300 never exceeded 63°C, without a fan.
I really wonder how the MX500 will do in summer, as it reaches 70°C quickly in an 22°C room.
Time will tell.
What's the highest acceptable SSD temperature?

Its rated to run up to 70C. It won't take damage as a result of getting that hot because it will throttle its performance to cool - which is I guess what you saw.

I recently upgraded my laptop from a convential hard drive to a MX500 1 TB
I found the following.
-During the cloneing process it got very warm in the case I had it in so I took it out as the adaptor was not conneced to the case and it cooled down a lot.
- Now installed the computer feels just as warm on normal use as it did with the old hard drive.
- Battery now last an extra hour (instead of 1hr 30 it is now 2hrs 30) this surprised me as I just thought it would have given me pore than that
- The computer runs much faster now instead of taking a good 5 mins to boot up from scratch and be usable it now takes about 20secs.
Im assuming this is pretty standard with 1TB SSD's but I was a bit suprised with the heat thing. Fortunately I dont do heavy stuff with my computer just Surfing the internet banking and emails but I wondered what would happen to the temp if I was a gamer or something like that. Has Crucial made any statements about the temperature of their drives etc.

It's a high performance electrical component. It's going to generate heat when under constant load the same as any other component. The drives are rated to run up to 70C after which they will self throttle their performance to cool down.

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.
