I bought an MX500 500GB M.2 Sata SSD around a month ago.
This problem started right after putting it into my laptop (Acer E5-575G). What happened is that during cloning my old SSD to the MX500 using Acronis, a bit after starting the clone, and error would pop up saying something like "couldn't write sector" with an address of the sector. I didn't think much about it. Rebooted the PC so I would try it again. But the laptop wouldn't get past the Acer logo, meaning it couldn't POST. I rebooted a few times, then it worked. Then the Acronis clone was successful.
This problem didn't happen for a month after that, but I was a bit worried after this, since an SSD shouldn't do anything like this.
Then the problem happened again a week ago. More and more programs would freeze up, until the whole PC is frozen. Then usually it stays like that until I manually power off and turn it back on, or there is a BSOD saying CRITICAL_PROCESS_DIED or MEMORY_MANAGEMENT_ERROR. I assume these mean that Windows can't read certain sectors because the SSD crashes and is not visible to the system anymore.
Usually I have to wait 1 or 2 minutes before turning the laptop back on, because if I don't wait, the laptop would freeze during POST.
Sometimes after the SSD crashes, the I/O indicator LED is blinking, but sometimes the LED is off.
The SSD never recovers from this state. I have to manually turn the laptop off and on.
I have updated the firmware to the most recent one, M3CR023.
Here are SMART attributes:
The highest lifetime tempareatue was 88°C, which is quite high... although I don't know when that happened, because I have been monitoring it all the time and it never goes past 80 degrees. But usually when it is under load (updating game on Steam, copying files, etc.), it goes up to ~78°C rather quickly.
At first I thought the crashes happen because of the high temperatures. But I've read on multiple forums that the SSD should throttle its speeds in case of high temps. But mine crashes and I think this shouldn't happen even under heavy load.
I even installed a heatsink, and while the temps have lowered, the problem still happens. Never when the laptop is idle, only under load (update, file copy, etc.).
(Also, I think that temperatures like this are not normal for an M.2 SATA SSD. In laptops it's very hard to install an M.2 heatsink because of narrow space. I've not read anywhere that this SSD is meant for desktop PCs with proper ventillation, and not laptops.)
I think that this is a firmware bug or something. Is there a firmware update in the works?
I would have to return the SSD if this problem persists.
Also, there are sometimes events of Current Pending Sector Count changing to 1, but it always goes back to 0:
Edit: so after some hours of testing, it's clear that benchmarking programs such as HD Tune read test, HD Sentinel surface read test, AIDA64 read tests, AS SSD benchmark trigger the freeze/crash 100% of the time, regardless of temperatures. It doesn't matter if it's 45°C or 75°C, starting a read test in above programs triggers a freeze/crash of MX500 within 5 seconds. This was not always the case before. Maybe the SSD is starting to die or something.

FYI, Still waiting for the moderators to approve your screenshots.

The pending sector you have is going to be logical related, ie: something to do with the data/partition on the drive and how it interacts with the controller on the SSD, since there are 0 reallocated blocks on the drive.
Considering you had problems cloning, that probably means there were errors on your old drive which the software had difficulty reading, and the clone you did get to go through likely has errors as well.
You could try scheduling a check disk /r to see if that helps, otherwise it might be a good idea to simply perform a clean install of Windows to rule out any likely image problems. The temps you are getting are very high, but it's possible it's a result of the controller working overtime to try and make heads or tails of the errors it's trying to address (just a speculation).
I've also noticed your power cycles are high, your system is essentially cycling power to the drive once an hour which in itself should be fine, but it is odd. I would recommend disable idle drive power transition under the advanced power options to help with that.
- Go to Control Panel
- Go to Hardware and Sound
- Go to Power Options
- Select Change Plan Settings
- Select Change Advanced Settings
- Make sure the 'hard disk' field is set to ‘never’ (Laptop users select 'battery and power adapter').

First of all, thank you for responding.
Secondly, I have run chkdsk /r multiple times. It found problems on the filesystem, but after repairing those, it didn't help.
Also, I have formatted the SSD, installed a fresh Windows 10 on it, and it produced the same problem.
I ran the same benchmarks, and after a while, the SSD froze. The freeze happens when the SSD reaches around 85°C. This time it reached that temp in a longer time (maybe the room was colder or something), but it would crash everytime it reached around 85°C. I said before that these crashes are not connected to the temps, but now I think the two are connected.
The hard disk idle option in the power settings is set to never.
Also, yesterday I cloned back everything to my old SSD (in fear of the MX500 dying). There were a few unsuccessful tries, because the SSD would crash during the clone. It's only when I limited the transfer speed, the clone was successful. During this, I watched the temperature and it was around 78°C

@lajby95 those temps are way to high, the drive will actually shut itself off somewhere after 80C, so it's certainly doing that in some of your cases.
The freezing in POST however doesn't make sense, maybe the drive is still too hot and you aren't waiting long enough for it to cool down I suppose in those instances.
So thermal throttling should kick in at 70C. Realistically this means the drive shouldn't get above 70 that much, maybe it will hit 71 or 72, but the fact your drive is getting as hot as it is regularly is alarming. I know Acers have a reputation for heating up drives, but what you're getting is beyond even that.
Interestingly enough I'm looking at sales history for our MX500 M.2 drives on this system, and while not super extensive, we have quite a few purchases, and not a single return of any of the drives. So if it were a problem with these drives and this particular Acer, I should see a history of returns or replacements, but they simply don't exist.
Where did you purchase your drive from? If you bought it 3rd party I'd hate to say this, but it might be a good idea to simply return it for a refund before you get outside your return period. If you bought it from us we got the flexibility to refund even outside return period, so there is no deadline in this case. It's possible the drive itself is just defective, so there is certainly the option to setup an RMA, but if it's a 3rd party purchase from Amazon or Newegg setting up a replacement near the end of the return period could be running the chance of getting you outside that date if the replacement has issues as well.
You can setup a return or refund at the link below if you have your Crucial order number, also we can setup a replacement if you dindn't buy the drive from our website, just be sure to use the appropriate material number below when it asks for one.

Well, I ordered it from a shop in my country (Hungary), and here, the customer has the right to send it back without any reasoning during the 14-day period after purchase. Since I am way out of that period, I will try to send it back under warranty, and see where it goes from there. They may send it back to Crucial, or just give me another MX500. But if the new one is also overheating and freezing, they will probably give me a refund, or they let me choose a different product for the same price.
I will accept your answer as solution. Thank you for the help.
