That doesn't sound like thermal throttling. That sounds like you're running out of SLC cache space and writing at TLC speed, minus the overhead of the drive flushing the SLC cache in the background while you're still writing more data.
The solution is to get an enterprise drive, because they don't use SLC write caching and can usually sustain somewhat better write speeds as a result (plus, they're generally rated for more write endurance).
- AdrianB1 6y agoExcept that the transfer speed and drive temperature are linked together, we checked many times. If I do the same operation on 2 drives from 2 vendors and one works just fine and the other one shows 15 degrees C more on the same workload that almost fills and entire drive, what has SLC to do with this?
- wtallis 6y agoWithout knowing exactly what two drives you're comparing, I can't give you a clear answer. But it still sounds like you're deciding that the temperature is the cause of the performance difference, without having any evidence to rule out the possibility that the your temperature and performance observations are two different consequences of an underlying hardware difference between the two different drives.
