Does a cooler hard drive perform better?

Prithul0218 · May 23, 2019

Hi,
I was just wondering if a cooler hard disk perform better than a hotter one, or if a hard disk performs better in winter?

Here, by high temperature, I mean 45*-46*C which my HDD stays at during summer. and by a cold temperature I mean 8*-10*C .

No, hdds speed is deretmined by how many bits the head passes, and rpm and seek times doesn't change with tempature. Failure rate can increase with tempature, but 45 is normally fine.

HDD has specific temperatures it works best at. The speed stays the same, but failure rates differ massively. If 45c is the HDD temp not ambient then that is a good temp, if it is a normal hdd then over 50 is a bit iffy, but 45 is good. 30-40c is the ideal temp, but 20-50 is good, very minescule failure difference.

But if the HDD itself is 8-10c in the winter then that is bad for the HDD in the other direction, it is too cold.
