Is it better to leave your computer on all the time?
This is a general question about external hard disk drives (hard drive). Is it healthy for the drives to be connected all the time?
I own several brands (Seagate and Western Digital). I tend to unplug them if I'm not going to do any reading/writing for backups. But I'd like to know if I can keep them connected 24/7/365. I do notice that the light is on when they are connected, but are any discs spinning when it's in such a state? I somehow doubt it is unless it's explicitly being accessed by me or the computer.
I do keep my PCs and Macs running 24/7, and I'm not really concerned about the hard drive in them-- or maybe I should be?
Are there any real differences between the internal hard drives and external USB hard drives in terms of keeping them powered all the time? I somehow feel as though the internal hard drives, with the big fans, makes them safer to leave on all the time-- yet I don't know how to quantify it.
