As the title says.
Basically, I have two small home NASes, one that backs the other up.
Each has a bunch (5) of 2TB drives in RAID5.
I'd like to turn the backup NAS off, but I run daily syncing.
Therefore, is it better, from a hardware-longevity standpoint (primarily the hard drives), to power cycle a computer one a day, if it's off for at least 20 of those hours, or leave it on.
If it's not, at what point does it cross the threshold? Once every three days? Longer? Where is the threshold?
Note: I'm not interested in power savings, or other stuff, just what will let my hardware last as long as possible.
Also, I'm not sure if this should be SuperUser or ServerFault...
It's a home project, but they are basically servers.
