My 1TB drive is basically full (as is the backup of course) so I need to expand. I might finally get my act together and figure out this RAID thing (I have online backup with CrashPlan, so it's not ultra important to have this extra level of security.
But, what size of drive to buy? It's tempting to get 2 or 4TB drives so I don't have to deal with this again for a while, but I read somewhere that the larger ones simply have more disks (and readers and mechanics) in them, which adds a bit of possible failure chance. Or is it comparable to having four 1TB drives (with all their mechanics etc)?
I'd like to have at least 2TB (and the same as backup), should I go to 4? It's less of a price issue to me, more a reliability and clutter on my desk issue.
