Firstly sorry if this is in the wrong section and feel free to move to correct sub forum.
I'm looking at a 4 bay NAS and up until about an hour ago was going to go with raid 5 with 4 3tb WD Red drives. That was until I read that raid 5 is very unreliable on large drives.
I am wondering what the best options are, When I read about failures with raid 5 they were talking about large arrays like 36TB where as I'm only looking at a 12TB array obviously with parity I lose 1 drive so I get 9TB usable storage. What is the likeliness of a second drive failing on a rebuild? then there's the URE issue..
Am I just better going raid 10? but then what's the likeliness of a drive failing from the usable and mirror at the same time?
Advice much appreciated.
