physikal Posted March 23, 2018 Share Posted March 23, 2018 (edited) I have a 24 bay Supermicro box running unRAID. I have 2x 6TB Parity drives, 6x 6TB and 8x 4TB drives....with 8 more bays available....are 2x 6TB parity drives really going to cover a failure?

Key differences between unRaid and a classic raid is that if you ever exceed the number of simultaneous drive failures on classic raid you will have lost 100% of all your data. With unRaid you will only ever lose a portion.Additionally, with a classic raid solution a drive that takes a hair longer to respond to a read or write gets dropped from the array (TLER) and is thus a drive failure. Not so with unRaid. True drive failures are actually very rare Quote Link to comment
