November 28, 20223 yr Can UNRAID can recover data in a failed array as long as the Individual hard drives are not damaged or data corrupted ? Unlike losing 2 drives in a RAID5 array. Please let me know if this is the case. Also, Does it treat all the drives as if they all the smallest drive? So if you combined 8TB, 10TB, 12TB, 16TB, 20TB, etc.... Would all those drives be treated like 8TB drives or can it make use of the space in all those drives somehow? I think with RAID5, all the drives are all treated as 8TB drives since its the smallest. Thanks.
November 28, 20223 yr Community Expert Each data disk is an independent filesystem. There is no striping. Parity is a separate disk (or 2 disks for dual parity). This is how Unraid allows mixed size disks in the parity array. Each disk can be read all by itself on any linux. If more disks fail than can be recovered by parity, all remaining disks still have their contents.
