I have a Pegasus R6 with 6 2-TD Drives in a Raid 10 setup. 10TB with a hot drive. This is connected to a MAC of the same vintage. Drives are from Aug-2011
Drive 3 failed: Hitachi HDS723020BLA642, 2TB drive.
Am I requited to replace this with the exact same drive or can I upgrade the drive from the Approved list on the PDF? Can I keep the other drives in the array 2TB and upgrade the one to 4TB with the intention of swapping in 4TB's in the future for the rest of the array?
I am not interested in pruchasing a new array at this time but would like to repair the one I have. I use this as an active backup, i.e. trust in the array as the backup for itself.
List of approved drives I would like to insert into the array
