Hi All,

I am trying to work out how much capacity is lost on a RAID 6 deployment within a backup solution I am looking at deploying (Datto).

7x 2TB disk at RAID 6 - how much useable space do I actually have?

thanks
Gareth

With RAID 6 you will lose the capacity of two of the drives.  In your case of 7 2T drives, you will have 10T total capacity (7-2)*2T.

Of course, these are nominal sizes and don't account for any overhead.
