ReadyNAS Pro Biz Edition upgrade from 6X2TB to ?
I have a 2009 ReadyNAS Pro Biz Edition that has six 2TB drives and it is running RAIDiator 4.2.22. I haven't had it on for awhile and quit using it because it filled up. I have a couple 3TB drives ...

Still not getting the math. at 14TB I already subtracted a full 4TB drive for redundancy. Then what is the additional 1.3TB being taken away?
14 TB and 12.7 TiB are the same amount of actual space, just reported using different units. Drive manufacturers always use TB. The NAS uses TiB, but calls it TB (as does Windows).
1 TB = 1000*1000*1000*1000 bytes
1 TiB = 1024*1024*1024*1024 bytes
To convert 14 TB to TiB, the formula is
14*(1000/1024)*(1000/1024)*(1000/1024)*(1000/1024) = 12.7 TiB.
There are similar mismatches for GB /GiB and MB/MiB.
So, vertical expansion.
Then yes. All the RAIDs must be resync before the last RAID1 is created.

Gotcha....it jumped from 16 hours to 3 hours, 21% to go, no drive failures yet. Will see what it says when done.
Thanks again to both of you!
