I believe that is essentially what I'm doing:

- 2 drive RAID0 using 500GB drives is 1TB
- 3 drive RAID1 using 500GB drives is 500GB

- 5 drive RAID6 using 500GB drives is 1.5TB

The RAID0 is moving to the RAID6
The RAID1 is moving to the RAID6

I'll purchase 1 additional 500GB drive to sit cold in my office in
case I drop a drive in the RAID6.

Sounds like it should work out well.

I'll investigate using a different drive for booting.

Thanks,
Mark
