Re: RAID definition

[DrFranken <midrange@xxxxxxxxxxxx>]

Only way that works if if they picked RAID 10.

But I know they picked RAID 10. ;-)

I don't like the way they described this though. They should have said 
"10 Drives with RAID-10 with 2 hot spares."  Since RAID-10 is mostly 
Mirroring, just done at the adapter level, 10 drives means 2 hot spares. 
In theory you could just get 9 and save a buck but have a bit less 
safety margin if a drive fails.
