5TB raid

[teddy]

Need to make a 5TB raid.
I could go with a canned solution. But that would be no fun.

I was thinking about

One HighPoint RocketRAID 2322 PCI Express SATA II card (2 SAS connectors)
Two 4 bay SATA2 enclosures with hotswap drive.
EIGHT WD Caviar 1TB (Green) SATA drives not listed (Hitachi and Sumsung 
listed)

Setup the hw raid
Fill both 4 bay enclosures with four 1TB drives
Install Gentoo OS with RAID1 with two 80GB IDEs (basic OS only,/home 
/var etc. but NO DATA!)
(make a third copy if they request...raids do not prevent operator errors)
use IDEs as /dev/hda so the sata enclosures start with /dev/sda

After OS install is complete then attach the sata enclosures
and setup each as a RAID5 using mdadm, fstab at bootup

/dev/sda1 sda2 sda3  sda4=standby
/dev/sdb1 sdb2 sdb3 sdb4=standby

(you could probably get away with using seven 1TB drives, as long as you 
have email notification on a failed drive an replaced it immedialtely 
with the 7th drive)

/raid1=3TB RAID5 on enclosure1, mount as ext3 /raid1 via rc.local
/raid2=3TB RAID5 on enclosure2, mount as ext3 /raid2 via rc.local

Call HighPoint for advice first.
