Further to this, I can get the Adaptec 2410SA at an affordable
price (it's around $500 AUD - roughly the cost of a 400GB HDD).
With that in mind, I'm leaning more towards a RAID1 setup
instead as I guess the extra cost for the controller gets rid of
the cost difference (not to mention the extra power consumption from
3 disks, heat, noise etc).
Am I crazy?
