ARCO Products are pretty good. I've used their first generation DupliDisk
controller for some time.
The only drawback with that version is that raid rebuilds must be done from
a DOS boot disk.
This has been fixed in the DupliDisk 2 product, it does background rebuilds
now, and they have a hot swappable drive enclosure as well.

That being said, the only reason I'm not using the IDE RAID is that I've
switched to Ultra160 SCSI RAID on my newer systems. I've used both the Dell
PERC and Mylex SCSI controllers, using RAID-1. IO performance is much better
on the SCSI drives. I've also blown more IDE drives than SCSI over the
years, especially on high load servers.
Thats my $0.02 anyhow :)
