Another option you may want to consider is a PATA->CF adapter. I use these for my OpenBSD firewalls and have them installed on 1GB CF cards. Performance should be better? Compatibility certainly is better, there's no way I could boot to USB off these aging P3-800 systems. The CF cards just show up as regular HDs I use these ($7):http://www.geeks.com/details.asp?invtid=SY-ADIDE2CF-B1&cpc=SCH http://www.geeks.com/details.asp?invtid=SY-ADIDE2CF-B1&cpc=SCH

Paired with Lexar CF cards. Not all CF is created equal,well maybe it is today. I found my Lexar CF cards were 5-10x faster than my Kingston cards of the same size, which surprised me. Not that I need high performance in firewalls that do no disk I/O but it was painful for the OS install to take hours(Kingston) instead of minutes(Lexar). Both pairs of CF cards are a few years old, today maybe everything out there is reasonably fast.
At least with the above adapters be aware that those adapters above do stick up. I think a 2U chassis can fit them(I have tonsof experience in supermicro systems). But no guarantees. You may need another adapter or perhaps a male to female IDE cable so that you can mount it another way in the chassis.
I suppose you could even get two and run RAID. Just don't put your swap on the flash if you can avoid it. nate ______________________________________________ Thanx, nate That's a good suggestion, but I think the USB memory stickscould work better / more reliable, and will be easier to access in the cabinet. I'll play around with it a bit and see how it works.

Then it is really only a raid 0, and will fail sooner or later.
Even if it's fake RAID5(RAID software)? Didn't know that.
Raid 5 need a minimum of 3 drives. The only way to get 2 drives in software raid is to create the array with the "missing" statement. With only 2 drives, you have a stripe with a failed parity.
So 2 drives is already missing one, and the next failure is doom. Raid 1 (mirror) is fine with 2 drives.
Then I will have to backup ASAP and re install the Array in Raid1, thank you scott. But the odd thing its that I've never had any errors regarding RAID or even HDs. Will recheck my config.
