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):

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

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 tons of 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.
