                                I think my action plan now will be to figure out how to

                  (making it easy to
                  replace if need be), and then to play around with the

                  bit and see
                  how well it works.
                   
              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 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.

          Thanx, nate

          That's a good suggestion, but I think the USB memory sticks could
          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.

       Hi,

       (I apologize in advance if someone thinks this is OT)

       I've been reading this thread since it started, and what I could
       really say is you should go for freenas, it can be installed in
       a matter of minutes in a usb pendrive, I use it on a 2gb
       kingston one using an IBM eServer tower chassis, Intel D201GLY2
       mainboard, 1Gb 667Mhz RAM, 2 HDs those are 750gb SATA in RAID5


   2 drives in raid5? 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.
