What sorts of cases are you using that allow for mounting 12 drives close
enough to the controller for all the cables to reach?
I was looking at a rack mount case today, that would let me put 23 drives
in a 7" high case.  All those cables should reach with standard 18"
cables.

About 450 bucks for the case, and around 900 for the adapters.
3ware has modified hardware that allows it to drive longer ide cables
( that exceed the 18" cable length )

3ware has a 8-port ide card ... for 8 master ide disks but its
still on one pci buss ( i think thats the bottle neck )

if you have 12, 26 ide disks... you'd need a 2nd pci slot...but again
on the one pci buss...

8 disks ( 160GB each ) is 1TeraByte of data that can be moving back and
forth on that pci buss...

i think it'd be better to put one ide controller ( like the 3-ware )
into one motherboard... and use a different server for the next 8 disks

-- am looking for benchmarks of 8-24-48 hard disks systems

we have 8-drive 1U chassis  - cabling is an issue... due to 18" maximum
but so far, we havent seen any major problems w/ the 24" and 26" length
cables..
