after reading post from various scsi biggot i'll post my
experiences.

i had ide boxen for years,  until i built my first server =)
ended up being a dual pentium with scsi 3 x hdd +  2 x cdr + cdrw ...

i was more that surprised by system performance when i moved from
ide to scsi as the interupt load on the cpu when down by a factor of
ten ... thanks to command quing.

i could run a networked 25 player quake server *and* burn cds at 4X =)
after i moved to tulip network cards, and with samba do all those
things you do at a lan party type event =)

i had an adaptec 2940AU and later used tekram 390c(?) UW cards...

i would prefer the tekram, but the main performance issue was that
the hard disks max read was 6.5MB/s and write was only 5.5MB/s ...

so ... raid! and 9.99MB/s read and 8.99 MB/s write, on a aha 2940AU
i could run bonnie over 1GB files and burn cds at the same time ... =) 
not nice, but an interesting test. remember this is on a dual P133 
with only 128MB ram ... and a 33MHz PCI bus. so new systems should
be able to do much better.

scsi make sense for server boxes, but not really for desktop boxes,
IMHO...

yours,

kim
