I have also found that even a older (40Meg/sec aka Ultra wide) scsi
controller and drives can out perform even UDMA 100 when it comes to many
little reads and writes that you see in a busy mail server. I have been
tempted to try some of the new ide controllers (

eNumber=2 ) But if you have a working system I would not fault you at all
for letting sleeping dogs lie. =)
