Promise external IDE RAID storage with SCSI interface capable of 4 IDE drive each on their own controller (UltraTrak100) http://www.promise.com * expensive ($1500 or so) * onboard CPU (i dunno how fast this would make RAID5 on it) * hotswappable IDE interface (ie - user maintainable) this will be a production machine whose 24/7 reliability is critical. please reply off the list as well as i am not subscribed. i am mainly concerned with A) SPEED B) RELIABILITY/MAINTAINABILITY thank you.
