I agree with Tony that a RAID (not RAID Array - there's no such thing!) is unlikely to be found in a residential installation, with one caveat. The RAIDs that my company produces are becoming used in an increasingly large amount by people producing digital video. Most of these people either work out of their homes or they have shops in small offices located in residential areas.
The only good thing I can see from this situation is that they don't use RAID 3 or RAID 5 units. They prefer the speed they get from a RAID 0 system. Thus, we qualify our RAID 3/5 systems to class A (since they're used almost exclusively by banks, magazines, newspapers, and the sort), and our less complicated RAID 0 systems to class B for EMC. We qualify the safety of all of these systems to the various variations of the 950 standard, as required by the markets in which we sell. 60MHz systems can be problematic, especially if you're running single-ended SCSI. I hope you're not, since the 60MHz stuff has a lot of problems that are EMC and non-EMC related if you're single-ended. Are you running 60MHz interfaces on the disk drives, the RAID controller, and the host? If so, you have fewer problems than if you're mixing in fast SCSI with Ultra (should I have mentioned that word?). Well, good luck, Philip. Disk drive systems are such fun! Steve Chin FWB, Inc.
