Come on. If you're going to post information like this at least do
some research **before** you post. Statements like this are just
plain misleading.
SCSI-2 is 8 bits wide, 10MB/second max transfer rate.
Ultra SCSI is 8 bits wide 20MB/second max transfer rate.
Ultra Wide SCSI is 16 bits wide, 40MB/second max transfer rate.
Newer SCSI-3 stuff is looking like upwards of 80MB/second transfer
rates. Then there is differential SCSI etc.
IDE is a good price/performance technology for average
workstations. Anyone that puts in a high performance server with
IDE drives, just plain doesn't know what they are doing or for some
reason or other is constrained by budget problems.
