"feel" depends mainly on whether you're busmastering or not.

ultra2 scsi is wonderful. it's also expensive. so much so that people
who buy it sometimes feel obliged to stretch the truth about ide.
yes, you can easily achieve 2:10 on a modern ide system (udma).

basically, modern ide disks sustain >20 MB/s.
most modern scsi do better, up to around 40 MB/s.
ide channels cost around $15 apiece.
ide disks are at around $8/GB (verus ~$30/GB for scsi)
