I can tell you from my experiences the new IDE drives are fast. I have a SCSI 80
stripped (8 37 GB IBM UW drives) set on a high end scsi card with 128MB cache
and I have a 3ware IDE strip set (4 40GB maxtor 7200 RPM drives). The IDE array is
over twice as fast as the scsi. My next rebuild would be the 8 port 3ware card and 8
IBM 72GB drives. 3Ware is claiming 100 MB/sec transfer rates and I don't doubt it.
My 4 port maxtor setup does ~40 MB/sec with the linux "hdpram -t /dev/sda"
command.
