I Got more than 80MB/sec on a Ultra 320 10k RPM single SCSI hard drive
attached on a U320 controller....so YES, IDE is cheaper but still far
long from SCSI performance... And I even didn't try 15K rpm drives...
Moreover IDE raid is not sompliant to standard, so forget this
####...Everything which is not standard is not reliable... So I hope
you won't lose any video on your VT[3]...
