Hi,
Until the new Quantum/Seagate/IBM Ultra drives are released, the current 
ultra drives available are standard drives fitted with ultra interface. 
You can make a slow drive Ultra compliant - Ultra means nothing but the 
SCSI bus spec., same as SCSI-II etc. The Quant Atlas II drives are 
faster because of their mechanics, not because of the "ultr" business. 
They use MR heads which result in greater data density on fewer platters 
to achieve faster sustained read/write capability. The Ultra means that 
they can feed into a Ultra spec "pipe", nothing more.
For single drive systems, it appears that Ultra offers no performance 
advantage. Ultra is supposed to be cheaper than wide, in time <g>.
