Ultra 160 SCSI / U2W compatability

[<andy@theasis.com>]

Shopping for a new SCSI drive has me a bit confused, since vendors have
multiple drives from the save vendor at pretty similar prices -- Only $20
difference between 7200 RPM U2W (DPSS-318350) and 10000 RPM Ultra 160
(DDVS-T18350) 18G IBM drives. I am intending to put this in a system that
has a U2W controller and 2 other U2W drives.

Can someone verify for me that Ultra 160 SCSI drives will fall back and
perform happily on an Ultra 2 wide controller? Of course I welcome any
additional comments on these drives in particular.

Thanks, 

Andy
