(old age is a terrible thing!) There is an IBM drive I saw advertised awhile ago which was wide scsi and had two HDA's acting as a single device. It did it's own head stripping and got upwards of 6Mb/s as I recall. The drives only spin at 5400rpm so data comes off each head at about 3Mb/s. When they make a new one with 7200rpm drives you might get close to 10Mb/s sustained. Tom
