I'm looking for a 600 MB SCSI drive to replace my current 300 MB ESDI drive.
Two possible candidates are a CDC/Imprimis/Seagate ST4766N or a HP 97548.
I have enough information on the ST4766N drive but little on the HP drive.
According to an ad by a local distributor the HP should be a 20Mb/s drive
with an average access of 16ms. According to SCSICNTL the drive has 1457
cylinders with 16 heads and 57 sectors per track. This seems to indicate a
data transfer of slighly above 15 Mb/s. So is 20 Mb/s the real transfer rate
and if so why are there so little sectors per track.

Thanks in advance, Jean-Paul Smeets
