I'm afraid that I may have quoted the Seagate model number wrong (my catalog
is at work).  

According to the UnixWorld quote (p136 "IPI in the Sky")

"... and currently supports Seagate Technology's Sabre parallel transfer disk.
With a storage capacity of 2105 megabytes, the Sabre product uses eight 
read/write heads simultaneously for transfer rates up to 24 megabytes 
per second. ..."

The catalog also lists a IPI-2 3GB disk drive with a transfer rate of 
27MB/second.
