I purchased a 7000 Diamond kit. It had a Hitachi CDR-7730 Quad Speed drive.
It said Rev A2 Type w Production date 6/95.
When I ran two deferent benchmark programs they both read at about 375kb,
nowhere near the 600kb transfer rate.
Do you have any info on this drive, I have not seen ANY advertisments on
this drive or any Hitachi CD-Rom.
