The new quarter-rack Run-Length Limited Sabre Series 750 disk drive from Control Data Corp, stores 750Mb, has a seek time of 16mS or less, stores 19,816 bits per inch, has a transfer rate of 19.72Mbits per second – the Sabre 500 is comparable so upgrading is easy – and costs $4,260 without power supply; it replaces the older – and more expensive – 741Mb EMD drive, but that continues to be available: Sabre Series is the new name for the EMD family of 8 drives and they come with a choice of SMD-E or SCSI interfaces, with IPI-2 as well on the 750, which went on show for the first time at Siggraph in Anaheim, California late last month.
