The hyperStore 1600 Dual-Mode Caching Disk Controller features
state-of-the-art performance and compatibility with DOS,
Xenix/Unix, NetWare, OS/2, Pick, QNX, and other operating
systems. It works off an XT- or AT- slot with a 16-bit Z280
microprocessor and includes two I/O ports per card and a
dual-drive floppy controller for 5.25- and 3.5-inch drives.
 
Hard-disk performance enhancement is possible with 512K bytes of
cache memory expandable to 4 megabytes on the board and to a
total of 20 megabytes of cache with PSI's 16-megabyte expansion
card.
 
Data transfer is rated at more than 2.5 megabytes per second with
4 megabyte per second data bursts. Average data access is rated
at 0.28 milliseconds.
 
Each hyperStore works with PSI's Mediadapter for compatibility
with drives that need MFM, RLL, ESDI, or SCSI interfaces. The
hyperStore can support up to four Mediadapters per controller.
 
Price: $1195.
