We have included the following press release on our SST software,
which was licensed by Western Digital Corporation for bundling
with the 7000-ASC controller on April 18, 1988.

WESTERN DIGITAL, COLUMBIA DATA PRODUCTS
ANNOUNCE FASST HARD DISK CONTROLLER BOARDS
IRVINE, CALIF., April 18, 1988 -- Western Digital Corporation
(AMEX:WDC) and Columbia Data Products, Inc. of Altamonte Springs,
Florida announced today the introduction of the FASST hard disk
and tape drive controller board family.
Designed specifically for IBM* PC AT* type systems, FASST
controller boards can achieve a host data transfer rate in excess
of five megabytes per second. This unparalleled rate is
accomplished using an innovative combination of parallel
processing techniques. A separate microprocessor, which resides
on the FASST controller, performs all data transfers by directly
communicating to the computer's memory via a process known as
"First Party DMA".
"The FASST product family is the bridge which brings mainframe
disk controller technology and performance to the desktop level,"
said Alan Welsh, President of Columbia Data Products. "Because
the FASST products are truly intelligent controllers, they
provide the revolutionary architecture for integrating all future
high performance peripherals while maintaining compatibility with
existing applications."
"This product is designed for applications which are disk
intensive, such as data base programs, computer aided design
(CAD) programs, Xenix or Unix systems and file servers," said
Kathy Braun, senior vice president and general manager of Western
Digital's Storage Products Strategic Business Unit.
The 7000-FASST, the initial product of the family, is a
combination of the 7000 series controller board from Western
Digital and the SST Software Package from Columbia Data Products.
Intended for use on an IBM PC AT or compatible with embedded SCSI
hard disk and tape drives, it is currently available from both
companies and their distributors.
Columbia Data Products, Inc., is a privately held developer and
supplier of ultra-high performance mass storage products and is
located in Altamonte Springs, Florida (407) 869-6700.
Western Digital Corporation, headquartered in Irvine, California,
with facilities worldwide, was founded in 1970 as a specialized
semiconductor manufacturer. Since then the company has become a
leading supplier of a broad range of storage management,
intelligent disk drive, communications, imaging and video
products for both OEM and end-user markets.

We have included the following information for you to help
explain what makes the new 7000-FASST, so fast! (Excuse the pun)

PARALLEL PROCESSING
Most of the existing hard drive controllers are not what you
would call intelligent. Your CPU has to tell it where to get the
data, wait for the drive to find the data, and then it has to
move one byte at a time from the controller to memory. Although
inefficient, this process can be speeded up by using a 20 Mhz
80386 CPU to move data. Thus a faster processor will give faster
data rates. Is this why mainframes have such fast drives? NO!
A mainframe CPU only issues a command for a specific chunk of
data and then goes on to another task. It has an INTELLIGENT
controller with its own CPU which figures out where to get the
data, waits for the data, actually moves the data into memory for
the CPU, and then notifies the CPU when it is done! Once the
command is issued by the CPU, it will take the same short amount
of time for an INTELLIGENT controller to put the requested data
in memory, no matter what the clock rate of the CPU! Thus a 1
Mhz CPU will have almost the same data throughput as a 40 Mhz
CPU--plus, both processors are working in parallel!
THIS IS WHAT WE HAVE DONE ON A DESKTOP!
This is only a small part of the beginning of the story of the
SST. If you would like to keep informed regarding our vision of a
MAINFRAME-ON-A-DESK, please call or write us at:
