    Arco Announces New IDE Backup Device
  DupliDisk RAIDcase Makes Drive Mirroring 
            Easier Than Ever                  

HOLLYWOOD, Florida --Arco Computer Products, Inc.,
www.arcoide.com, a leading provider of low cost IDE disk
mirroring hardware, today announced the
DupliDisk RAIDcase, a real-time backup device that offers
PC users a simple and convenient way to maintain an exact,
up-to-the-minute duplicate of their IDE hard drives.

Despite the widespread use of IDE disk drives, disk
mirroring--writing data to two drives simultaneously--has
been implemented almost exclusively with SCSI hardware.
The complexity and high cost of SCSI systems has made
mirroring (also known as RAID 1) impractical for most
individual and small business users and even for many large
companies.
                         
With the DupliDisk RAIDcase, virtually any PC user can now
have the security of a redundant drive that can take over
instantly in the event of a disk crash. The RAIDcase is the
latest addition to Arco's DupliDisk line of IDE disk mirroring
devices and incorporates Arco's patented  IDE RAID
(Redundant Array of Inexpensive Disks) technology.  It is
designed to fit into two 5.25-inch drive bays and  is
capable of mirroring two IDE, E-IDE or U/DMA drives of any
capacity. Two removable drive caddies provide easy front
access to mirrored drives.

If a hardware failure disables one of the mirrored drives, the
other takes over automatically. External LEDs change color
to indicate a failed drive and an audible alarm alerts the user
of the drive failure but there is no interruption of service.  The
system continues to function normally until the user can find
a convenient time to power down and install a new drive.
Caddies remove easily to facilitate replacement of failed
drives. ARCO's ACP software provides a quick and easy
way to rebuild the new drive. 

HOW DOES IT WORK?
The RAIDcase requires neither an ISA nor a PCI bus slot.  
IDE and power cables provided by Arco connect the
RAIDcase to the computer's onboard IDE controller and
power supply. Once installed, the RAIDcase operates
transparently, providing continuous automatic hard disk
backup and disk fault tolerance. All data sent from 
the PC to the primary drive is automatically duplicated 
(concurrently) to the mirroring drive but the system 
(and end user) sees only the primary drive. 

The RAIDcase uses no jumper settings and requires no
driver, TSR or IRQ. Because it requires no device drivers,
the RAIDcase is essentially operating-system independent. 
It has been tested with systems running Windows 3.x, 95, 98 
and  NT, as well as OS/2, DOS, Unix, Linux, Solaris386,
BSDI and Novell NetWare.  Manufacturer's suggested retail
$435
