BOULDER, Colorado, August 20 /PRNewswire/ --

ProStor Systems, the leading developer of removable disk 
(http://www.rdxstorage.com/) storage systems, continues to expand market
penetration of its removable disk storage solutions by announcing the
availability of RDX(R) technology with entry-level HP ProLiant servers and HP
xw series workstations. These removable disk backup solutions are easy to use
and affordable, and allow small businesses to store data off-site as part of
their disaster recovery plans. HP StorageWorks RDX removable disk cartridges

eId=450&FamilyId=2831&LowBaseId=21630&LowPrice=$2,499.00), in 160 GB and 320
GB capacities, are available immediately.

"The adoption of RDX technology proves that users value the speed and
reliability of disk, but need high-capacity removable media for data
protection and disaster recovery applications," said Steve Georgis, CEO and
president of ProStor Systems. "Today's announcement of the availability of
RDX technology with entry-level HP servers and HP workstations provides
customers with an integrated data protection solution that offers all the
performance attributes of disk and the offsite storage capabilities of
removable media."

With a current installed base of more than 85,000 end users worldwide,
RDX backup and data retention solutions have captured 90 percent of the
removable disk market for business server and workstation backup. A recent
IDC report estimates that revenue from removable disk solutions will exceed
US$500 million by 2012.*

"Increasingly, SMBs are looking at low-cost, high-capacity removable
storage to meet their ever growing data storage needs," said Robert Amatruda,
research director tape and removable storage at IDC. "By adding ProStor's RDX
technology to its removable portfolio, HP is demonstrating its commitment to
address customer needs beyond its current set of complementary storage
solutions."

RDX technology reduces the typical data backup window from hours to
minutes and allows users to back up 100 GB of data in less than an hour.
Additionally, RDX disk systems include a dock and cartridge that contains a
mobile 2.5-inch hard disk drive in a shock-proof design. Its robust design
ensures customers have a secure, durable backup system that can withstand
environmental contaminants and sustain a fall of up to one meter. View

system.

RDX solutions are compatible with most popular backup software. The
removable disk systems are forward and backward compatible, meaning today's
docks will work with tomorrow's cartridges and vice versa. For example, the
highest capacity RDX cartridge currently available is fully read/write
compatible with the very first RDX systems shipped two years ago.
