The acquisition builds on HGST's strategy to enhance the overall value of
datacenter storage by integrating HGST SSDs with software. VeloBit's SSD
caching software dramatically accelerates applications and increases server
density by enabling higher I/O performance, lower latency, and more efficient
usage of processor and storage resources.

Both the VeloBit acquisition and the proposed sTec acquisition by Western
Digital reflect acceleration by its HGST subsidiary in the fast growing and
strategic enterprise SSD space, augmenting its technology position and IP
portfolio with additional engineering and design resources.

"In VeloBit we saw a great team that has developed and commercialized
breakthrough I/O optimization software," said Mike Cordano, president, HGST.
"The acquisition of VeloBit is an important step in our strategy to develop
robust software capabilities to augment our successful SSD product portfolio."

"We are convinced that the best way to meet our customers' needs is to tightly
integrate storage optimization software with the hardware," said Duncan
McCallum, co-founder and CEO of VeloBit. "In HGST we have found the ideal
partner to continue to develop our ground-breaking caching, compression, and
cache coherence technology. This acquisition will enable us to continue to
expand the range of products and services we offer to our customers."

VeloBit has won multiple competitive product benchmarks in the areas of I/O
acceleration and server density optimization. VeloBit HyperCache was chosen by
Storage Magazine as a 2012 Storage Product of the Year.

VeloBit was founded in September 2010 by an experienced team of storage
industry experts and entrepreneurs to commercialize inventions in caching and
data compression. The company was funded by Fairhaven Capital and Longworth
Venture Partners.

Wells Fargo Securities, LLC has acted as the financial advisor to VeloBit in
connection with this transaction.
