Hitachi Ultrastar 15K300
enterprise hard drives
15,000RPM (15K) hard drives are rapidly becoming the drives of
choice for mission-critical enterprise computing environments such
as Online Transaction Processing (OLTP). The major players in the
server manufacturing industry are leading the way, but this shift
also represents an excellent opportunity for systems builders
aware of the potential gains.
So what are the advantages of 15K drives over their 10,000RPM
(10K) equivalents? How can Hitachi help you embrace this
new technology? And what about compatibility with other
components? This Resource Guide has been designed to
provide you with all the information you need, from both
business and technical perspectives.

Down to business
15K drives – the opportunity
The emergence of 15K hard
drives has created a wealth of
new market opportunities for
systems builders. Until recently,
many systems builders have
continued to use traditional
10K hard drives within their
servers, primarily for financial
reasons. However, as the
performance benefits of 15K
hard drives become increasingly
apparent, more and more
systems builders are recognising
the potential they offer.
Your customers need performance to improve their productivity,
and reliability to protect their user
data and reduce their total cost
of ownership (TCO). Using 15K
drives in your products, you will
be able to increase sales within
your existing customer base by
offering a higher quality product,
which delivers the required
performance and reliability at
a higher profit margin. Moreover,
enhanced server capabilities
will enable you to break into new
markets, allowing you to compete
in fields previously dominated by
the major worldwide players.
15K drives – the market
context
The ultra-fast 15K drives are
designed to meet the needs of
a key element within the storage
hierarchy: enterprise computing
environments, which primarily
deal with high bandwidth applications requiring fast responses.
This may translate to systems
with multiple users, or systems
with many small items of data
stored anywhere within the disk
array, or both. Think about
transaction-based systems,
web servers and SQL database
applications. In these situations,
the 24% speed increase offered
by 15K drives is clearly beneficial.
Many systems builders are now
looking to RAID systems to
provide capacity and performance beyond that offered by
single hard drives.15K drives are
ideal for RAID systems as they
combine optimum performance
with superb reliability.
