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 perform- ance 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 appli- cations 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 perform- ance beyond that offered by single hard drives.15K drives are ideal for RAID systems as they combine optimum performance with superb reliability.
