Cheetah 15K.4

Mainstream enterprise disc drive

PRODUCT DESCRIPTION

The new Cheetah 15K.4 enterprise disc drive offers an unprecedented blend of high performance and cost effectiveness. Seagate has dramatically improved Cheetah speed by delivering seek times as fast as 3.3 msec, latencies as low as 2 msec and an increase in data rates of up to 30 percent over the previous generation. This enables the Cheetah 15K.4 to meet throughput requirements under highly demanding conditions with fewer drives, significantly

wering TCO. And the Cheetah 15K.4 achieves these

lo performance gains while maintaining the same power, shock and acoustic characteristics of its 15K.3 predecessor.

THE SEAGATE ADVANTAGE

• The Cheetah 15K.4 is the lowest cost-per-performance disc drive from Seagate, benefiting from the team experience acquired over four generations of Cheetah 15K-RPM products.

• The Cheetah 15K.4 delivers 30 percent more IOPS and 20 percent faster response times than 3.5-inch 10K drives.

• Cheetah 15K.4 enables higher performance with fewer drives, and fewer drives mean lower total cost of ownership.

APPLICATIONS

Environments where reliability and I/O performance are paramount, including:

• E-mail

• Online transaction processing (OLTP)

• Enterprise, Internet and e-commerce servers

• Database server applications, data warehousing and mining

• Storage area networks (SAN) and supercomputers

• Multi-user multimedia, digital A/V and image processing

• Graphics and medical imaging, scientific workstations

ENABLING NEW OPPORTUNITIES

• Cheetah 15K.4 drives are leading storage solutions towards greater performance/value parity with today’s dynamic, on-demand enterprise systems.

• Cheetah 15K.4 drives offer lasting value, enabling systems to keep up with growing performance needs over a longer period of time.

• Storage Performance Council (SPC) testing, which includes e-mails in its workloads, verifies the cost efficiency of Cheetah 15K drives. SPC test results rank servers equipped with Cheetah 15K drives above the majority of all servers tested. (All top SPC price/ performance ser
