•  Fifth-generation Cheetah 15K drive is the fastest, highest

capacity and most reliable ever.

•  Cheetah 15K.5 drive performance and reliability enable

lower TCO for enterprise applications.

•  15K RPM and fast seek times deliver the fastest time-

to-data, resulting in 30 percent more IOPS and over 20
percent faster response times than 3.5-inch 10K drives.

•  Higher performance with fewer drives—reducing support

infrastructure, physical space requirements and storage
management costs

•  The highest reliability of any 3.5-inch drive, and increased

system reliability due to the need for fewer drives

•  Seagate continues to focus on reliability and data

protection. New features in this generation have improved
the nonrecoverable error rate by a factor of 10.

•  Seagate-exclusive IRAW (Idle Read After Write) enhances

data protection by verifying—during drive idle time—that
data in the drive buffer was properly written.

•  Seagate-exclusive enhanced Error Correction Code

better maintains performance throughout the life of the
drive and reduces the probability of lost data.

•  The second generation of Seagate-exclusive Background

Media Scan (BMS) proactively scans the media for
potential defects during drive idle time. It enables
incipient errors to be corrected before data is lost.

•  The Cheetah 15K.5 drive is designed and manufactured

by the same teams that successfully delivered the past
four award-winning generations.

•  Presales and technical support at 1-800-SEAGATE
•  Expert email support and complete historical web

content available online

•  Experienced support staff
•  Seagate Design Service Centers (DSC) help companies

transform innovative ideas into viable products.
