Lowest Cost of Ownership
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
Highest Reliability
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.
