Cheetah® 15K.5 Mainstream enterprise hard drive storage 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 timeto-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.
