Product Overview and Benefit

Cheetah® 15K.5 - Mainstream Enterprise Hard Drive Storage

Best Price/Performance, Lowest Cost of Ownership Disc Drive

The new Cheetah 15K.5 enterprise disc drive employs innovative perpendicular recording technology to set new standards for storage cost effectiveness. While doubling available capacity to 300GB, the Cheetah 15K.5 also delivers 36 percent higher sequential performance. This enables enterprises to meet their throughput and capacity requirements with fewer drives, significantly reducing total cost of ownership (TCO). Seagate® designed the Cheetah 15K.5 for maximum reliability in demanding enterprise applications, including a nonrecoverable error rate that’s been improved by a factor of 10. Cheetah 15K.5 incorporates such Seagate-exclusive features as IRAW (Idle Read After Write), enhanced ECC (Error Correction Code) and BMS (Background Media Scan) to safeguard data integrity in the most rigorous environments.

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.

Frequently Asked Questions

Frequently asked questions for Fibre Channel (FC) Hard Drives, including information on usage, configuration, and compatibility.

1. What is a Fibre Channel hard drive?

A Fibre Channel (FC) hard drive is an enterprise storage device that uses the Fibre Channel protocol to connect to storage area networks (SANs). It’s designed for high-speed, high-availability environments where large amounts of data must be stored and accessed quickly.
2. What systems are Fibre Channel hard drives used in?

FC hard drives are typically found in enterprise SANs, data centers, and high-performance servers. They connect through Fibre Channel controllers and switches to deliver fast, reliable access to storage pools.
3. How do Fibre Channel hard drives differ from SAS or SATA drives?

Fibre Channel drives use the FC protocol for connectivity, providing higher throughput, low latency, and robust multi-path redundancy. Unlike SATA (consumer) or SAS (enterprise direct-attach), FC drives are built for large-scale SAN infrastructures.
4. What capacities are available for Fibre Channel hard drives?

FC hard drives are available in a range of capacities, from a few hundred gigabytes up to several terabytes. However, many have been replaced in modern systems by FC-attached SSDs and SAS drives.
5. Are Fibre Channel hard drives hot-swappable?

Yes. In SAN and enterprise server environments, FC drives are typically hot-swappable when used with compatible enclosures and controllers.
6. Can Fibre Channel hard drives be used in regular desktops?

No. Fibre Channel drives require specialized HBAs (Host Bus Adapters), switches, and infrastructure. They are not compatible with standard desktop or consumer systems.
7. Why are Fibre Channel hard drives still used today?

Fibre Channel hard drives continue to be used in enterprise environments that rely on SANs for centralized storage, high availability, and consistent performance. Many organizations also use them to maintain legacy Fibre Channel infrastructures.
