Seagate Cheetah 15K.7 Hard Drives

Seagate Cheetah 15K.7 drives reduce costs for 3.5-inch Tier 1 solutions, helping to sustain business. They have the highest performance, capacity and reliability of any 3.5-inch mission critical drive. The drive has up to 600 GB of capacity, which reduces storage costs per GB and increases capacity per watt. The Cheetah 15K.7 drive includes Seagate PowerTrim technology, which dynamically optimizes drive power consumption at all levels of activity.

The drive is leveraged from the highly successful Cheetah 15K.6 platform and has the industry’s highest reliability rating, reducing drive replacement costs. The drive is available with a SAS or FC interface and is the highest-performing 3.5-inch drive in the world. The drive reduces RAID rebuild times while minimizing reliability risks. The SAS drives will support 6-Gb/s transfer rates as part of the new SAS 2.0 feature set. SAS 2.0 was developed to provide additional signal and data integrity features to enable SAS to be ideally suited for use in high-end network storage applications.

The Cheetah 15K.7 drive is the second generation of Cheetah drives available with a Self-Encrypting Drive (SED) option, providing government grade data security and instant secure erase for drives reused, recycled or returned for expired lease, repair or warranty.  *Requires TCG-compliant host or controller support.

    Lowest Cost of Ownership

  • Seventh-generation Seagate Cheetah 15K.7 drive is the fastest, highest capacity and most reliable ever.
  • Lower watts/GB ratio helps achieve reduced power and cooling costs while optimizing capacity requirements.
  • Higher performance with fewer drives—reducing support infrastructure, physical space requirements and storage management costs.
  • The highest reliability of any 3.5-inch drive, with increased system reliability due to the need for fewer drives.

    Highest Reliability

  • Seagate continues to focus on reliability and data protection. MTBF is an industry-leading 1.6 million hours.
  • Seagate-exclusive enhanced Error Correction Code better maintains performance throughout the life of the drive and reduces the probability of lost data.
  • The third generation of Seagate-exclusive Background Media Scan proactively scans the media for potential defects during drive idle time. It enables incipient errors to be corrected before data is lost.
  • Quick and Robust Download feature loads new firmware in seconds, with built-in protection to ensure no corruption in the event of a power failure during firmware switch.

    Strong Enough for National Security

  • The Cheetah 15K.7 drive is available in SED or FIPS SED models; both eliminate the need to overwrite or physically destroy drives, enable secure return of drives for warranty or expired lease purposes, and allow organizations to securely repurpose or sell hard drives. For added physical security and more stringent regulatory compliance needs, the FIPS SED model is FIPS 140-2 Validated for use with sensitive but unclassified or protected (A or B) class data.
  • These Seagate Secure models help OEMs and system builders gain competitive advantage, differentiate solutions (with strong data security), sell to new customers (that require strong data security), and protect brand equity (and customer confidence).

   Key Advantages

  • Third-generation perpendicular recording delivers up to 600GB.
  • Unprecedented performance with sustained data rate of up to 204MB/s—a 16 percent increase over last generation.
  • Industry’s highest 3.5-inch drive reliability at 1.6-million-hours MTBF.
  • Seagate PowerTrim technology provides a 62 percent improvement in GBs/W at idle over typical 3.5-inch hard drives.
  • Read/write advances deliver non recoverable error rate of 1x10E16.
  • Available in 4Gb/s FC or 6Gb/s SAS interfaces (supports SAS 2.0 feature set).
  • TCG-compliant Self-Encrypting Drive (SED) option cuts IT drive retirement expenses while securely protecting data and is one of the easiest, most cost-effective security measures you can implement.
  • FIPS Self-Encrypting Drive option provides all the benefits of SED and is NIST certified to meet U.S., Canada and U.K. federal data encryption compliance requirements.

   Best-Fit Applications

  • Business and Transaction Processing
  • Storage Area Networks and Networked Attached Storage
  • E-mail, Decision Support, Internet and e-commerce
  • Government Grade, Data-at-Rest Security when drives leave your control
  • Drive Retirement Cost Reduction and Drive Life Extension Strategies
