Cheetah® 15K.6

Highest capacity and reliability in mission-critical storage

Lowest Cost of Ownership

•

Sixth-generation Seagate® 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.

•

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

MTBF Improvement
