High performance and proven reliability

Cheetah® 15K.7 hard drives have field-proven reliability with the performance and capacities of legacy 3.5 inch mission-critical enterprise storage.

Join the latest ranks of IT shops worldwide by exploring the cost-effective 2.5 inch form factor alternatives, Savvio 15K and 10K, or if you are locked into 3.5 inch, take a look at Constellation ES:

  • Switch to Savvio 15K for maximum performance
  • Switch to Savvio 10K for the perfect balance of high performance and high capacity
  • Switch to Constellation ES for five times more storage capacity

By making the switch, you will also benefit from migrating from 4Gb Fibre Channel to 6Gb SAS for improved performance and improved data integrity with a future.
