Key Features and Benefits
- The world's first 15K 2.5-inch drive
- Fastest and most reliable drive in the world
- Consumes 30 percent less power than any other 15K drive
- 70 percent smaller than 3.5" drives; enables more drives per system and more airflow to cool processors.
- More performance per U, per GB, and per watt than any other drive
- The world’s first 15K 2.5-inch drive—Seagate® Savvio® 15K
drives are 70 percent smaller than 3.5-inch 15K drives and enable
cooler, faster and much more reliable systems.
- The fastest drive in the world—In addition, the Savvio 15K
drive’s smaller size enables more drives per system, increasing
system performance density and allowing more memory in the
system to match faster processors.
- The highest reliability in the world—A higher reliability rating
than any 3.5-inch drive and the best nonrecoverable error rate,
improved by a factor of 10, rigorously safeguards data.
- More drives per system than 3.5-inch drives allows RAID 5, or
mirroring with hot spares, in 1U servers. Savvio 15K drives bring
enterprise-class reliability to blade servers.
- The Savvio 15K drive consumes less power, runs cooler and
enables more airflow to cool processors.
- Savvio 15K drive performance enables IT to meet its performance
needs in less space and with fewer drives, lowering TCO.
Best-Fit Applications
The Savvio 15K drive is designed for mainstream
enterprise applications:
- Email/collaboration
- File and print
- Database
- Transaction processing
- Rack and tower servers
- Blade servers
- Storage arrays
- Space-constrained specialty applications
