  Savvio 15K
Boost performance density while cooling systems down


73 GB and 36 GB • 15K RPM • 3 Gb/s Serial Attached SCSI (SAS)


Savvio 15K is the world’s first 15K 2.5-inch drive, and provides the highest available performance and reliability while ensuring ultra-low power consumption.

The Seagate® Savvio® 2.5-inch enterprise hard drive is 70 percent smaller than 3.5-inch drives, enabling more drives per system and providing higher performance and reliability while ensuring ultra-low power consumption, reducing thermal loads in data centers. The Savvio 15K drive is well suited for a broad range of mainstream enterprise applications in both large enterprise data centers and small- to medium-size businesses.


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


Product Description
The Savvio 15K drive is the first 15K 2.5-inch drive in the world and provides the highest performance and reliability possible while ensuring ultra-low power consumption. The Savvio 15K drive delivers more performance per U, per GB and per watt than any other drive in the world. The Savvio 15K drive offers the advanced SAS interface and capacities of 36 GB and 73 GB.

The Seagate Advantage

  • Seagate pioneered the 2.5-inch enterprise platform with great success. This secondgeneration drive builds on that success with a new, record-breaking reliability rating and the addition of the 15K-RPM line of Savvio drives.
  • The fastest drive in the world. Chosen by HP for their record-breaking TPC performance benchmarks.
  • The Savvio 15K drive completes the Seagate 2.5-inch drive portfolio by offering a range of choice of high-capacity 2.5-inch, 146-GB, 10KRPM drives and the highest-performance 15K spindle speed and seek times.


Enabling New Opportunities

  • Solution designers value the design flexibility to provide more competitive solutions afforded by the smaller size, lower power consumption, greater performance and greater reliability of Savvio 15K drives.
  • The Savvio 15K drive’s 70 percent smaller size enables more airflow to cool processors and enables more room for more memory to further increase system performance.
  • The Savvio 15K drive provides the performance needed for virtualization and high-accessdensity applications.
  • The Savvio 15K drive provides the highest reliability, ensuring higher uptime in rigorous enterprise environments.
  • The Savvio 15K drive provides faster performance than 3.5-inch 15K drives while consuming over 30 percent less power.
