Savvio® 15K.2 Highest-performing, greenest drive for enterprise storage systems The Innovative Market Enabler The Savvio 15K.2 drive enables OEMs and system designers to increase revenue by building more compelling solutions. It provides the highest performance for Tier-1 mission-critical storage solutions: • 115 percent improvement in system-level performance over 3.5-inch 15K drives • 10 percent faster than 3.5-inch 15K drives • 30 percent faster than 2.5-inch 10K drives The Savvio 15K.2 drive is the innovative market enabler for highperformance, low-power (green) solutions. Its 2.5-inch form factor enables OEMs and system designers to sell more systems-especially into space-constrained IT environments. Enabling More Powerful Solutions The drive's implementation of 6-Gb/s SAS improves scalability, which makes it ideally suited for use in high-end network storage solutions. The SAS 2.0 feature set supports more robust topologies that can communicate over broader distances with high signal integrity to enable more powerful storage solutions. The Savvio 15K.2 drive is the industry's only 2.5-inch 15K SelfEncrypting Drive (SED) to provide government-grade data security.* The Savvio line has the industry's highest field-proven reliability. Unified Storage Architecture By using SFF drives, a common SAS interface and SED security* capabilities, Seagate Unified Storage architecture delivers a best-ofbreed foundation for powerful yet simple storage solutions for the data center. What's more, the Unified Storage architecture: • Enables superior multi-drive servers and storage solutions that reduce costs and design complexity for OEMs and other system builders • Lowers TCO while improving ROI by providing large enterprises and SMBs lower-cost multi-drive servers and storage • Reduces storage complexity and enables peace of mind for the IT manager Specifications 146 GB1 73 GB1 Model Number Capacity ST9146852SS ST9146752SS2 ST973452SS ST973352SS2 Formatted 512 Kbytes/Sector (GB) External Transfer Rate (MB/s) 3-Gb/s Serial Attached SCSI 6-Gb/s Serial Attached SCSI Performance 146.8 73.4 300 300 600 600 Spindle Speed (RPM) Average Latency (ms) Seek Time Average Read/Write (ms) Track-to-Track Read/Write (ms) Sustained Transfer Rate, Outer to Inner Diameter (MB/s) Cache, Multisegmented (MB) Configuration/Reliability 15K 2.0 2.9/3.3 0.2/0.4 160 to 122 16 15K 2.0 2.9/3.3 0.2/0.4 160 to 122 16 Disks Heads Nonrecoverable Read Errors per Bits Read Annualized Failure Rate (AFR) Power Management 2 4 1 sector per 10E16 0.55% 1 2 1 sector per 10E16 0.55% Typical Op (amps) +12V/+5V Power Idle (W) Environmental 0.40/0.43 4.1 0.34/0.42 3.7 Temperature, Operating (°C) Temperature, Nonoperating (°C) Shock, Operating: 2 ms (Gs) Shock, Nonoperating: 2 ms (Gs) Acoustics Idle (bels-sound power) Vibration, Operating:
