Cheetah 15K.3 Product Overview
The Lowest Cost-per-I/O Disc Drive
The new Cheetah 15K.3 enterprise disc drive runs faster, cooler and quieter than ever, and is the only 15K drive backed by two previous generations of 15K experience. The Cheetah 15K.3 is offered in 73-, 36- and 18-Gbyte capacities including Ultra320 SCSI and 2-Gbit/sec Fibre Channel. The Cheetah 15K.3 is the lowest cost-per-I/O disc drive because it delivers 35 percent more I/Os per second (IOPS) than the 10K. Fewer 15K drives are needed to deliver the same IOPS as 10K, leading to greater overall system reliability and savings in hardware, space, power, cooling and IT administration costs, resulting in lower total cost of ownership.

Features and Benefits
| Features | Benefits |
| Lowest cost-per-I/O drive | The Cheetah 15K.3 delivers 35 percent more IOPS than 10K, allowing fewer drives to be used to meet the system’s I/O requirements. |
| Third-generation 15K | The only 15K based on two previous generations of 15K experience |
| Whisper-quiet acoustics | Quiet drive for workstations and office-area servers |
| The highest reliability rating | Worry-free 24x7 operation |
| Incredibly low power consumption | Multi-drive systems draw less wattage of power and require fewer fans for cooling. |
| 15K-RPM speed | 35 percent more IOPS and 29 percent faster minimum sustained transfer rate than 10K |
| Most widely used 15K-RPM disc drive | Zero-risk decision for deploying new storage or for upgrading existing systems |
| Design Service Center | Lowers the cost of deploying storage solutions by testing system-level reliability early |
| Fastest interfaces | Data integrity assured via the Seagate Ultra320 SCSI implementation beginning and ending with the strongest and cleanest signal |
| 2 interfaces for each capacity | Ultra320 SCSI and 2-Gbit/sec Fibre Channel for each capacity make the Cheetah 10K.6 the most versatile 10K drive on the market. |
| Millennia of combined engineering and manufacturing experience | Seagate is the dependable partner offering the most reliable products, the best technology and the best services. |
Best-Fit Applications
The Cheetah 15K.3 is ideal for I/O-intensive applications or those with a high access density. Examples include the following applications for workstations, high- to mid-range servers, NAS and SANs:
- RAID
- File and print—higher client volume environments
- E-mail/groupware—higher client volume environments
- Decision support—databases, data-mining and warehousing
- Business processing—CRM, ERP, OLTP
- CAD/CAM
- Engineering/computing
- Data streaming—imaging, A/V
