Seagate Cheetah 15K.4 146GB ST3146854FC 15K 2Gbps Fiber Channel Hard Drive – Brand New
Lowest Cost of Ownership
• Cheetah 15K performance and reliability enable lower
TCO for a wide variety of enterprise applications.
• Cheetah 15K RPM and fast seek times deliver the
fastest time-to-data, resulting in 30 percent more IOPS
and more than 20 percent faster response times than
3.5-inch 10K drives.
• Cheetah 15K enables higher performance with fewer
drives. Fewer drives reduce support infrastructure,
physical space requirements and storage management
costs.
• Cheetah 15K drives have the highest field-proven
reliability in the industry and further increase system
reliability due to the need for fewer drives.
• This fourth-generation Cheetah 15K is the fastest,
coolest, quietest and most reliable ever.
