Store more…faster!
Hitachi delivers its highest-performing hard drive ever with the introduction of the Ultrastar 
15K147. With average seek times as fast as 3.3ms, average latency of 2ms, and as much 
as 33 percent more in I/Os per second than its 10,000 RPM rivals, enterprise customers 
can access their data more quickly and effi ciently. These performance characteristics of the 
Ultrastar 15K147 make it the ideal solution for mission-critical enterprise computing environ-
ments like online transaction processing, data analysis, and other multi-user applications.
Proven design for extreme performance and reliability
Performance and reliability are key requirements for enterprise-class hard drives. The 
mature design of the Ultrastar 15K147 ensures greater reliability which helps enable shorter 
qualifi cation times. Several key technologies are designed into Ultrastar drives to ensure high 
reliability, enhance performance and protect customer data. The Ultrastar 15K147 incorporates 
Rotational Vibration Safeguard (RVS) technology to maintain drive performance in multi-drive 
systems where rotational vibration is likely to occur. Fluid dynamic bearing (FDB) motors 
deliver quieter drives with improved data integrity. Hitachi offers the only enterprise-class hard 
drive utilizing a head load/unload ramp which helps minimize drive failures caused by handling 
damage during integration.
