Ultrastar 15K73 hard disk drives

High-performance. Capacity. Technology.

Family/Series: Ultrastar 15K73 (DK32EK)
Model #: HUS157373EL3800 (DK32EK-72NC)
Part #: 08K2403
Capacity: 73.9 GB
Interface: Ultra320 SCSI, 80-pin (SCA-2 LVD)
Data Buffer (Cache): 8 MB
Rotational Speed: 15,037 RPM
Seek Time: 3.9 ms (avg)
Latency: 1.99 ms (avg)
 

Highlights:

  • Rotational speeds of 15,000 RPMs and an average seek time as low as 3.9ms to help boost performance
  • Capacities of 73 GB or 36 GB provide configuration flexibility
  • Incorporates technologies such as Fluid Dynamic Bearing motors, (FDB), to help increase the reliability and robustness of the drive
  • First server-class 15,000 RPM drive to incorporate antiferromagnetically coupled technology, (AFC), also known as “pixie-dust”. AFC enables higher areal densities by improving thermal-stability, which maintains data-integrity

     

    Advanced drive technology
    The Hitachi Ultrastar 15K73 is the 3rd generation of 15,000 RPM enterpriseclass hard drives from Hitachi. Leveraging award-winning technologies that have generated proven quality and high-performance, the Ultrastar 15K73 incorporates Fluid Dynamic Bearing motors (FDB) to contribute to increased capacity by enabling high-track density through a more precise position of the head. AFC Media, also known as "pixie dust", is an industry-first in 15,000 RPM enterpriseclass hard drives, enabling higher areal densities by improving thermal stability, which in turn, maintains data integrity.

    Designed for both high-performance and high-reliablity, the Ultrastar 15K73 was developed with powerful processors and read-write channels, advanced servo coupled technology, (AFC), also known controls to improve seek and settle times, and overall improved mechanical stability to excel in today's demanding data-processing environments.

    Reliability features
    Research and development teams throughout Hitachi Global Storage Technologies have a combined 80 years of award-winning hard drive development experience and technology that satisfy increasingly complex computing requirements. The Ultrastar 15K73 builds on this tradition.

    In order to ensure data-protection, the Ultrastar 15K73 incorporates advanced reporting tools such as Self-Monitoring Analysis and Reporting Technology (S.M.A.R.T.) to signal potential drive problems. write channels, advanced servo Reliability is enhanced with load/unload technology and glass-substrate disks which provide a robust solution and high rotations speeds.

    Support for advanced applications and interfaces
    The Ultrastar 15K73 provides high-datathroughput for data-intensive applications with the Ultra 320 SCSI (backward compatible) interface. Also available in a 2Gbits/s Fibre Channel interface to allow for flexible, high-bandwidth data transfers.
