Seagate Cheetah 73 - ST173404LC 73.4GB Ultra-SCSI 
Wide 10000RPM 80-Pin Hard Drive (ST-173404LC)




Description:

Cheetah 73 drives combine giant magnetoresistive (GMR) heads, partial response/maximum likelihood (PRML) read channel electronics, embedded servo technology, and a wide Ultra160 SCSI interface to provide high performance, high capacity data storage for a variety of systems including engineering workstations, network servers, mainframes, and supercomputers.



Features:

  • Integrated Ultra160 SCSI controller
  • Multimode SCSI drivers and receivers—single-ended (SE) and low voltage differential (LVD)
  • 16 bit I/O data bus
  • Asynchronous and synchronous data transfer protocol (supports Ultra160 transfer rate)
  • Firmware downloadable via SCSI interface
  • Selectable even byte sector sizes from 512 to 2,064 bytes/sector
  • Programmable sector reallocation scheme
  • Flawed sector reallocation at format time
  • Programmable auto write and read reallocation
  • Reallocation of defects on command (post format)
  • Enhanced ECC (maximum burst corrections length of 240 bits with a guaranteed burst correction of 233 bits)
  • Sealed head and disc assembly
  • No preventative maintenance or adjustment required
  • Dedicated head landing zone
  • Embedded servo design
  • Self diagnostics performed when power is applied to the drive
  • Zoned bit recording (ZBR)
  • Vertical, horizontal, or top down mounting
  • Dynamic spindle brake
  • 4,096 kbyte data buffer (16,384 kbyte option on LWV and LCV models)
  • Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for LC and LCV model drives
  • Supports SCSI bus fairness
