Description:

Barracuda 180 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.

  • 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)
