Seagate ST39204LC Cheetah 18XL 9.19GB 
Ultra SCSI Wide 10,000RPM Hard Drive


Description:

Cheetah 18XL 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.

Ultra160 SCSI uses negotiated transfer rates. These transfer rates will occur only if your host adapter supports these data transfer rates and is compatible with the required hardware requirements of the I/O circuit type. This drive also operates at Ultra160 data transfer rates.



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
  • Firmware downloadable via SCSI interface
  • Selectable even byte sector sizes from 512 to 4,096 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 correction length of 240 bits with a guaranteed burst correction length 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
  • 1:1 Interleave
  • Zoned bit recording (ZBR)
  • Vertical, horizontal, or top down mounting
  • Dynamic spindle brake
  • 4,096 kbyte data buffer
  • Hot plug compatibility (Section 9.6.4.2 lists proper host connector needed) for “LC” model drives
  • Drive Self Test (DST)
