3.5” 68-Pin SCSI Wide Differential Hard Disk Drive

The 3.5" 68-pin SCSI Wide Differential Hard Disk Drive (HDD) is a proprietary FPGA based design that provides a long term solution for replacement of obsolete SCSI drives.  Wide Differential is also called High Voltage Differential (HVD).  The design provides a transparent interface from the SCSI bus to a COTS 2.5" HDD.  The drive can be configured to provide specific capacities for applications that only work with low capacity drives.



  • Drop in replacement for 68‐pin SCSI Wide Differential drives
  • Capacities currently up to 320 GB.  Larger capacities available as 2.5" COTS SSD capacities increase
  • SCSI Wide Differential Interface (High Voltage Differential) provides transfer rates up to 40 MB/S
  • Fast, efficient field replacement
  • High density mass storage in 3.5" form factor
  • 35% lighter than standard 3.5" SCSI drive
  • Compatible with CPUs with SCSI Wide Differential (High Voltage Differential) controller
  • No additional software required
  • SCSI ID Selection 0-15
