The Data Express DE100 is a steel constructed drive carrier and receiving frame for mounting a 3.5"" SCSI or AT/IDE drive into any standard half-height 5.25"" form factor, peripheral slot (minimum 1.7"" high). For SCSI connections, the DE100 is available with single-ended 8-bit or 16-bit (single-ended or differential) connections, including Wide Ultra2 Low Voltage Differential (LVD) interfaces. Some DE100 models support 80-pin single-connect (SCA) 16-bit drive types.
