CONNECTIVITY

The HardTape system has a wide range of options providing unparalleled access to your data. Standard cables and bays cover the most common interfaces, custom solutions are available for almost any current interface, and we are working diligently to provide connectivity through all of the interfaces under development.

CAPACITY

HardTape cartridge capacity is expressed in decimal Gigabytes. Operating systems typically report capacity in binary Gigabytes. In video recording applications a more useful measure of capacity is recording time, which is dependent upon the recording format. The table below provides both decimal and binary capacities as well as the recording time for some common formats. A more detailed explanation of cartridge capacity can by found in FAQ Capacity (click here).
Capacity (GB)   Recording Time (Hrs)
Decimal Binary   DV25 DV100
40 37.2   3.0 0.8
60 55.8   4.5 1.1
80 74.5   6.0 1.5
100 93.1   7.5 1.9
120 111.7   9.0 2.2
160 148.9   10.5 2.6

SPEED

There are endless ways to describe the speed (data transfer rate) of a storage device. Most people using HardTape are transferring very large media files to and from the cartridge and therefore the most relevant measurement of speed is the sustained read/write transfer rate. The table below summarizes the maximum sustained R/W data transfer rate for each of the cartridge models. A more detailed discussion of bits vs. bytes; read vs. write; sustained vs. burst; max and min vs. average can be found in FAQ Speed (click here).

HTS-6505-XX (XX=20GB to 120GB) 30 240
HTS-6555-160 53 430
HTS-6575-60 /HTS-6575-80 40 320
HTS-6575-100 53 430
HTS-4805-XX (XX=20GB to 60GB) 25 200

The method of connecting the cartridge to your system will also have an influence on the data transfer rate performance. The table below summarizes the maximum measured data transfer rates for each of the HardTape interface cables and bays. For more information about these rates vs. the often quoted "spec" transfer rates please refer to FAQ Speed (click here).
Interface Cable/Bay Actual Data Transfer

USB Cable /Internal & External Bay 35 280
Firewire Cable / External Bay 40 320
Parallel ATA / IDE Bay 100 800
SATA Cable / Internal & External Bay 150 1200
SCSI 50-pin Narrow Bay 20 160
SCSI 68-pin Wide Bay 40 320
