Most people won't have any use for this thing, but if you need to analyze evidence from a hard drive without changing its content, you'll probably be interested in the Forensic RTX.
Basically, it's an external hard-drive enclosure that can house four 3.5-inch hard drives at a time. However, it differs from any regular external enclosure in many ways.
First, the device supports both the currently popular SATA and the older IDE interface standards. This means it can handle the hard drives of current desktops as well as those that were made more than 10 years go. Secondly, two of the hard drive bays feature WiebeTech's proprietary write-blocked technology that guarantees with an absolute certainty that you, and only you, can read from the hard drive.
The hard drive bays even have locks, to make sure they can't be physically tampered with. Another bonus is when you need to replace the hard drive, you don't have to unscrew anything. You just need to insert the hard drive the way you wold insert a CD in the CD Drive and then close the bay's door.
The Forensic RTX feature a plethora of connection options, including USB 2.0, FireWire 800, FireWire 400, and eSATA.
The Forensic RTX's chassis is made of sturdy aluminum that provides a rugged durability and a cooling solution.
Like I said earlier, most of us won't need one of these, but if you happen to have a use for it, make sure you start saving. The Forensic RTX can easily dig a hole in your wallet with its hefty price tag of $1,500.
