Trek upgrade kit vs. internal bare drive.
Trek offers a full line of removable upgrade kits. Removable kits are unique to each system. The drive is housed inside a "caddy". Caddies are unique to each system and are incorporated in the design of each system. For example, IBM’s caddies will not work in a Toshiba system and vise versa (see below for pictures of various caddies). The overall design of the caddies allows users to simply flip a switch or open the keyboard to remove the caddy for quick and easy access to the hard drive. The caddies also incorporate a standard connector, again unique to each system. When a caddy is inserted into a system the pins automatically make connection for data and power transfer. This makes upgrading and swapping of hard drives easy without having to deal with ribbon cables and power connectors. It also prevents the user from actually touching the hard drive’s circuit board, which is a common reason for hard drive failures.

Internal hard drives are simply bare drives with no caddy, connector or power cable. Installation requires opening the portable as recommend by the manufacturer and may require a qualified service technician. This method can lead to drive failures and if the person servicing the specific portable computer has no knowledge or experience can damage the system. Also today’s newer drives will not fit in yesterday’s older caddies, with drives becoming thinner and locations of screw holes changing its hard to figure what will work and what will not work. Our Trek caddies offer universal mounts, meaning, Trek caddies will accommodate older drive mounts and new drives mounts along with various thickness’. Although bare drives are offered by our authorized dealers and distributors it is recommended that users either install a upgrade kit by Trek or have an authorized service center install a bare drive.
