With the announcement of Archos PMA 400 they also announced the ARCDrive; a 4GB USB keychain drive. The ARCDrive uses a 4GB Hitachi microdrive to deliver high capacity storage in such a small form factor. The ARCDrive weighs in at 1.4 ounces and is no bigger than most MP3 devices at 1.8 x 1.7 x 0.5 inches. The drive will be a perfect companion to the PMA400 as you can plug it into the device and use it as an extra 4GB of storage if 40GB isn’t good enough for you!

The drive should be available near the end of the month for around $149.95 US.
