The Macsense QuDi Portable Drive is one of the lightest external storage drives available, and the most flexible as well. You must have at least one Base and one Caddy for QuDi to work.

Choose either a USB or FireWire base. Both models are cross- platform compatible between Macs and PCs and Plug and Play. They are also interchangeable so for example, if you use USB in your office and FireWire at home, the same Caddy will work in either base.

Next choose a Caddy in whatever capacity fits your need, 10GB, 20GB, 32GB or 48GB. Snap in the caddy and you have removable storage of up to 48GB. Leave one FireWire Base at the office, and bring a USB Base for the road, share a 10GB caddy between work and home, or move up to higher capacities. You can always add more Caddies as your need for portable or removable storage grows. The detachable Base-and-Caddy design allows you to mix and match between different connection interfaces and the caddy has several capacity choices to meet your needs without any redundant investment.

Mac users can protect and configure Caddies for better security. The unique design of the Macsense QuDi Portable Drive combined with these valuable software tools make QuDi the best and most versatile solution in portable data storage.
