Over the years, I have collected a lot of datasets that I have attempted to archive on the university file server. While computer space is not very expensive these days, it is not free. These files have, collectively, far exceeded the standard faculty allotment.
Fortunately, we finally found a simple solution: The HP Personal Media Drive, which is an external hard-drive with 500GB of memory. Years worth of files only take up a small fraction of the space. And just by connecting an USB port, I can quickly backup my entire laptop hard-drive. It is also very portable. That is a lot of peace of mind for under $200.
