The real issue isn't usually the data, unless you work with video, large graphics files, big music libraries, or things like that. Typical business data in databases is tiny by the standards of any modern storage device, including those discussed in this thread. Formatted data in word processor files, spreadsheets, presentations and e-mail is bigger, but shouldn't be a problem either unless you have a heck of a lot of it. The storage concern with small drives tends to be the OS and application software, as the previous post suggests.
