The existence of the 750GB from Seagate, although not yet official, proves that the quest for ever larger storage spaces is never-ending.

Likely to target the desktop drive market, I would think that the problem with such a large single drive is the possibility for failure. 750GB is a lot to lose from a single hardware fault.

As users - home, work and otherwise - we are now storing much more data than ever before. Our music collection, digital photos, even home videos are a prime source of data space in the home, and sometimes at work. For the business desktop it is applications, raw data (photos, spreadsheets and analysis output from databases) and for some more complex types, like virtual machine hard drives and others.
