I am still on a previous version of Sibelius, but I don't need an extra hard drive to run it at all, matter of fact, it lives and works well frm the internal C: drive on my rather long in the tooth XP driven laptop. That includes their "lite" version of the software synthesizer.

From the Sibelius website:

Quote:


Minimum requirements for Sibelius 7 software only

Windows: Windows Vista SP2 with the Platform Update Pack or later, Windows 7 SP1 or later, 1 GB+ RAM, 750 MB hard disk space, DVD-ROM drive

Mac: Mac OS X 10.6.7 or later, Mac OS X 10.7, 1 GB+ RAM, 750 MB hard disk space, DVD-ROM drive






I don't think you would have to be concerned about running Sibelius 7 from the internal drive at all. It is not multitracking audio.
