But I'm refering to a small drive for just the OS and some apps.......Thats all.......Through experience I've found that "some apps" tends to grow over time and can soon fill up a smaller drive. My 37Gb Raptor filled up quicker than I expected. For example 110Mb just for a read-only Adobe Acrobat. And if you have a digital camera those images have to be stored somewhere.Bear in mind a substantial part of any HD is reserved for use by the system. Once you get to about 75% used a drive does become quite inefficient.
