and why not? and if you want FASTER hdds, then buy the largest you can get, because it has higher data density and its gotta be faster.
I could think of several reasons why people want more and more HDDs and bandwidth like: dms(or adf), iso, ipf, avi, mp3.
BTW, Amiga fans are the only ones that really know how to appreciate HDD space because of 'FDD only' A500..
