I'm getting ready to put my HDD in for stripping. While the computer is in the shop, I'm considering adding another HDD. Presently I have 120GB HDD with 512M memory, 2700 DDR Memory. Runs at 166 mhz and uses an AMD Athlon processor. 1.20GHZ (Frankly, I don't know what the majority of that means. I've just got it written down so when you computer techies ask I can tell!) I've been working with digital images since only May of this year, and am now down to 35% free space. Any suggestions as to how much I need to add to my HDD so I can work quickly and keep storing pictures?
