FireWire Hard Drives

摘要

Years ago, when Apple shipped its first Macs with 1GB hard drives, I remember asking myself, "Who would ever need that much storage?" It didn't take me long to figure out who, especially now that the 80GB drive in my PowerBook is bursting at the seams with pictures from my multimegapixel digital camera and my ever-expanding library of audio files and movies. Files and applications aren't the only things taking up precious storage space—OS X puts available disk space to work as virtual memory. My system, for example, uses 5GB as virtual memory with no applications running, and almost 9GB when running a lot of applications. This use of hard-drive space by the operating system means that your entire system can take a performance hit if you start running out of drive space.
