And before you say you'll never need that:
HDTV 1080i is 1,080 scan lines x 1,920 pixels/line = 2,073,600 pixels x
24-bits/pixel in YUV format / 8 bits/byte = 6,220,800 bytes/frame x ~25
frames/sec = 155,520,000 bytes/sec x 60 sec/min x 60 min/hour =

 559,872,000,000 bytes for 1 hour HDTV quality home movie of your
daughters birthday party recorded on your brand-spankin'-new HD home
camcorder stored uncompressed for editing. That's 560 gigabytes.

Other than that, you don't.
