- You guessed it... Drive speed is the biggest determining factor in image
- quality when recording video images to disk. Since the current level of
- technology in today's hard drives cannot handle full, uncompressed
- images, all these non-linear systems have to use image compression. The
- slower the drive is, the more compressed the files have to be. When
- faster drives come out, they can use lower compression ratios, and get
- better image quality.
