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.
