If you're talking about locate time, the response from when you hit PLAY, is incredibly fast. Since the ADAT HD24 puts all tracks for a song in one place on the disk, you'll hear audio
in less than 1/10th of a second. (Competing recorders may take over 2 seconds to locate the track on disk before you hear audio.) For advanced users looking for the "seek time" specification for the hard drives the HD24 uses, this will vary on a drive to drive basis. Many hard drives have a seek time of about 9mS. Seek time variance of currently-available hard drives will not have an affect on HD24 performance.
