192KHz * 24bit * 48tracks = 192000 x 24 x 48 = 22184000 = 222Mbit/s = 28Mbyte/s
which is very slow speed requirement for current hard disk technology.
so it should not be a problem.
for a 60G HD, recording time = 60000/28 = 2142 seconds = 35 minute.
which should be more than enough for realtime recording in studio for buffering.
