I know this isnt difficult, but I'm getting stuck:

"An 850 M-byte hard disk is used to store digital voice data. Suppose that voice signal is sampled at 8 ksamples/sec and the encoded digital data is to have an average SNR of at least 30 dB. How many minutes of voice conversation can be stored on the hard disk?"

Any help is appreciated, thanks.
