Assuming that the 1 GB/min figure is because you're saving broadband (back of the envelope math assuming you have two Utah arrays with 32 bits/sample at 30 kHz), you can get enormous space savings with compression. Field potentials are highly correlated across channels, as you no doubt know. Depending on your amplifier you may be able to pack everything into 16 bits/sample too.
