Hi guys, theoretical question here: I currently mine Z-Cash with two NVIDIA GTX 1070 cards and leave my desktop rig running 24/7. I have several HD's lying around and would like to support the SJCX network as well, plus make a little profit with my spare storage space. My thinking is that while the z-cash mining is taxing on the GPU's and the power supply (650 watts), mining storj coin should only really be taxing on the external HD and minimally on the PSU to power the USB device. CPU is an i7 4770K, MB an MSI G45 gaming with 16GB DDR3. Would be using USB 3.0 external HD vs SSD.
Is it possible, is it recommendable, and have you tried doing it yourself? In theory would either mining process slow down/impair the other? Am I not accounting for overlapping taxation on the CPU, RAM, or MB?
