Dear Hello. I received my futurebit appolo 2 and I have a question how long does it take to synchronize the BTC database for solo mining? What flash drive capacity and flash drive class does futurebit support? I installed a 512gb sandisc class 3 4k instead of the native flash drive, but futurebit does not start with it. I created an image for it using belendaitcher, I installed the native one and everything started.
