You should open at least two savings accounts. One should be a "hub" for your money that has high transfer limits and fast transfer times. I recommend using Discover Online Savings Account as one of your hub accounts. It has an incoming transfer limit up to $250,000 per 30-day rolling period and an outgoing transfer limit up to $250,000 per 30-day rolling period, per registered Account Center owner (limits are subject to a combined incoming/outgoing limit of up to $300,000 per 30-day rolling period). Compare that to most banks that have a limit of $5,000 or $10,000 per day. The second one should be a bank account that earns you the best interest rate for your money. That could be any of the high-yield savings accounts listed here that best fits your needs.
