Which is better for an emergency fund, sweep-in FD or savings account?

Experts suggest using both options rather than relying entirely on a savings account or sweep-in FD. Keep some money in the savings account for immediate needs, while surplus funds can be moved into a sweep-in FD. Savings balances may lose real value to inflation, whereas sweep-in FDs can earn around 6-7% while retaining liquidity when funds are required.
