GDAX and Gemini BTC and USD transfer times?

I would appreciate if someone could let me know, in general, how long it usually takes, and what the potential pitfalls are, when transferring BTC or USD between GDAX, Gemini and your bank.

For example, if I wanted to move Bitcoin at GDAX or Gemini to a hardware wallet, and then later move it back to the exchange, how long would those transfers usually take. And after initiating a transfer, could the Bitcoin be temporarily unavailable during some type of security review etc by the exchange? Before doing a transfer, I want to make sure that I don't lose temporary access to my Bitcoin in case I want to sell.

Another case is if I want to move Bitcoin between GDAX and Gemini. And another one is if I want to withdraw USD from either GDAX and Gemini.

I would greatly appreciate you sharing your experiences with transferring Bitcoin and USD between these exchanges and your bank.
