[Bitcoin Client Software and Version Number:]

Bitcoin Client Software and Version Number: Bitcoin Core v0.19.1 (64-bit)

Operating System: Yosemite 10.10.5

System Hardware Specs: 2009 Macbook Pro. ~30GB hard drive space free. 8GB RAM

Description of Problem: Trying to transfer a small amount of BTC I received in 2011 to my new Ledger Nano. I have confirmed the coin amount is still in the wallet. I started to let Bitcoin Core sync, but I don't have enough space to transfer the entire thing. I tried 2 test transfers, but cancelled after days of them being stuck. The first transaction had way too low a transfer fee (my mistake) and the 2nd I thought I had an accurate transfer rate (0.00103 BTC/kilobyte - a few days ago) but it was still stuck for several days before I cancelled the transaction.

Summary Questions:
        - What is the best method for me to transfer this old BTC to my new cold storage wallet/address?
        - Do I need to sync all of the blockchain before sending a transaction?
        - If yes to the above, can I "switch" the blockchain download/sync to an external SSD? or "switch" to make it start syncing in pruned mode?

Any specific steps would be greatly appreciated! Thank you.
