Recommend External Hard Drive?

I recently started playing games again. I used to play games that were all under 70GB and it was all fine. But, I've recently discovered some "newer" games that were a little heavy and my computer doesn’t have enough storage. I want to be able to play Baldur’s Gate 3 and not have to switch to my other device.

Unfortunately, I fall under the stigma of not being a very tech-savvy female. Somebody used to set it up for me, but we’re not in contact anymore. A friend recommended I get an external hard drive, but I don’t know what to pick.

Here are my specs if it helps:
OP system: Windows 10 Pro 64-bit (10.0, Build 19045)
Processor: AMD Ryzen 5 2600 Six-Core Processor
Memory: 16384MB RAM
GPU: NVIDIA GeForce GTX 1650 SUPER

Please, be kind. Thank you.
