Advice For Streaming Hard Drive

Since I’ve had it twice now whilst streaming that my internal hard drives ran out of space and stopped the record (but not the stream altogether) whilst I was live, thus losing the original recording file entirely, I have decided that it might be best for me to have my streams recorded to an external drive with a good amount of storage (leaning to 4TB at the least).

I stream 1080p/60fps for starters and my streams typically last around 4hrs (2hrs at the minimum), so the recording files can get pretty hefty - sometimes can be around 50GB. Back when I used 720p/30fps, it generally wouldn’t break 6GB, but of course the quality really shows in comparison.

So then, here are my question for the advice I’m looking for:

• I was thinking of just recording the stream directly to the external (two of the friends I asked agreed that was the better option), or would people recommend I record to my internal and then transfer to my external? If it helps, my internal drives are 2TB Kingston SNV2S/2000G SSD (PCIe Gen4) NVMe M.2 SSD AND 4TB (4TBx1) SATA-III 6.0Gb/s 64MB Cache 5400RPM HDD

• Would anyone recommend I change my quality and not do 1080p/60fps? I’m willing to compromise on the specs, but I’d really prefer not to do 720p/30fps again. So if there’s a recommendation for changing, such as 1080p/30fps, I’m open to suggestions. I’m perfectly fine with the large files, it’s just easy to run out of space, ya know.

• Most important of the questions: which external drives would people recommend the most for recording directly to the external? If I just record to my internal and then transfer to the external, that obviously doesn’t really matter too much)

EDIT: I even just had the idea of using a docking station, as I do believe I have one. Or does that seem like a stupid idea? If people think that’s a good idea, any recommendations for a drive with that?

TL;DR - What external drive is recommended to stream directly on with 1080p/60fps recordings?

Much appreciate!
