My main recordings folder is 175 GB, for a little over ten years worth of recordings. That’s not really all that much - consider how much a terabyte hard drive costs these days, it’s a trivial expense. Even when you include the various backups I keep (definitely don’t want a crash to take all that out).
My GPU’s reasonably hefty, an RTX 4090 with 24GB of VRAM. But AI is a rapidly changing technology right now so who knows what the next six months will bring. Someone might come out with an awesome lightweight model, someone might announce they’re going to be selling a cheap AI-specific card. My view has always been “save the data now because you can’t save it later if you didn’t save it now. You can process it any time.”
Perhaps in absolute terms.
