I want to convert my 6+ year old, self-built, AMD-based 'gaming PC' into an audio production PC. I've recently started recording on it, with Reaper as my DAW and Scarlett 2i4 as my interface, and she struggles a bit. Right now, it's only got a single, 500GB HDD @ 7200RPM. From what little I've learned about "audio pc's", this is probably my biggest bottleneck as far as system performance. So, it's probably where I should start. But, that's where I'm a little lost. I don't know what I need, nor where to store things once I get some new/better drives in place. I'd like to add something like Komplete, add an external midi controller, etc. Also planning to buy one-off plug-ins and stuff too. I know I should probably get a smaller SDD for my OS, DAW, and other software, but I'm not sure what I should do for sample libraries, plug-ins, general storage, etc. Any advice here would be greatly appreciated.
