Building a fast all-SSD NAS (on a budget)
I edit videos non-stop nowadays. In a former life, I had a 2 TB backup volume and that stored my entire digital life—all my photos, family video clips, and every bit of code and text I'd ever written.
Video is a different beast, entirely.
Every minute of 4K ProRes LT footage (which is a very lightweight format, compared to RAW) is 3 GB of space. A typical video I produce has between 30-60 minutes of raw footage (which brings the total project size up to around 100-200 GB).
