optical media is low-key underrated tbh.
A rewritable BD-RE is 25GB, and you can get a spindle of 10 (250GB) for about the same price as most cheap 64GB flash drive these days.
"But quad, burning a disc is so slow"
And so what? A blu-ray writes at around 4 MB/s, and every single writer I've seen does 2X speed. Most bargain bin flash drives I've encountered don't go much faster anyways. If you want a fast flash drive they definitely cost more than optical media.
The main disadvantage is of course that devices need to have an optical drive, and if you plan to rewrite the media 100 times, flash storage is likely a better idea.
But in an age of overpriced flash storage, a cheap plastic disc can be a godsend
