@miriam98 - I didn’t know that you could do that. I assume that he needed at least a little space on a floppy disk or something.
Anyway, that approach would hardly be practical nowadays, with prices for hard drives, memory and everything else plummeting. I do agree that RAM is faster, especially when you add in the caching.
Personally, I prefer non volatile flash memory to store a lot of my data. It’s fast, and not as susceptible to corruption and easy deletion as RAM is. Plus, flash drives have gotten much bigger in size, so I can use them to do an easy backup of my computer.
