If RAM is cheap, why don't we load everything to RAM and run it from there?

RAM is cheap, and much faster than SSDs. It's just volatile. So why don't computers have a LOT of RAM, and on power up, load everything to the RAM from the hard drive/SSD and just run everything from there, assuming there's no real need to persist…

How long would it take to transfer 1TB over USB 2.0?

This might be a completely stupid question because it is conceivably highly dependent on the respective disk speeds. But I am thinking that there is a speed cap that is specific to USB 2.0 that would by itself define a lower limit. How long would it…

Why do HDDs mostly have the same speed as 5400, 7200, 10000 RPM?

Why do hard disk drives mostly have the same speed? They are mostly 5400, 7200, 10000 RPM. Why not 6000 or 8000? Is there any reason or benefit for having those speeds?
