I’ve found that for single person purposes, a RAID array is unnecessary. I just buy beefy 8TB drives. If it dies, just download any recent torrents again or pull a backup

I’ve never had a problem side loading an entire folder into Firefox. Maybe it was an addon rather than extension though?

The point of a digital signature is to announce that you made this document, as it exists at the time of writing. Once a change is made it should no longer identify as signed.

Most institutions don’t use this functionality, despite the usefulness of it. At present, I’d recommend using it for publicly distributed files to protect against bad actors publishing a document that pretends to be yours.

As for legally binding, ask a lawyer. Generally, things are legally binding if they’re signed by all parties. The specifics get funky, but a digital signature is a solid step for announcing that you did this thing at this datetime and a judge should recognize that if it comes down to it. Bonus points if all parties attach their digital signatures.

They do more than just tie hard drives together with a string. They build custom server hardware, maintain data center infrastructure including cooling and networking, pay their employees (the biggest cost), and all the overhead of running a business.

20% increase in one go is rather normal. Business tend to do one big price increase instead of constant small ones because our brains don’t see them billing efficiently relative to their costs, they see only a bunch of tiny price increases.
