I recently got some SSDs, and decided to use one of them (a 256G model) to boot from.  I want the change to be undetectable, in that from a user perspective, nothing seems different, just faster.


I would:

That is the bit I'm not sure how to do so the change is mostly undetectable.


I once heard a speaker who worked as a Linux system administrator on Wall Street state:

"You should be able to pick any computer at random, throw it out a 7th story window, and have a replacement in operation within 2 hours".


The key is disaster preparedness and disaster recovery.  Expect that your computer(s) will break, and prepare for it with backups.  Verify your backups by doing recoveries and comparing the source against the recovery.  [1] is dated, but will get you thinking in the right direction.  A related technique is disk imaging.  Another is archiving. Learn them all.

I do back up my entire drive weekly. NAS too. However, I recently looked around for another 2T drive to implement two-level backups and didn't have one. Can't afford one right now either.

Learn how to write shell scripts (or Perl, Python, etc.), so that you can automate repetitive tasks and get consistent results.

I write shell scripts (sh, occasionally bash) for that purpose.

Do not be afraid to spend money on a spare computer, spare parts, and bigger HDD's.

It's not that I'm afraid, it's that I'd rather keep the car, keep us fed, etc. than do that. Not everyone has enough disposable income to do things the recommended way.

Keep records of anything and everything that matters.

I have a log file where I note important stuff.
