How risky it is to run Ubuntu from a flash drive?

//
I just installed Ubuntu on my 16 GB flash drive. I occasionally use it to edit documents or use the terminal to SSH to my server online, edit server files, and download online files to put on my server. Is my Ubuntu installation something that would cause my drive to wear out fast? There’s hardly any write activity during boot and shutdown. How long should I expect my drive to last?

Unfortunately, there’s no really clear answer to that question. To be honest, I don’t how much Ubuntu is writing to the installed drive, though my guess is probably not a lot. As long as you’re not memory constrained on the machine that you’re using it on, there’s a good chance that it’s mostly reading. When you become memory constrained, Ubuntu may fire up a paging file, which could cause a lot of write activity. But my guess is that Ubuntu itself isn’t doing a whole lot of writing.

I am a bit concerned about the flash drive, but it actually makes sense. Let me explain.
