What is considered as high memory for a USB flash drive?

What is considered as a high memory/ large storage space for a USB Flash drive? The ones I have is 8GB or 16GB, and I think that's not enough space for long term use.
I needed to use it mostly for files, like music, photos or Word documents. What is a decent or good amount of memory for a USB flash drive? How many GB is high memory?

I have tried plugging an HDMI cord into both my tv and computer, but all I can manage to do is screen mirror my laptop onto m tv. I want to use share screens on Skype from my computer so that my friends can watch me play video games on my Nintendo Switch which will be on the tv. Any ideas?

Is there anywhere I can install a DVD drive into my laptop?

I got the Lenovo 320 IdeaPad white. The picture of it was misleading as it has a button on the DVD drive to open it. I got it today and there's no button I can't open it and I called them up according to them I don't even have a dvd drive. So why would they make one that looks like one and advertise a picture of a button on the side of it. Is there anyway I can install a DVD drive into it?
Or would I be able to return it even though I've turned it on?

What's wrong with my laptop? - 1

I have a Lenovo laptop that I bought barely an year ago. Everything was fine until now, I was using it, doing regular stuff and then it just shut down all of a sudden. Now, every time when I press the power button, nothing shows up on the screen, but the light on the button turns on and off repeatedly and makes a clicking noise, then it stops at some point. I kept the laptop on charge for every time I turned it on, if it means something. So what's the problem? What can I do to fix it?
