Disk Activity Question

Temporary files may get created.

 

How many threads are you going to start with these questions? As I said before in the other thread, you need to stop obsessing about Activity Monitor. It's absolutely normal if data is being read but not written, written but not read, both read and written, neither read nor written, and all of the above at different rates and different amounts. There is no need to watch that reading unless you have a specific problem you're troubleshooting. You'll enjoy your Mac a lot more if you forget about Activity Monitor and just use your Mac for web surfing, watching videos, etc.

 

80% of Disk activity on your OS drive is 4K writes to the Hard Drive.

 

It's normal. You don't have to try to figure out every time your computer reads/writes the hard drive, or how much is read/written. Just let it do the job. You don't drive your car with the hood open, counting all the times your pistons go up and down or how many times your crankshaft turns, do you?

 

Yes. And it wasn't your computer hardware, it was Skype software. Most of the glitches you will run into while computing are software based. Not all, but most. If a restart or re-launch fixes it you should be feeling great as sometimes it is not that easy.
