Can I also connect an external hard drive to my laptop to expand the storage capacity, and if so, simply to the USB input?
Yes, you can simply connect an external hard drive with a USB cable!
If the external hard drive and the notebook have USB, then yes.
It's just not suitable for installations, but primarily for outsourcing data.
Yep, there are cases for external HDD if it was not a direct external one. There's a USB plug and it can be easily connected to the computer.
Attention: long access times.
Yes, you can do it. External hard drives are usually connected via USB.
It's a bit impractical for mobile use.
On the contrary, I find it very practical for mobile use.
Well, something else to take with you.
