What to look for with an external hard drive?

Am looking for an external HDD hard drive 1 TB. My hard drive in the laptop reaches its limits, so I thought I would buy an external HDD hard drive 1 TB. There are many different HDD hard drives on the Internet, so you don't know which one to take. Do you know what to look for or can you recommend an external hard drive? I need the hard drive to primarily make files or programs, be it games or programs for university.

If you still want to install programs / games on it, I would recommend an SSD instead of an HDD. Read / write speed is a lot faster, but more expensive.

They all work. Just have to min. Have USB 3.0. Ev. An SSD would also be worth considering.

One should pay attention to the storage space (of course.) And the reading and writing speed

You should note the following things

The speed of HDD's is given in rpm, a good HDD should have a value of 7200 (the more the better).
The hard drive should be powered via a USB port so that you don't need an extra socket
In general, you could say there are no HDDs that are not suitable for games and programs, only those that are suitable for even more.

That was the main point.

Thank you for your answer. I checked the Internet and found two hard drives, one from WD and the other from Intenso, but it has 5200 rpm and the WD has not given any information about how much rpm it has. https://www.bueromarkt-ag.de/festplatte_intenso_memory_case_schwarz,p-6021560,l-google-css,pd-b2c.html and the other https://www.saturn.de/...83222.html, which would you rather take?

You should find out which manufacturer makes the plates that fail the least quickly: https://www.backblaze.com/blog/hard-drive-reliability-update-september-2014/

Since I've only heard good things about WD from friends and family, I would take the WD from them.
