Which external hard drive is the best (1tb / 70 euro)?

I will soon get a xiaomi mi 9 that has "only" 128 GB of storage space that you can't expand but I have the 150gb of what I need 30gb really need to use pictures are just pictures of 8 years smartphone use I would like to secure without fear that they will be lost that is the hard drive may not break against during normal use and I'm super impatient that means it should be as fast as possible and support usbc 3.0 and 2.0 and I just want to hang the phone without me thanks for the laptop schon

Use a laptop, that works better

Why do you need 150 GB of data on your smartphone?

There are all things on it and I can delete but the next day everything is back there I've also identified the Cloud cloud ka what's up lately synonymous n Video made it wanted to watch the colors fluttering everywhere around the other half of the display was black a short time later what the video gone the same with the photo I had made is a Samsung a5 (2017) … I sat there for a day and deleted pictures…

Well with the laptop I definitely do not have a Dell is a bit older and still need a hard disk…

Should your phone reset to factory settings.

And then you do not need a hard disk, but just get a micro SD card.

I can't clean it in the Xiaomi mi 9 …
