How do I best play the data from my old laptop to a new laptop?
USB stick or external hard drive take. Have a backup then.
You could either pull it to an external hard drive or a USB flash drive and transfer it from there to your new PC (would be the easiest), or you'll use cloud services (assuming you agree with the privacy rules, as companies do usually have relatively lax rules). Disadvantage with the latter would be that depending on the Internet connection takes longer and depending on the service of you to available (free) memory can be too low.
Log in both devices in the same network and copy the data via router and WLAN
Then I would rather take a stick or a hard disk.
I'm just considering whether I have a stick that has so much capacity. I still have an older hdd. On the go 250 gb
The HDD can use the course, even if the speed is not necessarily the Burner. If 250GB is not enough, you could distribute the data to several hard drives or sticks or transfer the data one after the other (after transferring the stick or the HDD delete and the rest on it)
