Exchange laptop data with Thunderbolt?

Since I have a new notebook, I would like to transfer all of my data (games, photos, etc.) from the old to my new notebook. Since the amount of files is approx. 200-300 gb, the data transfer via Wi-Fi / Wi-Fi turned out to be very slow, which I temporarily canceled.

The alternative would be that I exchange the data with 2 network cables via the wireless router. However, I have seen that both of my laptops have a port with a lightning bolt on it. According to my research, this should be an input for Thunderbolt.

Now to my question: What would you recommend… Is a connection via the router fast enough and problem-free or can I simply use a Thunderbolt cable for example? Eg. Buy from Apple and connect my two (HP) laptops and exchange data?

You could also use a LAN cable and connect the two devices.
With GigaBit LAN this should also be quite fast.
A Thunderbolt cable costs a few euro.

I would definitely use the LAN cable option

Is the most stable and therefore safest.

1Gbit, which the network cards give, means 120MByte / sec and this is achieved in practice with large amounts of data.
This means about 10 seconds per GB with large amounts of data, the smaller the files and the more files there are, it can sometimes take ten times as long…

At 300gb that would mean between 50 and 500 minutes, right? And LAN cables are network cables right? I have two such cables with ' Cat 5e ''

So connect both laptops with a LAN cable without a router? My cable says CAT 5e, what does a GigaBit LAN look like or what should be written on the cable?

Yes, that's about it
It is also due to the hard drives in the notebooks. Everything matters
Definitely faster and more stable than WLAN

Cat5e is completely sufficient

And yes, LAN cable = network cable and vice versa

That should be enough.

Hmm 3-4 hours (180-240 min) would be too long for me and games have lots of individual smaller files… Do you also know whether I can simply connect both laptops with a Thunderbolt cable and exchange data directly?

Well, if you don't have time… I can't help it

You can also just take a CrossOver cable and connect the notebooks directly to each other, maybe it'll be faster

I have no idea whether the network brother works via Thunderbolt with two notebooks and just to try it out wouldn't be worth 30 euro or more, what a good Thunderbolt cable would cost
