The new adapters are certainly expensive, almost four times as fast transfer speed, it is me but worth it.
Of course, this is always bad, depending on the housing situation, there are certainly better, but also worse results possible.
In past practice test for a few days, there were no crashes and speed has always been stable.
From me therefore a clear recommendation!
