This supposedly is the newer model of the Sandisk Ultra series. It claims to deliver "up to" 120MB speeds which when compared to the previous model, it's about 20MB faster. (120MB vs 100MB not a big difference). I cant compare the two since I only have the newer model.
Anyways using the benchmark application, the read speed I got was around 90MB/s. Which is great but less than advertised. Ironically though, if you look at other reviewers with "Sandisk Extreme cards up to 170MB", they are only getting about the same read speed as this card does. (Unless theirs are counterfeits.)
In my real life testing, it took about 10 minutes to transfer a 6.5GB file from my laptop to this SD card. Compare that to my old Sandisk USB stick, this SD card is light years ahead! Another good thing about this sd card is that the performance is sustained.
On the other hand, the write speed would be too slow for filming in 4K. I recommend you to spend extra on cards with faster write speeds if filming is your use primary case etc...
Using the Lumix DSLR alongside this SD card is not a problem! Everything runs smooth as it should, just don't expect to film in 4k as I've said, the write speeds are too slow for that.
All in all, I'm somewhat satisfied with this purchase. It's cheap. Offers reliable read speed and is good enough for my purpose. It's also sold by Amazon and not by other potentially fake sellers so that's assuring :)
