I own a Sony A7 III which accepts dual SD cards - one slot is UHS-II and the other is only UHS-I and memory stick (does anyone still use memory stick?). This package seemed like a great bang for the buck to fill both those cards and offers a nice performance upgrade over the older micro SD card I had been using.
In a Black Magic disk speed test on the built-in reader in an iMac Pro I topped out around 98 MB/s write speeds, falling quite short of the advertised 120MB/s, but it's still a significant upgrade (about 3x the speed of my previous card). The read speeds topped out around 247MB/s, so quite close to the advertised speed. Nonetheless, this card is more than fast enough for my use and significantly improves the wait time for saving burst photos. I haven't noticed any problems recording 4K 30fps video.
A note for Sony A7 III users:
If you use two cards simultaneously, your performance will be capped at the speed of the slower slot, unfortunately. In my case I'm shooting RAW to slot 1 and JPG to slot 2, so that way I have some kind of backup if the RAW card dies or something gets deleted, but writing JPGs to slot 2 doesn't slow down the writes of RAW files to the faster card as much.
