AngelbirdAV PRO SD 128GB UHS-II SDXC Internal Memory Card for Cameras, Up to 260MB/s Write Speed, Up to 300MB/s Read Speed

The card was handling 8-bit on the gh5 with no issues, but after a few days of light use at 10-bit the card completely dies. Won't read on any of my compatible devices.

Faster than the Delkin V90s and better performance. Has reliability issues though when it comes to recording video on the Panasonic Lumix GH5. At first I wasn't experiencing the same errors as I do with the Delkin v90, which typically reports that the camera cannot record video because of the write speed of the card when switching from 8bit VFR to 10bit modes. After a few weeks of use, the Angelbird card is having very similar issues as the Delkin cards. Still this card, writes faster than the Delkins for certain.

Awesome and speedy, can't yet judge its reliability but seems functioning great and fast. Build quality is somewhat in the upper level than my sandisk, prograde and sony.Time will tell and i will update my review semi annually to let you know how its keeping up with my use.

I watched many YouTube videos trying to find the best SD card for the GH5's high demand (400 mb per second).I bought this card and I am very satisfied.

so far they are doing the job. If anything changes I'll change my vote or edit the review

As advertised.

Purchased mine from Adorama and it did not work as advertised. The manufacturer was quick to respond although a replacement will likely take weeks.10/25/18 Update: The manufacturer sent a replacement, which arrived in a few days, however the replacement card also failed to write 400mbps 10bit All-intra to the GH5 for longer than 20 seconds. Anyone planning to purchase a GH5 for 400mbps/10bit recording should do so with the understanding that finding a card that is capable of the required write speeds can take some time. I've already invested a month into getting my GH5 ready for production and I am still at square one.

It failed after light use. On a job. Shooting raw photos.
