According to a forum post at GoPro, you are allowed to plug in up to 256 GB:

The Gopro Max is a 360° hobby camera that was developed for hobbyists and primarily videos, in order to bring 360° videos into the price range.
Writing your own software for it could still be very tricky, depending on your previous knowledge. For the Hero cameras, there is software from Rocksteady for stabilised videos from the 4th or 5th generation (before Hypersmoothe).
So I would imagine that there could be a third party software for the MAX somewhere, possibly with HDR mode. The best place to look is Github (https://github.com/). Or ask Google.
Hope you find something and happy new year 😊
The supplier (I think it is intercycle) could not meet the deadline and obviously communicated very badly. The date has not yet been adjusted, but digitec support told me on Friday that the GoPro will be shipped from the middle of the week... No guarantee... ¯\_(ツ)_/¯
Dear Peter
Without the one-year subscription, you would have paid 539 CHF at GoPro for the camera alone.
GoPro seems to want to push the subscriptions and therefore offers a bundle.
The bundle includes a Sandisk Extreme microSD A2 incl. SD adapter (microSDXC, 64GB, U3, UHS-I) (~22 CHF) as well as the hard case and the subscription.
But also remember: if you buy it at Digitec, you can send the camera to Digitec in case of a warranty claim.
Whether that's worth enough to you, you have to decide for yourself.
As soon as the GoPro promo is over, the camera will be cheaper here.
