The Sony M series 100 MB/S write cards work fine with all-i, but IIRC they can't dual record to 2 cards. I have 6 of them and have used them for years.

I've been using this one: Sony Memory Card 128GB, UHS-II SD, CL10, U3, Max R260MB/s, W100MB/s

It works well for all bit rates, etc., the only caveat being is it won't allow dual simultaneous recording at the high rates. But if you're not recording redundantly, it works great.

this card, cheapest one around that I have found from what I would call a reputable company. Works on all recording modes and I personally or my friend who got the same card after I recommended it to him have never had any problems with it.
