Just catching up on this thread and i gotta say, i actually disagree a bit on the SanDisk recommendation. Dont get me wrong, they are fine for some stuff, but i have seen way too many of those plastic casings literally fall apart in the slot lately. If youre dropping serious cash on an FX2, you really want something that isnt gonna fail when things get hot or if you drop it. Basically, if reliability is the main goal, i would look at these instead:

• Sony TOUGH-G series SDXC UHS-II V90 - these are built like a tank, no ribs to break off and waterproof.
• ProGrade Digital SDXC UHS-II V90 300MB/s - their sustained write speeds are super consistent for 4K. Ngl i would rather pay a bit more for the Sony Tough cards just for the peace of mind. Having a card fail mid-shoot is a total nightmare... anyway, just my two cents on it.

FX2 supports both CFexpress Type-A card and UHS-II SD card.

For CFexpress Type-A card, you can get Lexar Professional CFexpress Type A SILVER Series.

For UHS-II SD card, you can get SanDisk Extreme Pro UHS-II V90 card.

Yeah pretty much what was said about the dual slots being a huge plus for flexibility but honestly you really need to look at your specific workflow before you go out and spend a small fortune on cards because those high-end ones are still way too pricey for what they are tbh. Basically what are you planning to shoot the most? Like are you going to be doing a lot of 4K 120p in the highest bitrates or are you sticking to standard frame rates for narrative stuff because if you dont need the absolute highest end codecs you could save a lot of money by going with slower speed classes that still work for most modes. How much footage do you usually offload in a day anyway? Just want to make sure you dont overspend on speed you might not even use for your specific projects.

Honestly, those are good points about the cost and slots. Just saw this thread and wanted to add a bit of a warning about the reliability side of things tho. Even if a card says it hits a certain speed, u really gotta watch out for sustained write performance because if the card dips while youre recording a high bitrate 4K file, the whole thing could just corrupt and leave u with nothing. Basically, i would stay away from any of those super cheap generic brands u see on some sites, even if the specs look okay on paper. Its just asking for a failure at the worst possible time tbh. Also, be careful with where u buy from because fake cards are everywhere and they look identical to the real ones. Another thing is the heat factor. These FX cameras can get pretty warm and some cards handle that way better than others. If youre doing long takes, a card that throttles its speed when it gets hot is gonna cause a recording stop which is a huge pain. Just make sure whatever u pick has a solid reputation for durability and not just raw speed stats on the box, thats what im mostly worried about when choosing.
