The best memory card for a Sony A9 II videographer will not be the same as an A9 II photographer, and similarly for the A9 II hybrid shooter.
There will also be further different use cases of hybrid shooting. For example there will be users shooting different balances of video and photo.
So whichever use case suits you, we will have to go into further detail to work out what the recommended cards are capable of. Only then can we work out the right card for each use case.

Which Memory Cards Does the Sony A9 II Use?
The Sony A9 II has two memory card slots that supports the faster UHS-II SD cards.
While you can use the much slower UHS-I cards and save a bit of money, I will be recommending the UHS-II cards which will be better and more reliable for 4K video recording.
UHS-II means you can get the super fast read and write speeds to transfer and buffer, getting content on and off quick.
Best Memory Cards for the Sony A9 II to Record 4K Video
The Sony A9 II will only record 4K up to 30p, so there is no 50/60p option or 120p for that slo mo video.

Do bear in mind that all calculations are estimates. There are a lot of variables that you need to consider that can alter the length of recording.
For example, the environment, the ambient temperature can drastically reduce record times. The battery health can also play a factor.
The Other Best Memory Cards for the Sony A9 II
Sandisk is one of my preferred brands for SD cards and they have yet to fail on me in my over 10 years as a professional wedding photographer.
But there are alternative brands who produce SD cards that are just as good, if not better.
Sony for example with their Tough series are cards that should last years of use.
The build quality is of particular note, built with what looks like one plastic case as opposed to two. The design looks like it will help it to take a good bit of use.
Below is a (automatically updated) list of the bestselling UHS-II cards on Amazon for consideration:
- For prosumers and professionals shooting with MIL and cinema cameras

Finally
No Sony A9 II user should get the wrong memory card when the information is right here; either by spending more than is required on too large a capacity memory card, or just as bad, getting a card too small for your needs.
Making the mistake of getting smaller capacity cards means having to make workarounds for the bottlenecks you will encounter, and too large capacity SD cards for your needs means extra money spent that could be spent on other essential gear.
Get the right memory card the first time.
Once you have picked the best card for your requirements you will then need an SD card reader to get your data off quickly and efficiently:
