The Panasonic G9 has 2 x SD memory card slots that both support UHS-II cards. Don’t worry if you don’t know what this is, we’ll get to it in a second.
The G9 is a fantastic camera for the money, since it features 4K video recording and very fast continuous burst shooting, which means you shouldn’t just get the cheapest card available unless you want problems in the future.
Speed Class of SD Cards
|Class||Min. Speed||Our opinion|
|Class 4||4MB/s||Too slow for most modern cameras. Skip it.|
|Class 6||6MB/s||A little bit better but unless you take 3 pictures a year, skip it.|
|Class 10||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video.|
|U1 (UHS)||10MB/s||Good enough for most cameras with 20+ megapixels and Full HD video|
|U3 (UHS)||30MB/s||Perfect for fast burst cameras, Full HD at 60fps and 4K video|
As we mentioned above, the Panasonic G9 supports UHS-II cards. This means you should spend a little more money to get a UHS-II card if you want the fastest possible results. This applies for both usage in the camera, as well as faster transferring files to your computer (if using a memory card reader).
If you’re going to record lots of 4K videos or shoot wildlife and often use burst shooting, you’ll want UHS-II. Otherwise, UHS-I is still very fast and perfectly usable, even for 4K videos.
Go with a 32GB or 64GB sized card, and buy a couple of these if you need lots of storage. It’s better than buying one huge card because you risk losing all of your shots if that 1 specific card fails.
These are the best 3 SDHC/SDXC memory cards you can get:
- SanDisk Extreme Pro 300MB/s UHS-II U3
- SanDisk Extreme Pro 95MB/s UHS-I U3
- Transcend R95/W60MB/s UHS-I U3
SanDisk Extreme Pro 300MB/s UHS-II U3
The SanDisk Extreme Pro 300MB/s UHS-II U3 is a UHS-II card that is worth every dollar. SanDisk has been in the memory card game for a very long time, and is the go-to brand when you’re looking for a reliable card.
It’s ideal for 4K videos, let alone Full HD, and burst shooting. Writing speeds can reach up to 230MB/s, although the Panasonic G9 has limitations, and it will reach around 100MB/s in the actual camera. Still enough for anything you will do.
SanDisk Extreme Pro 95MB/s UHS-I U3
The SanDisk 64GB Extreme Pro 32GB U3 is our favorite UHS-I card, seeing as it’s inexpensive and provides writing and reading speeds near 90MB/s.
The speed makes it perfect for whatever you’re doing; fast bursts with large megapixel cameras, 4K video, let alone Full HD at 60fps. It comes in 16GB, 32GB, 64GB, 128GB and 256GB sizes. Yes, it is UHS-I, but it’s also U3, which means it can record 4K videos with no trouble. Cheap, extremely popular and works great!
These two models are literally the best on the market, and have been for some time.
Transcend R95/W60MB/s UHS-I U3
The most affordable on our list, yet still UHS-I, is the Transcend 64GB UHS-I U3. In terms of reading speed it goes up to 95MB/s, while for writing the maximum is 60MB/s.
Transcend gives you the option of downloading their free image recovery program and they both work pretty good in most cases. It comes in 64GB, 128GB and 256GB sizes.
However, we really recommend you to get any of the Sandisk cards, this one is just if you’re on a super tight budget.

What Brands are the Best?
Your photographs and videos are stored on a memory card, so you should definitely not try to save any money here by buying from unknown, cheap brands. While you save a few bucks, you probably won’t even get the advertised speeds, and are at a bigger risk of losing your shots.
We see too many beginners choosing the cheap route here, but until you transfer your shots to a computer/online, this is where they’re stored at. You want the memory card to be the most reliable piece of your equipment!
