Take a look at the best memory cards for the new Sony RX10 IV.
The RX10 IV is an excellent all-around camera, perfect for traveling, wildlife, nature and pretty much anything you can think of. On top of that, you can also record videos in 4K, or Full HD at 120p.
All of these features require a good, reliable memory card. Wildlife (burst shooting) and 4K are both quite heavy on a memory card due to so much information being written continuously.
We looked at all memory cards available and selected the 3 that give you the most performance for your money.
Speed Class of SD Cards
|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|
The Sony RX10 IV has 1 x SD memory card slot that supports UHS-I cards. These are very inexpensive, and the most popular type for almost every camera available.
Looking at the table above, you’ll want to get a UHS-I with a rating of at least U1 (10MB/s minimum speed). U3 would be the best, and it’s really just a few dollars more. The reason is because anything slower is not enough for 4K videos, or taking a few pictures in burst mode.
These are the best 3 SDHC/SDXC memory cards you can get:
- SanDisk Extreme Pro 95MB/s UHS-I U3
- Lexar Professional 95MB/s UHS-I U3
- Transcend R95/W60MB/s UHS-I U3
SanDisk Extreme Pro 95MB/s UHS-I U3
The SanDisk 64GB Extreme Pro 32GB U3 is our favorite card, seeing as it’s inexpensive and provides writing and reading speeds near 90MB/s. It’s a card we recommend for almost every camera that costs under $2000, because of it’s great price to performance ratio. You get one of these and it’s yours for years.
The speed makes it perfect for whatever you’re doing; fast bursts with large megapixel cameras, 4K video, let alone Full HD. It comes in 16GB, 32GB, 64GB, 128GB and 256GB sizes. It is hands down the best choice for the Sony RX10 IV.
Lexar Professional 95MB/s UHS-I U3
The Lexar Professional 32GB U3 95MB/s is cheaper than the model above, and reaches the same reading speed yet falls a bit short in the writing department. While the minimum for U3 cards is always 30MB/s, this Lexar series reaches around 60MB/s.
It won’t be as fast as the Sandisk above (even though it’s fast), but unless you’ll be using the burst mode often or record in 4K, you won’t notice it. However, since memory card prices fluctuate a lot, if the Sandisk above is cheaper then definitely go for it.
Lexar also gives you the code to download their Imaging Rescue software. It comes in 16GB, 32GB, 64GB and 128GB sizes.
Transcend R95/W60MB/s UHS-I U3
The most affordable on our list, yet still UHS-I U3, 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 just like Lexar above.
Transcend also 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.

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!
