On the Sony A6000 there really is no best sd memory card, they all perform very close to the same in terms of write speeds. There is an internal bus speed bottleneck in the A6000 slowing down the write speed to the card.
What else is interesting is when shooting JPEG only, write speeds slow to a 10-12MB/s range which makes me think it’s capping out because of a single threaded processing. Most of the Sony cameras we’ve tested like the Sony A7s and the Sony A7r give very similar results. However, the Fuji X100T is the complete opposite.
Recommended Memory Cards A6000
From out tests with various Sony cameras we’ve learned a lot about how Sony cameras handle and like Sd memory cards. Sony cameras can be picky, so we’ve put together a list of the top three memory cards for the Sony A6000.
Best SD Cards For The A6000
Because Sony cameras are very picky, I’m only going to list you the card I recommend from my years of experience doing this.
Sony 64GB U3 UHS-I
You can trust any Sony card to work great in the A6000. There are a few different models floating around out there, but this is the latest UHS-I SD card by Sony. – Amazon
Sandisk Extreme Pro 64GB U3 UHS-I
For Sony shooters, Sandisk is my second choice. Any of there Extreme cards will work great. However, I would avoid the Ultra card. It’s very slow.
So the best Sandisk cards will be the Sandisk Extreme Pro, Sandisk Plus, and Sandisk Extreme. But I’ll list the Sandisk Extreme Pro since it’s the all around better performer. – Amazon
Sandisk Extreme Plus 64GB UHS-I
Not as fast as the Sandisk Extreme Pro, but because of the slower speeds of the Sony A600, it shouldn’t matter. These cards work very well and you can often find great sales on them. – Amazon
We’ve found that typically the Sony A6000 doesn’t like a few memory cards. Samsung, sometimes Transcend, and sometimes PNY. All other cards have been working great, but these recommendation above are still going to be your best results.
Sony A6000 Speeds Stats
Shoots at a burst speed of 11fps and its file sizes are roughly around 25MB.
Burst Speeds: 11fps
To maintain a burst of 11 fps that’s some crazy bandwidth. 11fps x 25MB = 275MB/s.
With the buffer you can shoot 49 Jpeg shots, or 21 Raw. Meaning the buffer has something like 512MB of memory.
Your card speed doesn’t necessarily affect your burst performance. Just when you’re done bursting it will take a long time to write those files to your card.
With something like the SanDisk Extreme Pro 95MB/sec card, you’ll wait about 14 second for the files to write from the buffer to your card.
Do You Need A UHS-II Card
This camera only requires UHS-I cards and cannot take any advantage of a UHS-II card. So if you’re looking to improve your burst write speeds this camera will not take advantage of UHS-II like a proper UHS-II compatible camera will.
Bottom line is, purchasing a UHS-II memory card for the Sony A6000 will yield you no speed improvements.
SDXC VS SDHC
If you want to buy a 32GB version of any of these cards, they perform the same. However, 32GB cards and smaller are SDHC and are formatted Fat32 instead of exFat64.
Do you need an SDXC card for the Sony A6000? Yes, the A6000 now shoots XAVC S footage so you need an SDXC card to shoot in this format. If you don’t shoot video, then it won’t matter.
Side note: You won’t be able to format an SDHC card to exFat64 and be able to record to the XAVC video codec.
Update: Sony updated some of their cameras with firmware to support SDHC with XAVC S video. You’ll have to check if the Sony A6000 firmware included this update.
Memory Card Speed Tests Conclusions
We’ve been getting pretty consistent results with these cards. Usually the Kingston and Sandisk Extreme Pro are the fastest cards. We’ve always bought the Sandisk Extreme Pro cards because they last for years and it saves you from having to upgrade in the near future.
When it comes to performance, you don’t really see or notice any speed difference between any of these cards even with burst write speeds. You will however notice it on older cards. Mainly when you go to view playback.
