Best SD Cards In-Camera Comparison | Sony A6100

  • June 1, 2020
  • AGriffin

We tested 39 SD memory cards in the Sony A6100 to find the best and fastest cards.

Here are the top cards we recommend for the Sony A6100 as well as a benchmark chart and some cool specs that you won’t find anywhere else.

 

Best Memory Cards Sony A6100

It looks like Sony is keeping the A6100 a little bit more consumer-focused with the way memory cards are performing. It’s not using UHS-II cards yet and UHS-I speeds are still fairly slow compared to what some of Sony’s more expensive cameras are doing.

When buying cards stick with a minimum speed class of U3 if you need to shoot 4k video. The camera will reject U1 cards when trying to shoot video.

 

Sony A6100 Memory Card Recommendations

Memory Card For The Sony A6100The Sony A6100 uses a single UHS-I memory card slot with a top write speed of about 38.5MB/s.

Sony 4k video has a compression of 400Mbps, which translates to 12MB/s. Any UHS-I memory card will work for 4k video as long as it’s of the U3, or V30 speed class. Do not use U1 cards.

You can use UHS-II memory cards like the Sony E card. You won’t gain any speed in-camera, but you can get fast transfer speeds from your card to your computer if you use a UHS-II memory card reader. This is useful if you’re using your camera for a lot of video recording.

Memory Card Recommendations In-Camera Write USB Write USB Read Order
Sandisk Extreme Pro U3 38.51MB/s 88.3 99.2 Amazon
Sony E UHS-II* — 103.8 282.3 Amazon
Delkin Black U3 Tough 37.10MB 78.8 99.6 B&H
Delkin Advantage U3 37.10MB/s 78.8 99.6 Amazon
Kingston CanvasReact A1 U3 36.66MB/s 82.5 99.6 Amazon

 

*The Sony E card is a new UHS-II card optimized for UHS-I write speeds, but with UHS-II read speeds which is great for video shooters that need to transfer footage to their computer quickly.

Memory Card Speed Test | In-Camera Test Results

This is a list showing how each card performed in the Sony A6100.

To test the cards in the camera we run each one through a series of continuous bursts at the highest speed possible. The time for the buffer to clear is then calculated against how much data was written. We do this a few times for each card to look for any flaws then take the best results.

Although UHS-II cards are showing slightly faster results, you’ll still want to stick with UHS-I cards for the A6100. The A6100 does not have the second row of pins to utilize UHS-II cards and it’s a waste of money to buy them.

A6100 Bottlenecks

There is a little bit of a bottleneck happing with memory card write speeds in the A6100. It’s likely Sony is only using slightly older hardware like UDMA 4 for interfacing with the memory card. This will bottleneck the speed which is why most of the cards are running at about 38MB/s.

The good news is this makes choosing the fastest sd card a little easier since they all run close to the same speed.

 

Sony A6100 Video Record Times

Most of the Sony cameras are all shooting with the same video specs even the A6100.

You can shoot 4k at 30fps with 100Mbps, or 1080p up to 120fps.

Here a list of video record times for the different sizes of cards for the different record settings.

Resolution Format Bitrate 32GB 64GB 128GB 256GB
4k30p, 24p XAVC S 4K 100Mbps 43min 85min 171min 341min
4k30p, 24p XAVC S 4K 60Mbps 71min 142min 284min 569min
1080 120p, 100p XAVC S HD 100Mbps 43min 85min 171min 341min
1080 120p, 100p XAVC S HD 60Mbps 71min 142min 284min 569min
1080 24p, 25p, 30p, 50p, 60p XAVC S HD 50Mbps 85min 171min 341min 683min
1080 25p, 30p XAVC S HD 16Mbps 267min 533min 1067min 2133min
1080 60i AVCHD 24Mbps 178min 356min 711min 1422min
1080 60i AVCHD 17Mbps 251min 502min 1004min 2008min

 

Avoiding Counterfeit Cards

Since the Sony A6100 only has a single card slot, you will want to make sure that you get your memory cards from a trusted source to avoid anything counterfeit. 

When buying memory cards, avoid auction sites if possible and even be a little careful about buying cards on big sites like Amazon or Jet if you suspect they are sharing inventory with other stores. You can check this by seeing if there are multiple sellers of a card under a particular listing.

 

Checking Counterfeit Cards

Counterfeit cards usually work by hacking the memory controller to tell your camera the card has more flash than it really does.

This will allow your camera to run fine as long as you’re below that threshold. The second you try to write more data than there is flash, the card will completely die, wiping out all your data.

To check to see if you have a counterfeit card, just max out the capacity of the card when you first get it. You can do this by recording video to it or even drag and dropping footage to it from your computer.

 

Best SD Card Sony A6100 Conclusions

The Sony A6100 is a great update to the A6000 with new focus tech a new scree a new build and even a subtle improvement to memory card performance.

Stick with a good U3 UHS-I card and your camera should be good to go for a few years before you need to worry about memory cards again.
