Sony A6100 Memory Card Compatibility

Two different types of memory cards can be used with the Sony A6100. Sony PRO Duo, PRO-HG Duo, and XC-HG Duo can be used in the camera as well as SD, SDHC, and SDXC memory cards.

There’s is only room for just one card to be in the slot at the same time. You will have to make a decision between a PRO Duo or SD card.

Sony owns the PRO Duo card format. SD cards have had a wider adoption that PRO Duo cards because SD cards are quite a bit faster and more affordable.

Need a card now? My advice is this SD card paired with A6100:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

Performance to price ratio is excellent. Fast enough to use in a camera upgrade.

Best SD Cards

SanDisk, Lexar, and PNY are brands that make the best Memory cards. The best SD cards I have used have been SanDisk Extreme Pro SD cards.

You do not need to buy a card made by SanDisk for your Sony ILCE-6100. Just make sure the name sounds cool. That will ensure you get fast read/write rates, dust resistance, and other professional features.

I have not had problems with PNY Elite Performance or Lexar Professional memory cards.

When I have encountered problems with memory cards has been when I have used cheap generic brands. A low-cost card increases the possibility of card failure or data corruption.

If you want to spend less, don't buy a generic card. You will be better off purchasing a high-quality card with a reduced storage capacity.

Sony A6100 SD Card Compatibility

SD, SDHC, and SDXC memory cards can be used with the Sony A6100. Use a card to get the maximum performance from the camera.

The brand new SDUC memory cards are not supported by the A6100.

Currently, there are four different types of Secure Digital (SD) cards. Newer memory specs add features that allow for more storage capacity and improved read/write rates.

  • Secure Digital (SD) - 128MB to 2GB.
  • Secure Digital High Capacity (SDHC) - 4GB to 32GB.
  • Secure Digital eXtended Capacity (SDXC) - 64GB to 2TB.
  • Secure Digital Ultra Capacity (SDUC) - 4TB to 128TB.

SD Card Speed

Speed ratings of an SD card is based on the sequential read and write speeds. The transfer speed of an SD memory card is very important for continuous shooting as well as video.

A slow SD card can decrease the number of continuous frames the Sony A6100 can take. This is because the camera's buffer is not able to write data to the card quickly enough.

With video, a slow card can cause an abrupt end to recording. The video file might also end up being corrupted. If you are going to capture video, it is crucial the SD card you use meets the required minimum continuous write speed for video.

Read speed is important for file transfers to a computer. If you are filling up cards with images or video, an SD card with a fast read speed will save you time.

Speed Class Rating

Example of where to find SD Card Speed Class
10 inside of a C showing that the SD card is Class 10.

The Sony A6100 requires no less than a Class 4 SD card.

A memory card is given a Class rating based on the sustained transfer rate of the memory card. Class 10 is the top rating, even though memory cards exist that have a higher read speed.

Here you can see a list of the Classes and their corresponding minimum read/write speeds:

  • Class 2 - 2MB/s
  • Class 4 - 4MB/s
  • Class 6 - 6MB/s
  • Class 8 - 8MB/s
  • Class 10 - 10MB/s or faster

Virtually any SD memory card worth ordering for the Sony A6100 will be a Class 10 card. In the short time since the announcement of the camera, SD memory cards have gotten a good deal faster.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
This card has a UHS-I rating. UHS-II and UHS-III cards will have II or III, respectively.

The Ultra High Speed (UHS) bus comes in SDHC, SDXC, and SDUC cards. UHS allows for faster file transfer rates.

There are 3 separate specifications. They are UHS-I, UHS-II, and UHS-III.

You can find out the UHS rating of an SD memory card by examining the front of the SD memory card. A Roman numeral I, II, or III on the front of the SD memory card, that is the rating of the SD card.

  • UHS-I - Maximum transfer rate of 104 MB/s
  • UHS-II - Maximum transfer rate of 312 MB/s
  • UHS-III - Maximum transfer rate of 624 MB/s

Sony A6100 PRO Duo Card Compatibility

The Sony A6100 is able to use a PRO Duo or PRO-HG Duo memory cards. What PRO-HG signifies is that the memory card has a minimum read speed of 50mb/s and a 15mb/s minimum write speed.

You'll need to hand over double the amount to get a hold of a Sony PRO Duo memory card than an equivalent SD card. Considering the price difference, I will not recommend purchasing a Sony PRO Duo card for use in an A6100.
