Sony A6300 Memory Card Compatibility

The Sony A6300 is able to use 2 types of memory cards. SDXC, SDHC, and SD memory cards are compatible and in addition Sony PRO-HG Duo and PRO Duo cards.

The camera only has only one card slot. You will have to choose between an SD or PRO Duo card.

Sony is the owner of the PRO Duo format. Consequently, SD memory cards are less expensive and frequently have better performance than PRO Duo memory cards.

SanDisk, Lexar, and PNY are manufacturers that make high-quality SD cards. The best SD cards I have owned have been the SanDisk Extreme Pro memory cards.

That does not mean you need to purchase a card from SanDisk for your Sony ILCE-A6300. Just make sure the name is impressive. That will mean you get fast read/write rates, water resistance, and more features.

I have not had issues with Lexar Professional or PNY Elite Performance SD cards.

When I have encountered problems with SD cards has been when I have used inexpensive no name brands. Being cheap increases the chance of card failure or corrupted data.

If you are looking to save money, don’t buy a cheap card. You will avoid problems by buying a name brand SD card with a smaller storage capacity.

SDXC, SDHC, and SD cards can be used by the Sony A6300. If you want to get the optimal performance, use a SD card.

The brand new SDUC cards won’t work with the A6300.

Currently, there are four different specifications of SD (Secure Digital) cards. Newer card specifications increase tech that allows for larger storage capacity as well as much faster data transfer 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.

Speed ratings of an SD memory card is dependant on the sequential read and write speeds. SD card continuous write speed is essential for continuous shooting and video.

A slow SD card can cause a decrease in the number of continuous photos the Sony A6300 can take. This is because the buffer in the camera is not able to write to the memory card fast enough.

With video, a slow SD card can cause an abrupt end to shooting. The video file may also be corrupted. If you are going to record video, it is important the SD card you use meets the minimum requirements of the camera.

Read speed is important for transferring files to a computer. If you have cards that are full, a memory card with a fast read speed will save you time.

SD Card Speed Class
SD Card Speed Class

A SD memory card is given a Class rating based on the continuous write speed of the memory card. Class 10 is the best rating, even though SD cards are manufactured that are noticeably faster.

Here is a list of the Classes and applicable 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

Any SD card worth deciding to buy for the Sony A6300 will be a Class 10 card. In the short time since the camera was introduced, SD memory cards have gotten so much faster.

UHS-I Rating
UHS Rating

The Ultra High Speed (UHS) bus can be found in SDUC, SDXC, and SDHC cards. The UHS bus memory cards to have faster transfer rates.

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

To find out the rating of a SD card, look at the label. The presence of aRoman numeral I, II, or III on the front of the SD card, that is the UHS rating of your memory 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

The Sony A6300 may use one PRO-HG Duo or PRO Duo memory cards. PRO-HG signifies the memory card may have read speeds up to 50MB/s and a 15MB/s minimum write speed.

You’ll need to hand over twice as much to get a PRO Duo memory card than an equivalent SD card. I would not recommend purchasing a PRO Duo memory card to use in a A6300 on account of the increase in cost.

  • 128GB - 37,120 images
