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 XC-HG Duo, PRO-HG Duo, and PRO Duo memory.

You'll find one memory card slot in the A6300. You'll have to make a decision between an SD or PRO Duo memory card.

PRO Duo memory cards are a proprietary memory format held by Sony. For that reason, SD memory cards are quite a bit cheaper and can provide greater performance than PRO Duo memory cards.

In a rush? My unbiased recommendation is to get this SD memory card to use in the A6300:

SanDisk Extreme Pro 128GB UHS-I SD Card

SanDisk Extreme Pro 128GB SD Card

  • Best value for the money.
  • Capacities from 32 GB to 2TB.
  • Transfer speeds up to 170 MB/s.
  • Class 10 & UHS-I
  • Temperature Proof, Water Proof, Shock Proof, and X-ray Proof.

Best SD Cards

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

You do not need to purchase a card made by SanDisk for your Sony ILCE-6300. Make sure the name is cool. That will ensure you get fast read/write rates, dust resistance, and other professional features.

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

The issues I have had with memory cards has been when I have used inexpensive brands. Not having a brand name increases the chance of data corruption or card errors.

If you are looking to spend less, don't buy a generic card. You will avoid problems by purchasing a name brand SD card with a reduced storage capacity.

Sony A6300 SD Card Compatibility

SDXC, SDHC, and SD cards are usable in the Sony A6300. Use a memory card to get the optimal overall performance out of the A6300.

The brand new SDUC memory cards are not supported by the A6300.

Currently, there are four specs of SD (Secure Digital) memory cards. Newer memory specifications add more tech that allows for greater storage space as well as greatly improve read/write speeds.

  • 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 memory card is based on the sequential write and read speeds. SD card file write speed is essential for video as well as continuous shooting.

A slow SD card can cause a drop in the number of continuous images the Sony A6300 can take. This is because the camera's buffer is not able to write data to the SD card quickly enough.

When shooting video, a slow SD card can cause recording to end. The video file might also end up being corrupted. If you are going to record video, it is critical the SD card you use meets the required minimum continuous write speed for video.

Card read speed is nice to have for transferring files to a computer or laptop. If you have cards that are full, an SD card with a fast read speed will reduce the transfer 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 A6300 requires no less than a Class 4 SD card.

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

Here are all of the Class ratings and associated lowest 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

Nearly every SD card worth ordering for the Sony A6300 will be a Class 10 SD card. In the short time since the launch of the camera, SD cards have gotten so much 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 is available in SDUC, SDXC, and SDHC cards. The UHS bus makes it possible for increased file transfer rates.

There are three separate specs. 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 card. If the memory card has UHS, a Roman numeral I, II, or III can be found on the memory card label.

  • 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 A6300 PRO Duo Card Compatibility

The Sony A6300 is able to use either a PRO-HG Duo or PRO Duo 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 pay more to get a hold of a Sony PRO Duo card than a similar SD card. I would not recommend purchasing a PRO Duo memory card to use in your A6300 as a result of the increase in expense.

Image Capacity

  • 128GB - 37,120 images
  • 256GB - 74,240 images
  • 512GB - 148,4800 images
