Best Sony SLT-A65 Memory Card

The Sony A65 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 memory.

You'll find one memory card slot in the A65. 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 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 A65:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

The best price to performance ratio. Transfer speeds are good enough to use in a camera upgrade.

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 SLT-A65. 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 A65 SD Card Compatibility

SDXC, SDHC, and SD cards can be used by the Sony A65. In order to get the most overall performance from the A65, use an SD card.

The most recent SDUC memory cards can't be used with the A65.

Currently, there are four specs of SD (Secure Digital) memory cards. Newer memory specifications add more tech that allows for increased storage space as well as improved 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. Memory card write speed is essential for continuous shooting as well as video.

A slow SD card can cause a drop in the number of continuous images the Sony A65 can take. This is due to the camera's buffer not being able to write data to the SD card quickly enough.

When shooting video, a slow SD card can cause an unexpected end to recording. The video file might also end up being corrupted. If you are going to record video, it is crucial 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 A65 requires no less than a Class 4 SD card.

An SD memory card gets 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 can be purchased that are quite faster.

Here are all of of the Classes 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 picking out for the Sony A65 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 built into 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.

To find out the UHS rating of an SD card, look on the front of the card. A Roman numeral I, II, or III on the front of the card, that will be the rating of the 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

Sony A65 PRO Duo Card Compatibility

One PRO-HG Duo or PRO Duo cards can be used in the Sony A65. What PRO-HG signifies is that the memory card has a minimum read speed of 50mb/s and a 15mb/s minimum write speed.

Sony Pro Duo memory cards are almost always twice as expensive as an SD memory card. Considering the price difference, I will not recommend purchasing a Sony PRO Duo memory card for use in an A65.
