Best Sony A230 Memory Card

The Sony A230 has two memory card slots, each using a different card format. One card slot is able to use SD and SDHC cards. The second memory card slot uses Sony PRO Duo and PRO-HG Duo memory cards.

SDHC cards can be used, consequently, the largest SD memory card that you can use is 32GB. The PRO Duo and PRO-HG Duo slot uses 16GB and smaller memory cards.

One card slot can be used at a time. A switch inside the card door is where you decide on which memory card slot to save images.

PRO Duo memory cards are a proprietary memory card format that is owned by Sony. Due to that, SD memory cards are lower priced and frequently provide better performance than PRO Duo cards.

In a rush? My recommendation is to get this SD card with the Sony Alpha A230:

SanDisk Extreme Pro UHS-I SDHC Memory Card

SanDisk Extreme Pro 32GB SDHC Memory Card

64GB or larger cards are not compatible with the camera.

Best SD Cards

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

That does not mean you need to buy a card from SanDisk for your Sony A230. Make sure the name sounds impressive. That will make sure you get fast transfer rates, shock resistance, and more features.

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

The problems I have experienced with cards has been when inexpensive generic brands were used. Being cheap increases the possibility of corrupted data or card errors.

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

Sony A230 SD Card Compatibility

SDHC and SD memory cards are compatible with the Sony A230. If you'd like the optimal performance, use an SD card.

The most recent SDUC and SDXC memory cards are not compatible with the A230.

Currently, there are four different specs of SD (Secure Digital) cards. New card specifications add more tech that provides for more storage space as well as much faster transfer 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

The speed rating of an SD card is dependant on the sequential write and read speeds. The write speed of a card is important for clearing the buffer for continuous shooting and recording video.

Slows memory cards can cause a reduction in the number of continuous frames the Sony A230 can capture. This is because the camera's buffer is not able to write to the card fast enough.

With video, a slow SD card can cause a sudden end to shooting. The video file could also be corrupted. If you are going to shoot video, it is crucial the card you use meets the minimum requirements of the camera.

Card read speed is nice to have for file transfers to a computer. If you have cards that are full, an SD card with a fast read speed will reduce the amount of time it takes the transfer to finish.

Speed Class Rating

10 inside of a C showing that the SD card is Class 10.

An SD card gets a Class rating based on the sustained continuous write speed of the card. Class 10 is the top rating, even though memory cards are available that have an improved read speed.

Class Speeds

Here is a list of the Classes and their associated 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

Nearly every SD memory card worth owning for the Sony A230 will be a Class 10 memory card. In the time since the release of the camera, Memory 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 SDHC, SDXC, and SDUC cards. UHS makes it possible for faster file transfer rates.

Three separate versions exist. They are UHS-I, UHS-II, and UHS-III.

To find out the UHS rating of a memory card, look on the front of the card. If the card has UHS, a Roman numeral I, II, or III can be found on the label.

UHS Transfer Rates

  1. UHS-I - Maximum transfer rate of 104 MB/s
  2. UHS-II - Maximum transfer rate of 312 MB/s
  3. UHS-III - Maximum transfer rate of 624 MB/s

Sony A230 PRO Duo Card Compatibility

One of the card slots will accept PRO Duo and PRO-HG Duo memory cards. PRO-HG signifies the card may have read transfer rates up to 50MB/s and a 15MB/s minimum write speed.

Only PRO Duo cards with a total of 16GB or smaller will be usable in the A230.

PRO Duo cards are around twice as expensive as an SD card. As a result of the added cost, I do not recommend purchasing a PRO Duo card for the A230.

Do Both Memory Cards Slots Need to Be Used in the A230?

No, the Sony A230 is unable to use the two card slots at the same time.

Competing camera companies have cameras that can use both memory card slots at the same time. That gives added features such as mirroring the cards, overflow protection, as well as splitting up JPEGs and RAW files.

Not having the features to use dual card slots for expanded features, means you shouldn't waste the additional money on a PRO Duo card.

Below is an approximate estimation of how many large JPEG images you can expect to store on each size of SD card. You can find more detailed info about file sizes based on settings in the camera manual.

  • 8GB - 2,320 images
  • 16GB - 4,640 images
  • 32GB - 9,280 images
