Memory cards are now substantially less expensive than at the time the camera was newly introduced.

Since costs are low, it will not be smart to spend money on anything other than a professional-level SD card.

SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance cards have great performance and reliability. I have never endured data errors or a card physically fail with any of those SD cards.

All of the hassles I have experienced has been when using low-cost unbranded SD cards. Seeking to save a buck is not worth the cost if your A37 will not operate in the right way.

To save money, buy a lower capacity memory card from a quality manufacturer. Because of this, you will know your images are safe on the memory card.

Here is a quick approximation of just how many maximum-quality JPEGs pictures you should expect to be saved on a memory card:

  • 16GB - 4,640 images
  • 32GB - 9,280 images
  • 64GB - 18,560 images
  • 128GB - 37,120 images

Speed ratings of an SD card is dependant on the sequential read and write speeds of the card. SD card file write speed is critical for video as well as continuous shooting.

A slow card can cause a decrease in the number of continuous frames the Sony A37 can take. This is because the camera’s buffer is not able to write to the card quickly enough.

With video, a slow SD card can cause recording to end. The video file could also be corrupted. If you are going to record video, it is critical the memory card you use meets the requirements of the A37.

Read speed is nice to have for transferring files to a computer. If you have cards that are full, a memory card with a fast transfer speed will reduce the amount of time it takes the transfer to finish.

SD Card Speed Class
SD Card Speed Class

An SD card receives a Class rating determined by its sustained write speed. Cards that have a write speed of 10MB/s are labeled as Class 10.

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

Every brand-name SD memory card that you can purchase today will have a Class 10 rating. You can discover the class rating of a SD card by looking for a number inside of the C on the front.

The Ultra High Speed (UHS) bus can be gotten with SDUC, SDXC, and SDHC cards. The UHS bus memory cards to achieve increased write speeds.

Three different versions have been created. The versions are UHS-I, UHS-II, and UHS-III.

To find 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 seen on the front of the 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

Taking the facts into consideration, the 64GB SanDisk Extreme Pro is the best memory card for the Sony A37. Any future camera you buy, you will know what SD card to use.
