Best SD Cards

In the time since the release of Panasonic GX9, the price of cards has come way down.

Seeing as how inexpensive the price range are, it does not be wise to pay for anything besides a professional-level card.

The best memory cards I use have been the SanDisk Extreme Pro, Lexar Professional, and PNY Elite Performance models. I have under no circumstances endured corrupted data or a card physically fail with any of those memory cards.

All of the trouble I have had has been with cheap unbranded cards. Seeking to save a little bit of money isn't worthwhile if your GX9 is likely to experience issues.

If you want to save some money, opt for a lower storage capacity memory card from a quality manufacturer. Because of this, you will not have to be worried about the photos stored on the SD memory card.

Speed, Class, & UHS Ratings

Card Speed

Speed ratings of an SD memory card is determined by the sequential read and write speeds. The continuous transfer speed of an SD memory card is essential for continuous shooting and video.

A slow card can cause a decrease in the number of continuous images the Panasonic GX9 can take. This is due to the camera's buffer not being able to write to the memory card fast enough.

When recording video, a slow card can cause an unexpected end to recording. The video file may also be corrupted. If you are going to capture video, it is crucial the card you use meets the minimum requirements of the GX9.

Card read speed is important for transferring files to a computer or laptop. If you are filling up cards with images or video, a card with a fast read speed will cut down on the time it takes the transfer to finish.

Speed Class Rating

Example of where to find SD Card Speed Class
The 10 inside of the C means the card is Class 10.

The Class rating of an SD card is determined by the continuous write speed. SD cards that have a write speed of 10MB/s will be labeled 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 name-brand SD card that you can buy online will be Class 10. To locate the class rating of a card, try to find a number inside of a C on the front.

Ultra High Speed (UHS)

Example of an SD memory card with a UHS-I rating.
The UHS rating of a card can be determined by a Roman numeral I, II, or III on the label of the card.

The Ultra High Speed (UHS) bus comes in SDHC, SDXC, and SDUC memory cards. The UHS bus memory cards to have increased read and write speeds.

Three separate specifications have been specified. The versions are UHS-I, UHS-II, and UHS-III.

You can determine the rating of a card by reading the front of the SD card. If there is a Roman numeral I, II, or III on the front of the card, that is the UHS rating of your 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
