Best Value Sony A6600 Memory Cards

The Sony A6600 uses SD memory cards. It can use cards with a maximum capacity of 2TB.

A UHS-I SD card with a U3 or V30 rating is needed to record 4k30 video.

A 128GB capacity card will be enough for photography. Larger capacity cards will be better for video.

Do not spend money on a UHS-II card. The A6600 does not have a compatible slot. It will not be faster.

Sony A6600 SD Card Compatibility

The Sony A6600 is compatible with the SD, SDHC, and SDXC standards.

Check to make sure the camera has the latest firmware.

The newest SDUC (Secure Digital Ultra Capacity) cards will not work with the A6600. They are too large.

• SD (Secure Digital) - 128MB to 2GB.
• SDHC (Secure Digital High Capacity) - 4GB to 32GB.
• SDXC (Secure Digital eXtended Capacity) - 64GB to 2TB.
• SDUC (Secure Digital Ultra Capacity) - 4TB to 128TB.

Image Capacity

Here’s the approximate image capacity for high-quality JPEGs from the 24.3 megapixel sensor:

• 32GB - 4,240
• 64GB - 8,480
• 128GB - 16,960
• 256GB - 33,920
• 256GB - 67,840

Card Speed Class

Class rating is determined by sustained write speed. The rating will be shown as a number inside of a C on the label.

For example, as card that could write data at 5MB/s would get a Class 4 rating.

Class 10 card are likely much faster than 10MB/s. That’s why there are additional ratings for high resolution video.

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

Recommended SD Cards

Look for U3 and V30 ratings. Those cards will be fast enough to record 4k30 video.

A faster card, like a V60, will let you download files off a card faster. I don’t think that’s worth the added cost.

There will not be a difference in performance with the A6600.

Branding isn’t worth paying more for.

All U3, V30 cards are going to effectively be the same.

If you’re going to spend money on something, it should be a larger capacity.

For photos, 128GB should be good.

For video, more is better. That includes having multiple cards.

Don’t buy a UHS-II card. The A6600 doesn’t have the second row of contacts for UHS-II cards.
