Best Memory Cards for Sony a6600

Looking for the best SD memory cards for Sony a6600? Here are our top recommended & fastest SD cards for Sony a6600 mirrorless camera.

The Sony a6600 mirrorless camera has a single SD card slot that supports UHS-I SD cards. That means there are no benefits to get a UHS-II card, unless you really need fast read speeds (which enables you to transfer files to your computer quicker). Featuring a revised 24.2MP APS-C Exmor CMOS Sensor, the latest BIONZ X image processor, and a front-end LSI implemented in Sony’s full-frame cameras, the Sony a6600 (Amazon, B&H, Adorama) is capable of up to 11fps continuous shooting with Real-time Eye AF and up to UHD 4K30p and Full HD 120p with no recording time limit. Simply put, with an emphasis on speed and versatility, the Sony a6600 is a sleek-yet-fully-featured APS-C-format mirrorless camera well-suited for both stills and video.

As we mentioned above, the Sony a6600 has only one card slot that is limited to UHS-I speeds. So for the Sony a6600 users, we highly recommend getting a fast and reliable UHS-I SD card like the SanDisk Extreme PRO UHS-I SDXC Card 170 MB/s (V30, U3). But if you have some other cameras that support the UHS-II cards, buying an UHS-II card would maximize your advantages and could be a better choice.

Below are our top recommended & fastest SD cards for Sony a6600 camera based on the speed and price. Just choose the one you like!
