The Sony NEX-6 ($648) has one memory card slot that supports both Secure Digital (SD) format and Memory Stick Pro Duo format memory cards. Given that SD cards are compatible with a wider range of cameras and the performance of the two types of cards is similar, we recommend using an SD card with the Sony NEX-6. Those who specialize in HD video and continuous shooting should consider the Sony Memory Stick Pro-HG Duo below.

Max. Write Speed: 45 MB/s
Max. Read Speed: 45 MB/s

The SanDisk Extreme is our pick for the best overall SD memory card for the Sony NEX-6. For $31 for a 32GB card, the SanDisk Extreme offers write speeds of up to 45 MB per second and performs far better than cheaper cards with respect to large files, video, and downloading. In addition, SanDisk Exteme 16-64GB cards are rated as waterproof, shockproof, X-ray proof, and can operate in temperatures from -13 to 185 degrees Fahrenheit.

If you frequently shoot HD video, high-speed bursts, or transfer large volumes of files, the best professional SD memory card for the Sony NEX-6 is the SanDisk Extreme Pro. With write speeds of up to 90 MB per second, it’s SanDisk's fastest SD memory card. Like the Extreme series above, the SanDisk Extreme Pro features a durable design that is waterproof, shockproof, X-ray proof, and rated for extreme temperatures. 

 

On a Budget

The Transcend Class 10 is a popular and economical SD memory card with a minimum write speed of 10 MB per second (more than double the SanDisk Standard Class 4 for only a few dollars more). However, the SanDisk Extreme above is relatively close in price, considerably faster than the Transcend, and more durable. 

 

Best Memory Stick Pro Duo Card

Min. Write Speed: 15 MB/s
Max. Write Speed: Unknown
Max. Read Speed: 50 MB/s

For those who frequently shoot HD video, the Sony Memory Stick Pro-HG Duo has a minimum write speed of 15 MB per second with the Sony NEX-6. The extra speed won’t be discernable to most people, but for video and continuous shooting the Sony Pro-HG Duo is the fastest memory card on the market for Sony NEX cameras. Another memory stick option, the SanDisk Ulta Memory Stick Pro Duo 32GB ($86), doesn't measure up with a minmium write speed of only 10 MB per second.
