Buying Guide: What to Look for in an SD Card for Your Sony Camera
Speed Class and Video Performance
For Sony cameras that shoot 4K video, you need a card with at least UHS Speed Class U3 and Video Speed Class V30. These ratings ensure sustained write speeds of 30 MB/s or higher, preventing dropped frames during long recordings. Cards like the SanDisk Extreme PRO series are certified for these standards and handle 4K UHD without breaking a sweat. For more on 4K video storage, see our best micro SD cards for 4K video article.
Read and Write Speeds
Fast read speeds (200 MB/s and above) speed up file transfers from the card to your computer, while high write speeds (90 MB/s or more) let you shoot rapid burst sequences without a lag. The SanDisk Extreme PRO cards boast read speeds up to 250 MB/s, making them ideal for high-resolution stills and rapid workflows. If you often shoot in burst mode, prioritize cards with write speeds above 90 MB/s.
Capacity and Durability
Capacity matters: 64GB is a good starting point for casual shooting, while 128GB or more is better for extended video projects. All the cards we reviewed are built to withstand extreme temperatures, shocks, and X-rays, essential when you’re shooting outdoors.
