The Sony G Tough card is the flagship, top-performing UHS-II SD memory card. It has a V90 rating, which means a minimum write speed of 90MB/s or 720Mbps.
For 4k or 8k recording, this card will work with any camera that supports a video bitrate of 720 Mbps or less.
Sony has a history of making tougher-built cards, and these memory cards are 18 times stronger than traditional SD cards. However, to ensure maximum durability, they’ve removed the write-protection switch.

Sony G Tough Memory Card Benchmarks
Using the Prograde CFeB+UHS-II Reader and AJA System Test, the Sony Tough G v90 UHS-II cards achieved write speeds of 258 MB/s and read speeds of 296 MB/s, which are marginally slower than some of our other cards with USB-C speeds, such as the SanDisk Extreme Pro V90 card. However, it’s within the margin of error we get from using different readers, different card brands, and different testing software. For example, I can usually pull slightly faster results with CrystalDiskMark. However, I’ve switched to AJA for this site for consistency and can test various video codecs.
When testing the Sony G Tough cards with in-camera buffer tests, they’re usually among the top performers, alongside the SanDisk Extreme Pro. To see how this card performs in-camera or to compare it to other cards, see our SD memory card comparisons.
| Card Name | USB-C Write | USB-C Read |

When testing sustained Disk Write Captures, the card’s performance consistently bounces around 260MB/s. I did not see a performance drop after multiple 16GB tests to heat the card.
