The Sony G Tough card is the flagship top-performing UHS-II SD memory card. This card has a v90 rating which means a minimum write speed of 90MB/s or 720Mbps.
For 4k or 8k recording, any camera that offers a video bitrate of 720Mbps or less will be able to use this card without any problems.
Sony has a history of making tougher build cards, starting with their Professional UHS-I card several years ago, and now the Tough M and G UHS-II cards. These memory cards are 18 times stronger than traditional SD cards, but to ensure top durability, they’ve removed the write protection switch.
Sony Tough SD Card Review
The Sony Tough G cards gave us a write speed of 270.6 MB/s and a read speed of 229.1 MB/s which is a little slower than some of our other cards with USB-C speeds. However, this was tested with the Sandisk UHS-II USB-C memory card reader to keep all tests consistent with brands. And speeds do vary slightly depending on what brand of memory card reader is used.
Typically when tested in-cameras, this is one of the top-performing cards alongside the Sandisk Extreme Pro. To see how this card performs in-camera check out the memory card guide.
| Card Name | USB-C Read | USB-C Write |
| Sony Tough G | 270.6 MB/s | 229.1 MB/s |
Sony also makes some great UHS-II readers that I would recommend you pair with their cards since they are likely designed to be exactly compatible with the type of flash and memory controllers Sony is using.
