Sony Professional U3 Review
The Sony Professional U3 SD card is available in 32GB, 64GB, and 128GB sizes.
With USB-C read speeds it clocked in a 98.5MB/s and with write speeds at 60.2MB/s.
To benchmark this card we used Crystal Disk in Windows 10 and a UHS-II USB-C Sandisk Memory card reader.
In terms of speed and performance, this card is just midrange compared to other cards in its class, and we haven’t seen any updates since 2016.

With a tough and durable design, the Sony Professional makes a great U3 UHS-I memory card for both photographers and videographers. With a 30MB/s guaranteed write speed, the cards are rated to work with any video resolution with a bitrate up to 240Mbps.
