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.
