Transcend SDXC/SDHC UHS-I U3 £27, $45
Featuring a quoted 95MB per second read speed and 85MB per second write speed, the Transcend appears to offer a good balance of both. In our tests it showed read speeds of 82MB per second and a write speed of 65MB per second, which was comparable with the other cards on test. In the buffer test, it achieved reasonable speeds of 27MB per second.
Transcend has tested this card for durability, and it features built-in error detection and correction and has been tested to work in temperatures from -25 through to 85 degrees Celsius. It also comes with RecoverRX photo software, which enables you to rescue files that you may have deleted by mistake. This software can be freely downloaded from the Transcend website with the purchase of the card.
The read and write times are decent enough, but we’d expect more from a UHS Class 3 card
