Performance

The performance of the Delkin Power UHS-II card was evaluated using a variety of card readers. In benchmark tests the Power 128GB card measured up to 296.9 MB/s sequential read speed which is very close to the 300 MB/s claim. The maximum sequential write speed was 235.3 MB/s, slightly below the 250MB/s maximum write speed claimed for the card.

When the card is used in UHS-I devices it reverts to UHS-I speed. This is shown in the UHS-I SD card reader benchmarks, where the card reached up to 96.6 MB/s sequential read speed in UHS-I mode. The maximum write speed in UHS-I mode was 87.9 MB/s.
