Interface Performance, Throughput

The interface benchmark reveals the maximum throughput of each of the cards. Note that this is usually limited by the card reader devices, as we didn’t find one capable of delivering more than 19.7 MB/s transfer rate for the cards via USB 2.0. We even tried an IDE card reader by Addonics, but it wasn’t faster than our Transcend M5.

Read transfer performance is limited by the card reader’s performance (which is a general issue), but write performance is much more interesting.

The most significant performance differences can be found in the write throughput benchmark, as the results vary between 9 MB/s and 18.6 MB/s.
