Performance

As I mentioned before a Class 6 card has a write speed of up to 6MB/s when it is empty. A-DATA does include a lengthy 80MB marketing video and two PDFs on the memory card. These are just promotional items and can be deleted if you wish. To test the performance correctly, these files were deleted and the card was formatted once more using FAT32.

To bench the A-DATA Turbo Series card, a card reader was used which exclusively works with all MMC and SD formats. This provides the best performance and so the card reader will not become the bottleneck in the benchmarks.


HD Tach really surprised here, the card manages almost 20 MB/s read performance across the entire 16GBs.


As you can see, the A-DATA card bests all the other SD Cards we have taken a look at so far. Considering that even good card readers do not manage to tickle out 100% of the possible speed of the card the maximal performance possible should be just a wee bit higher, maybe one MB/s or so.


ATTO further surprised with very good write speeds. Even though the card is a Class 6 card, which only "offers" 6 MB/s the A-DATA Turbo Series manages to write at almost 10 MB/s. The read performance is on par with the results of HD Tach.
