REPORT ANALYSIS & FINAL THOUGHTS
For SanDisk to come so close to saturating the new industry standard of high-speed media before others even get off the ground is amazing. UHS-II takes the media professional in an entirely new direction. The SanDisk Extreme Pro SDHC UHS-II card has easily become the fastest SD card on the planet! The ONLY negative we had about this report was the fact that this SD card is even available in a 16GB size. Considering 3 of our staff each carry their own Canon EOS 6D full frame DSLR, we should be fighting over such a card, but the size becomes very restrictive at 16GB. Hopefully, we can get our hands on the 64GB capacity in the near future to confirm full performance as detailed.
The SanDisk SD card reader also proved to be one of kind during our testing of the SanDisk SD card. We tried to test the SanDisk SD card with the Kingston USB 3.0 card reader. To be completely honest, the SanDisk card reader can be a little difficult to use at first, especially if you are not aware of the dual set of contacts the SanDisk SD card features. You have to ensure that the SanDisk SD card is completely inside the card reader, otherwise you will see throughput lower than 50 MB/s, a mistake that can easily be made if unaware. When we double-check through put with the Kingston SD Card reader, we achieved similar results, less than 50 MB/s. Again, another little point that is necessary to achieve optimum performance from the SanDisk SD card.
In regards to the performance, a variety of steps were taken to try to achieve the listed 280 MB/s mark. C-States were disabled, and still we were not able to reach the 280 MB/s mark. Our thoughts are that the 16 MB/s SD card is not capable of the increased SD card speeds due to the capacity of the card itself. However, it is possible with larger capacity cards that we could see increased speeds to the point of the listed 280 MB/s mark.
Yet still, where else are you going to see speeds this fast? Let’s face it, going back a few years we were seeing SATA 2 solid state drives just a bit higher than these speeds, quite a significant difference, don’t you agree? To bring it into perspective further, think of the size of a SSD, and compare it to a SD card. Imagine achieving the same throughput from a storage device that is a mere 1/16th of a SSD, incredible! It is for this reasoning and rationale that we easily award the SanDisk SDHC card with The SSD Review’s Innovation Award!
