SanDisk Extreme Pro UHS-II Memory Card Review – Fastest SD Card on The Planet!

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.

 

SANDISK SD CARD BACK

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.

SANDISK SD CARD FEATURED

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!

Fastest SD Card in the World

The SanDisk Extreme PRO SDHC UHS-II memory card is shockproof, x-ray proof, waterproof, has a lifetime warranty and reaches transfer speeds of 280MB/s. Need we say more?

It seems the bottleneck for most current DSLRs, including the 6D, is the controller card. So if you were to test the write speeds of the cards in the cameras, you’ll find that 50MBs will be the write speed limits so any card with a minimum write speed higher than that is superfluous on the currents cameras. The in-camera benefits of UHS-2 cards will not come until at least the next generation of semi-pro Canon or Nikon DSLRs. So far only the Fuji X-T1 will take advantage of UHS-II.

Very good point.

And the Samsung NX1 of course….. will be UHS II compatible

Wow, thats a wicked fast card. Too bad, pretty nothing supports UHS-II at the moment ;(

Writes and smaller reads are still limited by low IOPS. Sure a benchmark can get >180MBps with large sequential blocks but the smaller+random IOPS rates mean it is FAR FROM being SATA SSD performance.

Is there a currently selling camera that has these additional contacts (UHS-II), to take full advantage of this card?

Not yet… You may see it in a year or so… It is hard to tell in the camera industry where we see very little product change in comparison to other industries.

Could the bottleneck be the operating system? Windows 7 does not support USB Attached SCSI. This command set can significantly speed up flash storage access over USB by allowing commands to be queued, allowing the controller to execute them back to back instead of waiting for another command to be sent when the previous command is finished, and also allows the controller to execute commands out of order if that can be done safely and can speed things up. Windows 8 and later support USB Attached SCSI.
