SanDisk has released new UHS-II SD cards with write speeds up to 250MB/s and read speeds up to 280MB/s. This new line gets its major speed boost from the UHS-II bus interface. Most SD-compatible cameras currently on the market support UHS-I, at best; however, we are just starting to see new cameras with UHS-II support (like the Fuji X-T1).

The new UHS-II bus interface offers the ability to build cards with up to 312MB/s transfer speeds, which is a big jump from the maximum theoretical speeds on the UHS-I interface at 104MB/s. [Read more…]

 

Kingston Unveils SDHC/SDXC UHS-I Speed Class 3 Cards for 4K Video Capture

Kingston SDXC UHS-I U3 64GB Memory Card

To go along with the new Panasonic GH4 4K camera that will be announced later tonight / early tomorrow, Kingston is first out of the gate with its official announcement of a new SDHC/SDXC UHS-I Speed Class 3 card in 16GB, 32GB and 64GB capacities. The new Speed Class 3 card guarantees minimun write speeds of 30MB/s.

The minimum write speed of these cards translates to roughly 240Mbps, which fits well within the max on-board data rate of the Panasonic GH4’s 4K capture at 100Mbps for its IPB .mov/.mp4 4K capture and 200Mbps for its ALL-Intra .mov and .mp4 HD capture. Additionally, the new Kingston card provides max speeds of 90MB/s read and 80MB/s write.

Pricing isn’t all that bad either, considering the performance they offer. The 16GB cards run around $40 street and the 64GB cards are around $105 street. Check them out here on Amazon.com.

Eye-Fi 16GB Pro X2

Eye-Fi has unveiled a new 16GB Pro X2 SD card, which also sports a Class 10 designation. As you may know, Eye-Fi cards allow you to wirelessly transmit your images from your camera to your computer, tablet or smartphone over a WiFi network.  The Pro X2 cards also allow transfer of RAW files and can be configured to free up space after photos have transferred off the card.

The new 16GB Pro X2 cards run $99.99 and are available here at Amazon.  Additionally, Eye-Fi dropped the price on 8GB Pro X2 cards to $79.99 to make room for the 16GB models at the top of the food chain.

Don’t Buy Anything Less Than a Class 10 SD Card

No More Slow Memory Cards

I’ve seen a lot of deals lately on Class 4 and Class 6 SD cards mixed in with deals on Class 10 SD cards.  The price difference between these classes of SD cards is now nominal and, as a result, there’s really  no reason you should buy a Class 4 SD card anymore.

The prevalence of this problem came to light recently when a friend brought his Canon 60D to me, stating that it wouldn’t record video for more than a couple of seconds.  My gut told me to check the SD card first thing.  And, sure enough, he had an old SanDisk Ultra Class 4 SDHC card in it.  I swapped it out with one of my SanDisk Class 10 SDHC cards and it worked like a charm.

He ordered a new Class 10 SDHC card that day.  His 60D has captured video just fine ever since.

If you don’t already know, the Class-ratings on SD cards relate to a minimum write speed. When recording HD video, you need a minimum-sustained write speed in order to dump the data off the camera and onto the card.  In many cameras today, Class 4 (4MB/s) and Class 6 (6MB/s) cards just can’t handle the data transfers.

Class 10 cards are currently the fastest rated for minimum write speeds available and will handle video capture for most, if not all, current HD video DSLRs and camcorders today.

If you want to know more about SD card speed ratings and classifications, check out my article on Demystifying SD Cards.

If you want an easy recommendation, go with SanDisk Extreme Class 10 SD cards.

SanDisk Extreme Pro UHS-I SD Card in the Nikon D7000

By

The Nikon D7000 is the first DSLR to take advantage of the new UHS-I SD card specification.  Unfortunately though, it doesn’t appear to take full advantage of that speed potential.  The Nikon D7000’s buffer seems to cap at 10 frames during continuous high speed shooting no matter which SD card is inserted.

I got my hands on the latest SanDisk Extreme Pro UHS-I SDHC cards, which are due out in March, to see just how well they worked in this first-generation UHS-I camera.

While the difference between the SanDisk Extreme and Extreme Pro SD cards is marginal in the D7000, there is still an obvious difference.  After capturing the full complement of 10 frames at the D7000’s max frame rate of 6fps, the D7000 delivered the following results with each of the cards.

This article was sparked by a recent conversation I had with some folks at SanDisk.  We were talking about the numerous types and ratings of SD cards and how there are lots of questions from users about the acronyms, labels and speed ratings associated with SD cards.

In this article, we’re going to look at the different types of SD cards, along their speed class designation, and why these are important for you and your camera.  By the end of this article, you should have a better understanding of what works in your camera and why.  Moreover, you should be able to choose the right SD card for your camera and the way you want to use it.
