SanDisk ‘4K-Ready’ Extreme Pro SD UHS-II Cards Now Available for Pre-Order


SanDisk’s new high-speed Extreme Pro UHS-II cards are now available for pre-order.

Recall that 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. The only camera so far to support UHS-II is the new Fuji X-T1.

The new SanDisk UHS-II cards offer write speeds up to 250MB/s and read speeds up to 280MB/s. The Speed Class 3 rating delivers a minimum sustained write speed of 30MB/s, which is relevant to video shooters since it allows capture of the compressed 4K video formats we are starting to see on cameras. Expect this to become a bigger theme this year. [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

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.
