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.

SanDisk Developing CFast2.0 Memory Cards, Not XQD Cards

SanDisk revealed at Photokina 2012 that it will be pushing toward memory card production on the new CFast2.0 specification memory cards and will not be delevoping XQD cards.

As of today, the only camera to support the XQD memory card format is the Nikon D4.  And while it is a great camera, no doubt, the single high-end model is not enough to push the demand in the market towards XQD as “the other memory card.”

CFast2.0 is a specification from the CompactFlash Association, which also designates the specification for current CF cards and the newer XQD cards.  CFast2.0 specs offer a theoretical performance up to 600MB/s data transfer speeds.

SanDisk is currently sampling new CFast2.0 cards to camera manufacturers to see if they will bite on the new specification in spite of the overwhelming move toward the SD card standard.  Medium format camera maker Phase One has already committed to putting the CFast2.0 cards to work in new cameras due to the higher performance over other card formats.
