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. [click to continue…]
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. [click to continue…]
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.
The SD Association has a new speed class standard designed for 4K video capture. The new cards will be labeled as UHS-I or UHS-II Speed Class 3 cards, which will define them as capable of a minimum 30MB/s constant write speed. [click to continue…]
Amazon has a solid deal on a Sony 64GB Class 10 SDXC card for $33.99 (reg. $64.99). Check it out here at Amazon.com.
Class 10 cards deliver on speed for HD video capture, which goes along with the size advantage of the SDXC spec. For more details on what all the classes and card specs mean, check out my resource article Demystifying SD Cards.
