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.

Lexar’s New 256GB SDXC UHS-I Card is $900

Lexar announced a new 256GB SDXC UHS-I memory card at Photokina 2012.  While Lexar get’s the claim the world’s largest SD card for a short time, the new card will retail for $900 when it arrives in stores next month.

The new card offers a minimum guaranteed read speed of 60MB/s; however, Lexar is mum on the write speed, only saying that it is slower.  Of course, the Class 10 certification means that it will handle HD video from any camera that uses SD cards, which is most likely the only real purpose for using a card this big . . . for now.

In the mean time, you can pick up a 128GB card from Lexar’s same 400X Pro line for $120.
