Transcend RDF9 USB 3.1/3.0 Multi-Card Reader Review

May 10, 2017 By Eric Reagan

The Transcend RDF9 is a basic USB 3.1/3.0 memory card reader with slots for CF, SD and microSD cards. These are the memory cards I use on a daily basis – and I think that’s probably true for most photographers.  [Read more…]

Canon 5D Mark IV to Use CFast 2.0 Cards?

July 5, 2016 By Eric Reagan

5D Mark IV Rumor PB

New info from a “reliable source” at Canon Rumors points to the upcoming Canon 5D Mark IV and its change over to a CFast 2.0 card slot for its primary storage. The rumors note that it would feature both a CFast 2.0 card slot and a SDXC UHS-II card slot – both of which are a substantial upgrade from the 5D Mark III.

UHS-II Cards with Second Row of Pins

The 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. Of course, the UHS-II card slot will still be compatible with older UHS-I and non-UHS bus cards. You just won’t get the speed benefits that UHS-II cards offer.

CFast Card

Of course, CFast 2.0 offers even faster speeds with its SATA-3 connection at 6Gbps (up to 600MB/s) max data throughput. That is the fastest current mainstream memory card (XQD’s PCIe-based theoretical limit is 5Gbps).

Either of the card slots should be more than competent for whatever kind of compressed 4K video the Canon 5D Mark IV throws at them. The biggest question remaining to the bottleneck is Canon’s processing capability for still images. Is Canon simply going to build a 1D X Mark II Jr. as the 5D Mark IV?

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

March 1, 2014 By Eric Reagan

SanDisk_Extreme_PRO_SDXC_280MBs_NoClass_Front_64GB_HR

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…]

SanDisk’s New Extreme Pro SD UHS-II Cards are World’s Fastest SD Cards

February 12, 2014 By Eric Reagan

SanDisk_Extreme_PRO_SDXC_280MBs_NoClass_Front_64GB_HR

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…]
