SanDisk has released a new 256GB Extreme Pro CF card with minimum sustained write speeds of 65MB/s and max write speeds up to 140MB/s. Read speeds max out at 160MB/s.
The cards are UDMA Mode 7 compliant for fast buffer clearance on supported cameras. SanDisk touts the new high-capacity card as optimized for 4K video capture, which is further highlighted by the VPG-65 specification (i.e., min. sustained write speed of 65MB/s). [Read more…]
. . . for some reason unbeknownst to me, Canon decided to build the 5D Mark III with one very fast CF slot which supports the newer UDMA7 protocol and a standard SD card slot which does NOT support the high speed standard (called UHS – for Ultra High Speed).
Jeff lays out the full details on his trials with the SD format over on his blog. Note that Jeff works for Lexar and knows more details about memory card specifications than the average photographer. Word from the horse’s mouth is also available on page 32 of the 5D3 manual with the express disclaimer that the camera does not support the UHS speed class standard.
I’m with Jeff on this one. It’s a real head scratcher why Canon wouldn’t support UHS-I in its cutting edge 5D Mark III. (The standard was announced way back in 2010 and has been pretty widely adopted thus far, including prosumer shooters like the Nikon D7000.) While it’s not as big a deal as a crippled AF system (ahem, 5D Mark II), this certainly is annoying and makes the SD slot unusable for some shooters out there.
Of course, Canon updated the 5D Mark II to provide support for the CF card spec UDMA-7 over 2.5 years after the camera was released. So, maybe we can hope a little bit that a similar firmware update would come to the 5D3 in order to put the SD card slot on nearly equal footing with the CF card slot. However, Jeff says that this could be a hardware limitation and not possible to update.
Has anyone else been plagued by the sluggish SD card problem on the 5D Mark III?

Lexar’s biggest CF card yet just dropped at CES 2012. The Lexar Pro 400x line of CF cards now includes a 256GB card, along with 128GB and 64GB available capacities.
The new cards are UDMA Mode 7 compliant and offer minimum transfer speeds of 40MB per second.
The 128GB and 64GB cards are priced at $469.99 and $299.99, respectively. No word yet on pricing for the 256GB CF card; however, Lexar says it will be available in the first half of 2012.

Kingston has joined the ranks of USRobotics and Lexar with its launch of a new USB 3.0 memory card reader that transfers data among CF, SD, microSD, and Memory Stick formats. The new card reader should be available soon at an initial retail price of $45.00. Check availability on Amazon.com.
For those unfamiliar with USB 3.0, it’s much faster than USB 2.0 and even FireWire. [Read more…]
USRobotics has a new USB 3.0 all-in-one card reader, which gives you faster transfer speeds for all of the popular memory card formats. [Read more…]
Canon has released a firmware update for the 5D Mark II. The new firmware version 2.0.9 provides the following updates.
- Improves writing/reading speeds when using UDMA 7-compatible CF cards.
- Fixes a phenomenon where the IS function will not work when custom function C.Fn III-2 is set to [5: IS start] and the lens attached does not have an AF stop button. This is because custom function C.Fn III-2 allows users to assign IS start to the AF stop button on the lens
- Corrects misspellings in the menu screens displayed in Arabic, Portuguese, Spanish, and Thai languages.
The PhotoFast G-Monster X Drive is a USB 3.0 enclosure for CF cards and 1.8″ hard drives. Essentially, the G-Monster X Drive turns a CF card or micro-sized hard drives into an ultra-compact, high speed hard drive.
Recently, I added a USB 3.0 PCIe adapter and an external USB 3.0 hard drive to my desktop PC as a media drive for video editing. So far, it has worked very well – with no discernable difference in performance from my internal hard drives. I have since become a big fan of USB 3.0 tech and was glad to hear about the G-Monster X Drive from Photofast. [Read more…]
Lexar announced a number of new additions to its product lineup at CES 2010.
Lexar added a 32GB capacity to its 300x Professional series of CF cards. Additionally, 16GB and 32GB capacities have been added to the 233x CF Pro series.
Lexar’s biggest buzzing product was a new Echo drive series, which are small USB drives that can be set to back up specific files or folders. During a product demo, I saw the utility of how these drives can help photographers working in the field. These drives can be used to automate the backup portion of your workflow, which helps speed things up when you’re out in the field.
As you can see from the above shot of the Echo ZE, Lexar has managed to fit 32GB into a tiny form factor. The Lexar Echo SE drive is bigger, more like a normal-sized USB stick; however, according to Lexar, it is much faster.
