Blazing-fast Write Speeds of Lexar SD UHS ll Cards

Posted Jan. 2nd, 2016 by Daniel J. Cox

Blazing-fast write speeds of Lexar SD UHS ll cards was brought to my attention by Natural Exposure’s Explorer Gerry Heine. Gerry gave me the heads up to a great Blog post by the website calling themselves Camera Memory Speed. Their speciality is “Memory Card Comparison & Performance Tests for Digital Cameras.”

My first use of the speedy Lexar SD-UHS ll cards.

My first use of the speedy Lexar SD UHS ll cards took place on our first South Africa Invitational Photo Tour this past October. There were a few issues you can read more about in the Blog post titled:  New Lexar 1000 & 2000 SDHC-11 cards unreadable.

The tests were performed in an Olympus OM-D E-M5 ll camera, one of the few cameras that take advantage of the newest SD UHS-ll card speeds. I’m hopeful our Lumix cameras will soon have this capability as well, particularly in the form of an updated GH4. The GH5 maybe? Unfortunately, the Lumix GX8, which I’m currently working on a Blog post about, does not take advantage  of UHS-ll card speeds. Head over to the Camera Memory Speed blog to see the speed tests for yourself. It’s quite impressive for Lexar as well as Olympus. The only downside is the lack of service Lexar has shown in other situations. Awhile back one of our Explorer’s had issues with brand new Lear SDHC ll cards.

Update 6/5/2016

We never did receive ANY information from Lexar on this issue even after three different emails to their PR Department regarding the post New Lexar 1000 and 2000 SDHC ll cards unreadable. I emailed three different people which included Melissa Jenkins Latham, Andrew Rodger and a The email to was returned, the other two were not. Nobody ever did contact me about the issues we were having. Just astonishing that a company in this day and age would not respond to a Blog post that completely discredits their product. So that’s where it stands currently. Would still love to hear from them.

      Panasonic DMC-G7 manual, p. 15: “This unit is compatible with UHS-I/UHS-II* UHS Speed Class 3 standard SDHC/SDXC Memory Cards.” “*…UHS-II supports a theoretical transfer rate approximately three times faster than UHS-I.”

      I would expect newer cameras in the Panasonic Lumix G, GX, and GH range to support UHS-II, since a major feature on these cameras (at least on the G7) is 4k burst mode photography, including the very promising pre-burst 2 second mode which takes 30 frames before you press the shutter and 30 frames after you press the shutter, and allows 8k stills to be pulled from the 60 frames.

      Dan, I noticed the snow tubing series which looks like a 4k action series — Have you been satisfied with the quality of the 8k stills from the 4k mode? Have you tweaked the color settings at all? The G7 seems a little under saturated on the standard setting.

      Russ, I’m guessing our next Lumix camera will have support for the faster UHS-11 SD cards. Regarding the tubing series, yes that was pulled from a 4K Photo Mode/Video clip. The stills have been hard to believe. Just another great tool for getting action shots. As far as the G7 being under saturated I haven’t seen that to be an issue. But each to their own on colors and saturation. Thanks for writing in and let me know if you have any further questions.
