This overlaps with the newer V10 class. Classes 2, 4, and 6. It is technically still possible to find older, slower cards that are Class 2, 4, or 6, but most modern cameras are likely to work better with at least Class 10 cards, especially for recording video. You might have seen an A1 and A2 ratings on some of the new cards and wondered what that is.
The A rating is a separate specification, not one in the same sequence. Up to this point, the primary market for memory cards has been for storing media like videos or photos.
But increasingly, devices can run apps directly from a memory card. V30 or V60 or U U1 or U3. You can also tell them apart by looking at the cards themselves. UHS-I cards have a single row of pins on the back. UHS-II have two rows. In this example, both of these are SanDisk Extreme Pro cards, just different generations. One is the design of the card. The speed of SD cards has come along in leaps and bounds in the past few years. Great write-up, very valuable info for a digital-photography noob like me.
Lexar x seems to be a device with solid performance for my small budget. Hi, thanks for putting all this information out there! I recently came across the following card, and wondered if it was on your list to test in the future? Thanks for the suggestion. That one is in my queue. Dear David: You have certainly provided us with a lot of Excellent information. However one item does not appear quite right. You list the Samsung EVO Sequential Write. Sequential Write Can You please explain why the big difference?
Thank You, den. Hi Den. I just went ahead and retested that card and am getting much the same results. Samsung does recycle their names, and there are older U1 EVO cards around. Kudos for the great research! Have you heard of it and might you be testing it? Should have results posted later this week. Thanks for the tip! Thanks for the tip on these. The V60 also performs very well. Thanks so much for following up on this.
I have the V90 on order for delivery this Wednesday. Would be awesome to see how it compares to the TOP Sony. Hi David! Can you throw your 2 cents in for me? Great article by the way! Great info. Both 32GB. Which is the better card? Im confused. What do you recommend according to the speed up to ? Thank you in advanced.

So it should be the same or so close to it as to not make any practical difference. But you mention Video Speed Class For cameras like the new GH5 that have ultra-high resolution video codecs, the faster cards like the Lexar x will be safer options. David, Are you able to advise what the specification is of these Class 60 cards ie. The tested speed of random writing to the card, which puts small chunks of data at different places of the card.
Would you have a similar comparison for microSD cards? I have searched extensively and all I have found so far is limited to 64GB density. Any help is greatly appreciated!

Hello David. First off all, thanks for your great Work. What do you think about it? Wich is the best of the list following these conditions?
You might want to correct that on your list. Thanks for all the info. Thanks for the tip. I bought a camera in January but would have held out if I knew about these cards. For example a MBs card would write at what speed in say a Nikon There is one for a low price I can get, if worth it. Then again I may not be able to afford a UHS-ll camera. Thank you. Thank you David for the helpful information. I think you mention in the article they give the same name to cards that have different spreeds. I looked up Sandisk Pro and found a few speeds. It;s moot. If I upgrade I will have a pretty fast card ready.
All the best. I bought this one for my Nikon D Is it a good one or i would have any problem? Super important but missing metric is the power consumption of various SD cards, since will significantly affect device battery life for extended recording like HD video, etc. It would be uber helpful if you can add into the comparison power consumption metric per GB stored for each of these cards.
