SD card differrence

I would not dare to buy a $5, 64 Mb. SD card. Like everything in life you get you pay for.
Fast cards with a reputation are more expensive.

SD cards are one of the most counterfeit items on the internet. People buy reject cards and rebrand. It's big business.

I have had only two failures EVER using "off brand" cards. Both were recent failures and both cards were <2 years old. Also, these are the ONLY two "off brand" cards I have EVER purchased. I also have many name brand (Sony, SanDisk, Lexar, etc.) cards that go back to when I first started in digital photography. Most are now way too slow to keep up with any of my three current Canon camera bodies, however, they are still being used in digital picture frames and to send pics back and forth to friends and family. God bless the United States Post Office (USPO) even with their high-speed mechanized mail handling machines have not destroyed them yet. LOL. Please don't get me wrong, I love the USPS since we have spent MONTHS trying to get the UPS drivers to quit placing our packages in front of or propping our packages up against my garage doors!!! What could possibly go wrong since we park both our vehicles in the garage? Haha! Sorry for the rant, but at least I submitted "more data". JimmyT

I believe that the higher speed SD cards are necessary for recording movies on the card.

Agreed! Sandisk "Extreme Pro" 32GB are all I use. Have quite a few of them.
95MB/sec read time is necessary when you shoot in burst mode.

SanDisk, Lexar, PNY, Delkin, and Sony are your best reliable name brands. Stick with them. And don't be dependent on using one high capacity memory card (64gb) on a multiple of cameras. Buy a spare memory card. The good ones are cheap now. I use 16gb to 32gb SD cards that are SanDisk and Lexar brands. No problems yet. All memory cards are not created equal.

Bud, It has to do first with reliability. I worked in the Semiconductor business which is what is in the SD cards. The cheaper cards have a higher mean time to failure. I would not want to risk important images to a card like that. Second, is speed. How fast your camera can read that information. So bottom line yes their is a difference.
Higher ????? I think you mean LOWER MTTF, eh ?

I agree with TriX, you don't want to get cheap on a card when you have spent all kinds of time and money on the rest of the variables. I use large cards, as I have two slots, an SD and a CF, and I replace the SD cards every two to three years. SD cards have exposed terminals, as oppose the internal terminals of a compact flash.

Sometimes the exposed terminals of SD cards cause issues, so it makes sense to replace them every now and again. However, a little cleaning of the terminals sometimes helps, if the card won't read on a computer. I have used even crude techniques like a shirt tail or a pencil eraser to do the cleaning and they have worked.

I recently went on a 10-day trip, and took all the cards I had. When I returned, I noted that the transfer speed from card to hard drive was far faster for the latest, fasted-rated cards. And, as others have said, the number of photos you can take in a burst, and the time required to clear the camera's buffer, are better for the faster cards.

The numbers on the card such as 95MB/sec are read times which has no bearing on how well the card will work for video or burst mode. The camera is "writing" to the card, not "reading" from it. Here is a chart that explains the different types of cards. The important thing is that the card is UHS speed class 3 which is the U with a 3 inside. This assures a minimum write speed of 30MB/sec which is required for 4k video.

SPEED COSTS MORE.
If you’re a video buff, the faster you can write to a card, the higher the quality you can record.
Always buy cards capable of A) working in YOUR camera and B) writing as quickly as needed for what you are recording. In both cases, see your owner’s manual. Card capacity and speed requirements vary considerably from camera to camera.

Thanks for the graphic. Its interesting. I guess I have not been keeping up, as I have been using the UHS speed class, and did not know about the Video speed class.
I took a look at the SanDisk offerings, but they do not seem to label V60 etc, but still have write speeds of the order of 260 MB/second with their SDHC2 cards.
