Speed is only one factor, so your comment was rather overly simplistic and based on unstated assumptions.

If the OP knew anything about the differences between cards he would know why what he was told was problematic. Providing overly simplified answers doesn't always help.

So no pair of slacks, maybe an old sock at best! :D :D

Probably not for b&w or macro, but quite possibly for video, sports or birds in flight in comparison to landscapes and so on.

If I shoot a single frame of a bird in flight, or a single frame of a sporting event or landscape the card makes 0 difference. In taking multiple shots speed could make a difference. That is what Longshadow said.

Instead of keeping things photographic, and trying to help, you always try to complicate things. I'll bet there are engineering sites where the extra information could be helpful, but they don't help anyone get a better picture.

But, as long as you are having fun, that's cool.

Neither does providing overly complicated ones. (or zeros).

Sometimes correcting incorrect and misleading information is appropriate. Your statement that "A card is a card, except for the speed differences" is fundamentally wrong whichever way you cut it.

If you consider how many questions we get from people having problems with memory cards that relate to things other than speed you might consider that pointing out that it can be complicated in various ways may have some value.

Well, if you look at the recurring threads we have about people having issues with memory cards and other storage media which can and does affect their photography and the quality of their pictures perhaps you might see things from a different perspective.

You keep your opinion, and I'll keep mine.

I simply replied to the original question. If a different question comes up, I will reply in context to that question. I didn't think the OP needed information regarding how the information is stored in a charge state in the memory. Yes, while the different card types may have different physics in their operation, a card stores data, whether CF, SD, etc.
And yes, I'm having fun. :thumbup:

I appreciate all the input and will never have to wonder about this topic again. I only need to examine my SD card and make sure it is up to snuff. (I threw the wrapper away.)

Ok -- here is the label

A girl in a old sock, now there's a fetish worth looking in to.

It looks like it might be a class 10 (60 megabits per second).
Here's a speed chart:

Possibly, but you can't post the pictures on UHH! Sounds like a David Hamilton kind of thing....

Yes, based on the symbol of a 10 inside a 7/8 circle, it is a class 10. Based on your chart, it looks like my card is compliant. The camera manual states that it supports UHS-1 which I understand to be a step up from what I have. Also from your chart, I gather that the "writing performance" gains importance with video recordings. As I already have a quality Handy-cam, I am unsure as to how much video I will be shooting with this camera. I'll be able to answer that when I get to that part of the learning.

IMHO - The CLASS specification is a waste of time... it ONLY defines a MINIMUM speed rating... as in Class 10 is at least a 10 MB/s card... buy if your camera supports UHS-1 then it tops out at roughly 104 mB/s, so it would pay to get a card that can read /write well above the 10 MB/s speed.

For example, I use a pair of Samsung Pro 32 GB cards in my D7100 - they provide a good burst speed, writing at about 80 MB/s, and they were purchased fairly cheaply.
