for burst shooting mode? If not, could someone recommend what's the minimum required?

"if I buy 8 gallons of gasoline, will that be enough to last me until Monday?"

The card you linked to is advertised as being capable of 80 MB/second.

We can't accurately tell you whether or not it is "fast enough for burst mode", because we don't know what camera you are shooting, what burst rate it has, or whether you are shooting RAW files or jPegs.

Nor can we tell you "what is the minimum required" unless you provide us with these details.

"They're", "their", and "there" are different words with completely different meanings - please use the correct one.
"Fare" and "fair" are different words with completely different meanings - please use the correct one. The proper expression is "moot point", NOT "mute point".

Yes, of course, how stupid of me. :oops: I'm shooting RAW only with Canon 5DIII, and I typically like to shoot 5 burst shots and no more. Thanks.

If I were in your shoes, I would call the good folks at B&H Customer Service at 212-444-6784.

They are knowledgable. . Just tell them what camera you have and that you shoot RAW and ask what card speed you'll need to keep up with burst mode. They'll look it up and be able to tell you within a minute or two.

They will also be able to tell you what cards they have that meet your requirements, and tell you what the best value is and/or what cards they have on special deal. . Their prices are usually s good or better than anyone else's.

The CS reps that answer the phones know what they're talking about and speak English as a first language. . And they can take your order right over the phone.

I think of these CS folks as a resource, and I like to use the resources that are available to me so that I don't have to figure it all out and look it all up myself.

No, it is not a good choice for fast burst shooting. See below for reason.

Sandisk Ultra support "maximum transfer" rate of 80MB/s. This is actually their sequential read speed. This card only do sequential write at a little more than 10MB/s, making it a very poor choice for clearing buffer. You should step up to Sandisk Extreme card, even the 45MB/s write card will a noticeably improvement. Beyong that, the return is diminishing.

For 5DIII, you won't need too fast of card. The interface is limited to 25MB/s. So a 45MB/s Sandisk Extreme will be more than good enough. Sandisk Ultra card won't saturate the interface.

Thank you, exactly what I needed to know. :-)

Cameras have a buffer where images are kept before being written to memory card. Read your camera manual to find out the capacity.

I was looking at these on BestBuy. It's more expensive there, but I have to use its $50 reward before Feb. and I don't have anything else to get from there except those cards. I think I'll get 2 32GB and be done with it.

For best burst shooting on a 5D3 you need to use a fast CF card not a SD card. The 5D3 will give 36 RAW shots per burst before the buffer fills and the buffer will clear in 2 seconds. Compare that with a fast SD card you can only shoot 15 shots before buffer fills and it will take 16 seconds before the buffer clears. (These numbers based on 1066x Lexar CF card and 633x Lexar SD card). This is because the 5D3 can make use of UMDA 7 CF cards but can't fully utilize the latest UHS1 SD cards.
