If shooting in RAW burst mode, what is the minimum card speed I should consider? Thanks in advance.

What camera are you using? I just ordered lexar 1066 cards. They should be faster than the camera.

If your camera produces 20MB RAW files, and shoots 5fps, you need a card which will write as least 100MB/s. But many cameras cannot even write that fast, they keep a certain number of images in a buffer while they write to the card at a slower speed. When the buffer fills up, the shooting speed slows to the speed the camera can write to the card. If you get a card with a write speed close to the (raw file size x frame rate), you'll get the best result your camera can deliver.

Your camera specs will tell you it's requirements. Going a little over that number is probably wise. Going way over is a waste of money, unless you think you will be upgrading to a higher performance camera in the near future.

Right. Card makers are not going to under-rate their cards, but they might give them ratings that are a bit optimistic.

In my Nikon D-600 I have two SD cards both are San Disk Extreme Pro's and will write at 95MB/sec and are Class 10's with a capacity of 64GB's. Since I use both cards at the same time (one for RAW and one for JPG fine) I've never had a problem with buffer back-up.; I always shoot in burst mode, I find it easier to delete what I don't want than go back and set-up another shot...

I never use less than a class 10 and have never had an issue with buffering or transfer speed.

I'm a little late here, but that's the best choice as the D7100 writes to the card at 99mb/s. That's the card I got for mine. The only faster card will cost you a mint.

TY ...... glad I made a good choice :D Hopefully after a few setbacks I can get to try out the new camera this weekend.

But what about uploading to the computer? Faster writing means faster reading, so it can make sense to use a card faster than your camera needs.

A Nikon D7100 has a write speed (to the card) of 99mb/s; the read to the computer is however fast your card can "dump" it into it, i.e. USB2, USB3. A SanDisk Extreme Pro 32GB has a read/write speeds of 95/90mb/s respectively. I purchased one at B&H for $49.95. The write speed of this card is 4mb/s slower than the write speed of my camera. It is the fastest Class 10, UHS-I card made. However, I don't think paying $80 more for a UHS-II card (SanDisk Extreme Pro 32GB) to obtain that 4mb/s is justified - at least not in my wallet.
