Nikon d3000 sd card HELP please

[Nixoncarps]

Hey you probably get this all the time I have taken up automotive photography for a hobby with some friends of mine and do a lot of rolling shots but find the sd card takes a long time to save / buffer the image someone told me the bigger the MB/s the quicker it takes to save the image!? Is this true!?
Thanks for your help

Yes it is true. Not all SD cards are the same. For stills, Nikon recommends at least a class 6 card. But since class 10 cards are already common, might as well get one. Now there are two common additional types of class 10 cards 30 MB/s and 45 MB/s.

A brief description of SD card speeds.

1) Speeds are initially rated from Class 1-10 with 10 being the fastest.

2) Not all SD cards in the same class have the same speed though. A UHS (ultra high speed) SD card is faster than a regular SD card which AFAIK is 10 MB/s (anyone can correct me) UHS cards has speeds of 30 MB/s, 45 MB/s and up to 95 MB/s.

There is a newer class though not common and presumably more expensive which is the UHS-II card.

You don't really need the fastest and this came bundled with my D3100.

This I can say that it works well even for continuous shots or video on my camera.

But I would recommend this if you can swing it.
