Hello,

Scouring online prices it looks like Sandisk Extreme cards are almost double the cost of normal Sandisk cards (the blue ones). If I'm shooting with a D90, will the additional speed of the Extreme cards give me any benefit?

Thank you.
 
Only when you put them into the card reader, and you'd need a firewire800/USB3 to get any real benefit.
 
You can get a sandisk extreme on amazon for about £8.99 for an 8GB or about £12 for a 16GB, much cheaper than anywhere else I can find, if you did want an extreme one without the high price tag.
 
It'll depend on which cards specifically you're talking about. The D90 is 12MP, so for a start, depending on whether you're shooting RAW or JPEG, let's pluck some numbers from the ether and assume each shot is between 5-10MB in size?
Now a class 4 card like this is only guaranteed to give you 4MB/s a sec sustained writes, whereas this one which is albeit only class 6 is rated to 20MBs, so could *potentially* be a lot faster.
This is not to say it definitely will be. It's been my experience in the past that some Class 4 cards can obtain exactly the same speeds as other Class 10s. But the speed rating is there as somewhat of a guarantee. And certainly on Amazon, which is where I buy the majority of my media from, there's usually negligible difference in price.

One thing I will just add though, for your needs there's no point buying the Extreme *Pro* range. These go up to 90MB/s transfer rates now, but there's very few cameras that will leverage the extra speeds that the UHS-1 spec offers.
