which memory card is suitable

following on from davidstewards thread about the new high speed sandisks it got me realising about my memory. i use a jessop 4gb cf card but i am having slow recording times eg. a 30 second exposure would take 30 seconds to write to memory card. and i wondered what would be most suitable for me, and what is best aswell for high speed shooting at 3 fps without filling up after 1 second.

all comments appreciated,

It's not the memory card that's the problem, you've got long exposure noise reduction switched on and it takes the camera approx the same as the shutter time to work it all out...
 
I don't think I'm going out on too much of a limb to say that most people consider the Sandisk range to be the best around. Their Extreme III or Extreme IV are fast, reliable cards - I use the Extreme III a lot (they're a lot cheaper than the IV) and don't have a problem.

It's worth noting two points though that you might want to think about in relation to your camera.
Most fast-burst shooting is buffered by the camera's internal memory so when you take a burst you can normally shoot until you fill the buffer, then this is written to the card. Here, the card speed only affects how quickly the burst is copied from the buffer to the card and so will help you start shooting again quickly but it won't help with the burst itself.

The other thing is that many cameras have a feature called long-exposure noise reduction. If you're shooting long exposures such as 30 seconds then it's quite common for it to take the same again to process it - the actual writing to the card will be much quicker than this! If you want, you can normally turn this feature off to speed things up.
 
ahh so i need to take the NR for long exposure off, i never use long exposure much but it does get slow.

i did hear somewher about the camera's buffer has for example 16mb so it can shoot 3fps and then they all have to transfer to memory card.

i am definitely getting some sandisk extreme cards at chrimbo, or i might wait until focus on imaging.
 
with long exposure noise reduction switched on, the camera takes the picture first then takes an identical picture without opening the shutter.

It then subtracts the second image from the first so reducing the noise in theory
