Originally posted by Frosty Many thanks for that Vincent that was very helpful, I can save money with no loss of speed then :-) Do you happen to know what the difference between the Sandisk Extreme and Extreme III , and also the ultra range is, is just a speed thing again which with the K100D I can safely ignore ?
SanDisk has the details on their own site:
SanDisk Extreme SDHC - notice these are the latest 30Mb/s Editions - that has to be a read speed.
These are rated as Class 10 which means minimum write rate of 10 Mb/s.
SanDisk Extreme III SDHC - again these are marked as 30Mb/s Edition - so what's the difference between the III and the above?
Class 6 - so write speed has to be >6Mb/s but <10Mb/s
SanDisk Ultra SDHC - notice it is marked 15Mb/s - this has to be the read speed - the Class 4 means it has a minimum write speed >4Mb/s but <6Mb/s (otherwise they could call it a Class 6).
The Ultra series would do fine in the K100D.
But so would any Class 4, Class 6 or even Class 10 and there are plenty to choose from - just choose a well known name and buy from a reputable/reliable vendor - and you ought to be fine.
Buying and paying for a more expensive "fastest" card is unlikely to show any advantage in the K100D - other than uploading via a fast card reader - then it's not really the K100D going any faster is it?
