Kingston SD 512MB - Dealing With Other Disadvantages
(Page 2 of 3 )
For the other two disadvantages (storage capacity, price), Kingston has pretty much erased them by putting their large manufacturing ability behind SD (they also make CF cards). With the efficiency of scale that smaller flash memory providers don't have, they have brought the price of their SD memory within $5-10 of comparable CF densities for the base speed cards. The "ultra" 8-9MB/s high speed versions of both platforms are around the same cost.
The one we are looking at today is just a base speed model. This means its not an optimal choice for cameras that need speed in the card for continuous shooting. Other than that, the performance of the card won't affect use for playing back audio or visual media; anything that a typical PDA is actually capable of decoding will be slower than the maximum transfer rate of the card.
Where you will notice a difference is loading to and reading data from the card. Filling it with music for an MP3 player or PDA, or video, or pictures is slow and painful. The same goes for transferring from it. If you are going to continuously empty and fill, it would be advantageous to get a faster one as well.
