| Can someone please expalian to me the difference between different compact flash cards. I am primarily interested in knowing why a lexar media card with say 512 and write acceleration technology is faster and much expensive than say a 1G sandisk Ultra II? |

Interestingly, many of the Sandisk UltraIIs are *faster* on card-to-computer transfer than the Lexar 80x cards. See this page. The Sandisk cards also have a better reputation overall. No card is immune to failure, but the Lexar cards have had issues. They do seem to have more issues when used with Canon cams.

| So Kirbic does the camera buffering control how fast the images are written to the card or does the card have something to do with it as well? Or does the write speed only have bearing on the card to computer transfer? |

Write speed will affect how fast your camera's buffer is cleared, so there is some effect on camera performance. How much difference depends on your camera's design. For most DSLRs, you'd be hard pressed to perceive the difference between a card that writes at 10MB/s and one that writes at 11MB/s.
In order for the faster card-to-computer rates to be "visible" to you, you need a very fast card reader. The USB2.0 models typically don't show up the differences, but FireWire readers (like the Lexar RW019) do. Again, how important is 10% in transfer speed? Ony you can say.

I have a 4G microdrive that is so slow, I can do my nails after a 4 frame burst. I use it only for studio shots and really old people.
I have 1G 80X Lexar that I use for all sports, kids, newspaper stuff, etc. My Sandisks are almost as fast but they are regular ones. Someday, I'll upgrade but I'll never buy another 4G Microdrive again.
Writing to my harddrive (450 RAW images) is so slow with the 4G microdrive I tend to do it overnight. Its just slow. Painfully slow even considering the # of frames. |
