Compact flash type 1 and 2 difference?

[slipper]

ok so i searched google but all i could find is the physical difference and the current draw difference but i was also curious if there is any performance difference. i noticed on ebay CF Type 1 cards cost much less than CF Type 2 so i was just curious.

As far as I'm aware, only the CFII cards support the higher speed writing but wikipedia suggests that aside from the differences you've noticed, there's no real difference.

type II are thicker, iirc and support higher capacities. also microdrives are type II sized.

Would it make a big difference in write performance between regular CF cards and "high speed" CF cards? I just purchased an Olympus E-300 and i bought it because its affordable. Nor do i want to blow my money on a ridiculously expensive CF card if its not extremely important.

you should google for benmarks/reviews of the card. someone out there on the internet tested it. the answer to your question is yes though, high speed cards make a difference when taken a lot of pictures rapidly. however, if you one of those people who just take a few pictures at a time them, i don't see a point.

Faster CF cards

Higher resolution cameras seem to benefit from faster cards since there is more information being written to the card. You can try searching this website for CF speed info.

Hope this helps,

ok so i bought a 3gb hitachi microdrive. according to some online sources it has a write speed of 7mbps. the Sandisk Ultra 2 that i was looking at has a write speed of 9mbps and the Extreme 3 is 20mbps. is 7mbps decently fast? any downsides to microdrives?

it depends on the memory bus of your camera. if your camera can only sustain 3MBps write speed, you wouldn't notice any advantage of the faster CF cards, except for improved battery life. you can find out your camera's memory bus speed by checking out its review at http://www.dpreview.com
edit: an e-300 seems to get ~3MBps writing JPEG files and ~5MBps writing RAWs
