Cause i am start used from class 3, class 6, now class 10 and the 15, 30, 45mb/s and now 95mb/s still works great..
Small is good any laptop got built-in SD card reader, that is more advantage of SD Card User.
The CF Card for backup only
CF faster but definitely more fragile, esp for the reader.
SD is definitely the future esp with the new UHS cards.
Well, if you think abt it, you would be more likely to mix up SD card slot compare to CF's as the MMC slot and MS slot looks similar to it. CF reader on the other hand, are more vulnerable greeting damaged by CF card as misalignment of pins can still happens even if you slot your card in at the correct orientation. A bent pin is all you need to spoilt ur CF reader. Im slowly converting all my cards from SD to CF due to camera usage, SD is usually my backup slot for two slots camera.
first - CF card is no longer faster as compared to SD card, they have the same read and write speed nowadays.
Second, CF card is definitely not as fragile as SD card, reason being the contact points of the CF card are not exposed, while SD card's contact point is exposed and might be subjected to oxidation and stuff like that.
I cannot say that SD card is definitely the future because there are other format coming out. Who knows, SD and CF cards will both be replaced in near future.
Anyway, I reckon there really is no need to be worried about all these things. Just see the amount of people enjoying their SD card would be enough proof that there really is not too much problem at all.
However, there really is not much to write home about as compared both. Just use whatever your camera support and whatever you like (as long as your camera supported it) and there is no need to worry about any other things
CF card may still be electronically superior than SD cards.
Looking at the Rob Galbraith tests, the fastest CF cards are faster than the faster SD.
But of course, for mere mortals like me with limited resources, I doubt I need the fastest for my everyday usage. So I let my wallet vote - SD card has the best bang for the buck in terms of balance between speed and capacity.
As currently my camera accepts both cards, I'm think of getting a CF to store raw and SD to store jpg (utilize both slots when using camera) as I'm also holding on to a iPad, I can conveniently insert the SD card to the iPad to extract the jpg photos for viewing and still have the CF to store the raw if I need to alter the photos later.
Anybody knows where to get cheap 32gb SanDisk Extreme Pro CompactFlash Cards 90MB/s? Think of getting it to go with my 16gb Extreme Pro SD cards 30MB/s.
