Ok, I'm getting a little confused here.
Just looking at investing in some CF memory cards for my 5D Mark 3.
Now I understand that it has a duel CF and SD slot and that should I use them both then write speed is slowed to that of the SD card.
Now if I use CF only, does the speed of my card affect the burst performance or not? or does it just limit how fast it can clear the buffer, meaning I can run a shorter burst as it fills up to quickly?
Secondly, Just been looking at the difference between UDMA and UDMA 7, apparently 133mb/s against 167mb/s, so if the card is rated at 90mb/s does it really matter which UDMA it is?
Thirdly, looking at the transcend specs for their cards and the write performance increases with the size of the card,
Read 90 MByte/s, Write 60 MByte/s (64GB);
Read 90 MByte/s, Write 45 MByte/s (32GB);
Read 60 MByte/s, Write 30 MByte/s (8~16GB)
is this the same as sandisk as i cant seem to see in their specs.
I also read somewhere that using less that 16 gig uses one controller where as 32 and above uses 2 controllers, is this correct?
Also recommendations on cards are welcomed
Thanks
