DSLR & SD cards - does speed matter
ps56k
and came across some info regarding different speeds/performance of flash
cards
when used with digital cameras - ie, higher end DSLR
http://en.wikipedia.org/wiki/Secure_Digital_card
I was wondering if you have tried or noticed any shoot & save speed
differences
when using different "speed" cards - not size, but "class" ?
---
SDHC cards adhere to the SD Speed Class Rating specification
which defines a minimum sustained transfer speed and use the FAT32 file
system.
The SD Speed Class Ratings specify a minimum sustained write speed for SDHC
cards:
Class 2: 2 MB/s;
Class 4: 4 MB/s;
Class 6: 6 MB/s;

It can make a difference on the higher end pro-sumer DSLRs and up.
Certainly so when you're talking four-figure prices - Single digit Nikons
come to mind most strongly.
No personal experience though - this poor D50 user has class two cards and
likes them.

I rather suspect that your figures regarding card speeds are wrong. 6Mb/s
is a rather slow speed.
Many cards have speeds up to 45Mb/s, (Sandisk Ducati for example). I also
suspect that while the actual speeds acheived will be a bit below the makers
quoted max speed, they will still be well above 6 Mb/s..
Most of the higher end DSLRs use Compact Flash not SD or SDHC.

will not make the camera any faster. If the camera is faster than the
card, then a faster card WILL result in faster saving. How to know?
Try before you buy if possible.
