i love that old ryobi cordless screw gun print ad of a guy standing on the wing of a flying biplane. the caption was: "there are two screws loose on this plane....we can fix one of them"

cool, i guess there is a slight difference. if you are getting 6~8 seconds at raw+jpeg, i'm guessing you are doing the large jpeg. i'm shooting at raw+1mp jpeg (smallest size) and still getting 8~10 seconds.

:bang: dang camera dealer, told me these were the best cards i could probably find

Just a couple thoughts here: I capture only DNG data, and this seems to busy the camera/blinking light for what has been posted already... about 3-5 seconds; and while the light is blinking, several captures are possible... I've never fired off more than the buffer can handle. Writing DNG only is far faster than both DNG and JPEG.

If you're saving smaller JPEGS, it just might take longer because the in-camera image processing engine must downsample the data. Have you tried the larger JPEG resolution and seen the same timing? Also consider whether you're using a coded lens, especially 35mm and "less": the vignetting corrections may also take more time to process. I have one coded lens, but turn "Lens Detection" to "Off" because it's 75mm. When saving JPEG, which colorspace did you choose, or did you leave it at the default sRGB? Did you tweak the contrast, saturation or sharpness, or did you leave these to "standard"? All of the above will effect JPEG writing "speed", and it's the JPEG that soaks the processor.

As for good and bad SD cards, I have but one brand and all 3 of them 2GB size. The lone Sandisk Extreme III I have does facilitate faster operation. I won't go 4GB because my maths aren't so good beyond 2GB, and only once did I store up greater than 130 files, all DNG. I then dump all DNGs to the computer, leaving the /dcim/leica100/ directory empty for next use. I formatted all of my cards first with a VFAT file system, then let the camera "format" them again. Once is all that's been done. Some card vendors place stuff on the card I will never need, so a VFAT format is always done to new media, in my shop.

On a side note: I wouldn't put anything in the card's /dcim directory, that's where we were instructed to place the 1.09 firmware for the upgrade and the camera just saw the file, upgraded the f/w and then /deleted/ the f/w file on the SD card. This directory may be a special location that the camera expects operating system data, not DNG or JPEG data, etc.(Me wonders if Gid's latest issue may have be caused by this sort of "filing" action?).

I'd try formatting the card VFAT. Let the camera format it again. Then start with lens detect off, and default processing at full res JPEG to see if the card is really thet slow.
