No no G. What I had in mind was testing with files from my DS. First with PEF files. Then with my regular workflow using compressed DNG files, all files going thru same software.
I believe this will tell me something about how my software/computer system will perform with the larger files from the K10D. Not an accurate test, but it will provide me with some information I believe, since the size of compressed DNG from K10D is almost the same as uncompressed PEF from the DS. Don't you think? I explained myself bad yesterday. Sorry about that. My system (read brain) was overheated, after a bad day at work.

(going a bit OT) Only if you're processing them with the same software. The only three software packages that can process K10D PEF files are Pentax Photo Lab (slow as molasses no matter what you toss at it), Silkypix (reasonably speedy), and RAW Developer (Mac OS X only, pretty darn fast). PentaxLab converts PEF to DNG (glacially slowly, then at an inflated 21Mbytes apiece rather than *just* 16 or so), and then you can use Lightroom or Camera Raw, both of which outperform Pentax Lab by about two orders of magnitude on speed (on my computer, anyway). I did a test: had Camera Raw batch process 100 K10D DNG files to full resolution PSD files. Took just a little over 4 minutes. Same test with *ist DS PEF files (about 30% smaller) took 3.5 minutes. The real difference is in the output IO ... a 10Mpixel PSD file is about 40% larger file size than a 6Mpixel PSD file.
