I browsed your article and made it to this page (http://pocketpcmag.com/forum/topic.asp?TOPIC_ID=17921) which it said had some benchmarks, but I only saw lots of information on formatting.

While nobody would dispute the fact that formatting makes a difference, I didn't see any hard firm numbers showing the differences in performance on a fragmented file system vs. an unfragmented file system.

Are they there somewhere?
Well, I have done quite a few benchmarks with both the above-mentioned Loox - the 30-times speed difference, for example. I've also made intentional fragmentation by copying hundreds of small files into my iPAQ 2210's FS, deleting half of it, recopying, redeleting some other half of it, and then, benchmarking the copy a big file to the above-way fragmented FS.

You can also try the same - just benchmark a long (at least 15-20 Mbytes in size) file transfer over ActiveSync to the File Store; then, defragment the filestore and do it again. Most probably, you'll see a performance (speed) increase, which can be pretty dramatic if your FS was heavily fragmented.

BTW, I've updated the article in the meantime - simply moving all the files to, say, your desktop computer and copying back will do the trick. You don't even need to format the File Store.

EDIT: sorry, my second word should have been 'have', not 'haven't' - I haven't read the answer before senfding it
