I thought it was the other way around: that most Linux filesystems (by 
which I mean ext2) and NTFS had 1K or 0.5K blocks, and that Windows FAT 
filesystems had big (generally 4K to 16K) blocks.

ReiserFS is the default with SUSE 8.1 which I've just installed.  Oh yes 
... hey folks, I've just made the switch from Windows to Linux.  Played 
with RedHat and Debian a couple of times in the last few years, but now 
I think it's a permanent switch.

My Windows ME (successor to 98SE) had a single 15 GB FAT-32 partition, 
and it uses 8 KB blocks.  On that, FG scenery was eating large chunks of 
my disk space.  I think FAT-32 is capable of using small (0.5K or 1K) 
blocks but is not configured to do so because the FAT itself would be 
big and therefore slow when following the block chain in large files.
