Here's my matching XO's figures just for comparison:

df -m reports 1024 blocks, 479 used, 546 available, 47% used.
du -ms in the datastore directory reports 83Mb

I'm assuming the patterns of file/block use may also be a significant  
speed factor (not just total available space), as jffs2 has some  
interesting behaviours to deal with flash wear level and other need  
flash maintenance.
