mydocs is on the emmc, which is nand-based flash memory. flash memory, unlike hard disks, doesnt have seeking, so there is no {very little} penalty for distributing your data across the 'disk'.

EDIT: whoops, what he said.

EDIT: also, when i say 'very little', i mean that it is very rarely convenient to have files' data neatly organized on the disk, e.g.: for un-deleting files. there is absolutely no performance gain whatsoever for defragging flash ever.
