<< Does a RAM Disk become fragmented? >>
Yes.
<< If so, how to avoid it in the OmniGo? >>
You could run something like Norton's Speedisk or DOS's
defrag on an SRAM card in a thincard drive on a PC or notebook
computer... but see the next answer...
<< Can it affect performance? >>
Nope. It's the mechanical read/write head traveling
around over a physical disk that slows down file access on
a disk drive. A RAMdisk has no such physical aspect, so
the difference in access time between a fragmented and an
unfragmented RAMdisk is negligible.
