Yes, NTFS compression isn't generally slow when just reading
sequentially.  Slow operations are seeks, writes and even appends.

I know a company who used NTFS compression to store transaction
records in a POS application.  Tests were done with small data
sets.  When they went to production, they had to quickly revert
installed systems to uncompressed storage.  Apparently, appending
a transaction to the journal was a linear operation :-)

I don't know for sure, but JFFS2 shouldn't suffer from this
problem.  Using it on a 2MB flash, I can't test it with large
files :-)
