repeating: 'Because I optimized *read* operations'

I'm tom, working at this time with Bart. Bart checked the stuff in.
take the time to search history.txt for 'tom'

maybe downright lazy, but http://www.drivesnapshot.de/en/ needs fast read, but never writes (trough the file system)

not necessary. Speed differences - be more specific You did yourself ;)
