USB is widely available, but still a serial bus, so only a single request to a single memory stick per host controller is in flight at any one time. (Even with 8 USB ports it's still one controller.) 64x CF suggests custom hardware. If considering custom hardware it would be interesting to talk to semiconductor sales people, since 2 TB worth of flash chips is a decent size order even if it would be just one-off. Flash storage cost could come way down, trading for hardware development time and manufacturing cost of course. How will lookup work? #4 is sadly empty. Can lookup be parallelized? If not so much then seek time could indeed justify custom flash based storage (and also lookup?) hardware. //Peter _______________________________________________ A51 mailing list [email protected] http://lists.lists.reflextor.com/cgi-bin/mailman/listinfo/a51
