The rest of the system wasn't anything to write home about, it was just the two-level flash disk that caught my attention as a neat idea. I've also heard of systems where there's a smaller amount of SRAM used as a disk cache, with the intention again of reducing repeated write activity, but I don't know of anyone doing this commercially. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
