We've tried DOC, solid state drivers and the IDE <-> CF solutions. We had bad reliability problems with DOC2k, which have evidentally been corrected. We also had availability problems with DOC2k as well as price problems (they are 20% more expensive than CF + IDE adapter). We found that the solid state disks worked great, but were too expensive per megabyte in the flash versions and harder to get than CF. We use the CF <-> IDE adapter. They are cheap for us to make (on the order of $20 for the custom units we make), and allow us to use the CF cards which are the cheapest at the moment. We see that we can get the CF + IDE Adapter for on the order of $150 for 64MB, while the DOC is (was) stll running $190+ with 3 month lead time. Various commercial IDE <-> CF adapters we've found run in the $40-$50 range. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-small" in the body of the message
