I did think of that but is a CF card faster than a good SAS or SATA
drive? Fastest ones I found have a top rating of 45MB/s. The one
battery backed NVARM card that showed up in a google search had a
peak rate of 533MB/s. The question seems moot though since FreeBSD
doesn't currently support them.
Thanks for your time,
