And at the low end of the market, has anyone tried this: http://www.acard.com/english/fb01-product.jsp?idno_no=382&prod_no=ANS-9010BA&type1_idno=5&ino=28 The Acard ANS-9010BA seems cheap and, if not plentifully available, at least available on ebay and amazon. It's battery backed and will auto backup to a CF card, which seems pretty cool for something that is cheaper than the big boys' toys. Sometimes cheap is good. Sometimes cheap is a disaster. :-) Has anyone discovered which camp this one is in, when used as a ZFS ZIL? Cheers, Stephen.
