We tried all combinations of OCZ SSDs including their PCI based SSDs and they
do NOT work as a ZIL. After a very short time performance degrades horribly and
for the OCZ drives they eventually fail completely. We also tried Intel which
performed a little better and didn't flat out fail over time, but these still
did not work out as a ZIL. We use the DDRdrive X1 now for all of our ZIL
applications and could not be happier. The cards are great, support is great
and performance is incredible. We use them to provide NFS storage to 50K VMWare
VDI users. As you stated, the DDRdrive is ideal. Go with that and you'll be
very happy you did!
