AFAIK OCZ Vertex 2 does not use volatile DRAM cache but non-volatile NAND

There has been previous discussion about this:

"I'm pretty sure that all SandForce-based SSDs don't use DRAM as their
cache, but take a hunk of flash to use as scratch space instead. Which
means that they'll be OK for ZIL use."
So, OCZ Vertex 2 seems to be a good choice for ZIL.
There seem to be quite a lot of blind assumptions in the above. The
only good choice for ZIL is when you know for a certainty and not
assumptions based on 3rd party articles and blog postings. Otherwise
it is like assuming that if you jump through an open window that there
will be firemen down below to catch you.
