I haven't seen this mentioned before, but the OCZ Vertex Turbo is still an MLC-based SSD, and is /substantially/ inferior to an Intel X25-E in terms of random write performance, which is what a ZIL device does almost exclusively in the case of NFS traffic.
ZIL traffic tends to be sequential on separate logs. But may be of different sizes.

In fact, I think that the Vertex's sustained random write IOPs performance is actually inferior to a 15k SAS drive.
I read a benchmark report yesterday that might be interesting. It seems that there is a market for modest sized SSDs, which would be perfect for separate
logs + OS for servers. http://benchmarkreviews.com/index.php?option=com_content&task=view&id=392&Itemid=60 -- richard _______________________________________________ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss
