The spreadsheets with the performance metrics for both SSD's are here:http://public.me.com/ndlucas
They are both good performers in IOP/s with the Fusion IO edging out the OCZ on the smaller IO sizes.
Raw performance showed the OCZ was the clear winner.

With that out of the way, the question is now, which one makes more sense for your application and budget?
The 320GB FusionIO is priced in the $7000 range.
The 1TB OCZ Z-Drive R2 is in the $4600 range.
I have a feeling that FusionIO has enterprise support standing by, where OCZ does not. Maybe I am wrong, but that is the impression I get. For my purposes I will get an extra Z-Drive for a cold-spare while waiting for OCZ to turn around a replacement in the event of a failure.
