Lots and lots of experience with ZeusRAMs.  Nice devices, and the SAS capability makes them one of the few good choices for a shared storage cluster.

DDRdrive's are interesting and blazingly fast, but suffer from their form-factor and lack of clustering capability.  The lack of onboard power protection makes them a poor choice if you cannot meet their requirement for an external reliable power source.  (They have an external wall wart with a small power cable going to them.  Not very enterprisey, but still damned fast.
