Does anyone know if the expander can be an eSATA connected RAID box, or possibly even a Drobo S? From what I understand, the RAID controller in such a box should mask the RAID nature of the internal array, and present to the Gateway just a single large eSATA drive.
If this is the case, and the RAID box is configured for fault tolerance, such as RAID 1 or 5, could a failed drive be replaced and after the RAID controller rebuilds the array, no data would be lost? If so, long term storage of TV shows could survive a drive failure. But, I guess if the gateway failed and was replaced, all would be lost anyway. Hopefully gateway failures would be less frequent than drive failures.
Also, in the case of the Drobo S, one could start with just two drives and add capacity to the array as needed. The box will accept up to five drives in any mixture of sizes, speeds, or manufacturers.
Is all of this just wishful thinking? Is there something about the gateway that would prevent the use of such a configuration.
Many thanks for your thoughts.
