ESXi - Span Datastore across multiple SATA HDD, or Create OpenFiler VM and use iSCSI

Hi gang,

I have noticed that in ESXi 5 it is possible to create a datastore on a SATA drive and then expand it on to more drives. I am wondering what sort of performance this is likely to give vs creating an openfiler VM, adding all the discs into an array and then creating an iSCSI target to use for my other VMs?

I have attached the screenshot of a 6TB datastore created by expanding across 6 x 1TB HDD.

This is for a non critical server, so no need for comments regarding redundancy.

Thanks for the help!
