I tried today to connect my Drobo to an 2.5" disc and figured out that it is possible to use SATA extension cables.

the only thing I had to do is to modify the original connector a bit. The recessed grip had to be removed.


After that it was no problem to connect a 2.5" drive to the Drobo.
I thing that opens the possibility to use an cable to connect an external RAID enclosure with more than one SATA disc to a Drobo slot.
