G-Speed ES supported Disk Drives

I just purchased a G-Speed ES off of eBay. And I would like to know what HDD are supported. And what is the maximum storage. i.e. 4 x 6 TB or 4 x 4 TB or 4 x 3TB, etc. I would like to get the maximum storage off of this device. This seems to be the latest mode. And comes with a 3Gb eSATA connection.

Hi @BLaurens,

Please be informed that Storage capacities up to 16TB per unit are scalable to 32TB.
