Can the Seagate GoFlex Thunderbolt Adapter STAE121 be used with a 3.5" drive?

2.5 and 3.5 SATA drives share the same type/size of connectors. so I can't imagine it wouldn't work. Worth a shot, in any case. All those drive docks like this one: https://eshop.macsales.com/item/NewerTech/VU3ESFW8/ support both 2.5 and 3.5, using the same connector inside the dock.
