What is this SATA connector with no seperation

[suki300me]

I bought few 3TB Hitachi internal HDDs off of eBay but once I got them, they had this weird looking SATA connector where there is no seperation between data and power inputs (see pic)
Can anybody tell me what this is called? So I can search for an adapter cable?

SATA Attached SCSI (SAS).

You cannot connect a SAS drive to a SATA port, but you can connect a SATA drive to a SAS port.

You'll need a PCIe SAS controller.

If the seller did not state its a SAS interface, maybe you could return them. SAS drive can be found in servers.
