Does it need a backplane or controller?

No. It is a passive bracket, so each drive connects with its own SATA data and power cables to your motherboard or controller.

It takes 2.5-inch SATA hard drives and SSDs from 7mm to 9.5mm thick, up to four of them.

It needs one standard external 5.25-inch bay. Many modern cases omit that bay, so check your case first.

Does it cool the drives?

Yes. It can stand as a stackable drive organizing rack on a desk or shelf.

The bracket, a user manual and mounting screws.
