Drives are linked by cables called SATA cables, these send data through the motherboard
Everything is connected to the motherboard. Everything other than hard drives and disc drives would be directly on the motherboard.
SATA cables.
Install the motherboard first. The drives will have wiring harness to connect to the motherboard.
The motherboard holds most of the essential circuitry needed for the computer. It contains the CPU, the chipset, the buses, the memory, voltage regulators, the BIOS, the CMOS battery, and various controllers. The motherboard may or may not have integrated graphics. If not, the machine will need a separate video card.

Without a motherboard no computer would function ! It is the main circuit board that holds the processor, memory modules and any expansion cards such as Graphics card, Modem card, Network card etc. Any harddisk drives, CD/DVD drives and floppy drives are connected to and controlled by the Motherboard. As are a keyboard, mouse, printer or scanner.
Technically it's the other way around, everything (keyboard, monitor, printers, hard drives, etc.) are connected to the mother board.
SATA, or serial advanced technology attachment, connects the motherboard to hard drives and optical drives. This cable is inserted into the SATA slot on the motherboard.
It wouldn't be a SATA motherboard if you couldn't connect SATA drives to it.
The IDE/ATA bus controller manages the flow of information between the hard drive and the rest of the computer. At this point in time, The IDE/ATA bus controller is typically built into the motherboard so hard drives can be connected directly to the motherboard.
