Serial Advanced Technology Attachment, also known as Serial ATA or SATA, enables mass storage devices, such as hard drives and optical drives, to communicate with the system board using a high-speed serial cable over two pairs of conductors.

SATA ports on the system board
Connect your hard drives to the correct SATA ports to ensure that your computer functions correctly.
To install a single SATA HDD into your computer, connect it to the lowest-numbered port (such as SATA0 or SATA1) on the system board. Then connect the optical drive to one of the other ports.
To install multiple HDDs and install the operating system on only one drive, use the lowest numbered port on the system board (such as SATA0 or SATA1) for the drive with the operating system. Then use the next lowest numbered port for the second drive, and so on.
To install multiple hard drives with RAID mode to increase storage space or create a backup drive, connect one of the drives to the lowest numbered port (such as SATA0 or SATA1). Then connect the remaining drives to ports on the same controller.
Serial ATA (SATA) controller modes determine how the hard drive communicates with the computer. You can set a SATA hard drive to function in one of three controller modes: IDE, AHCI, or RAID. Enabling RAID mode also enables the AHCI features.
HP recommends setting the SATA controller mode before installing the operating system. Changing the mode after installing the operating system can prevent the system from starting.
Use the following steps to access the BIOS to set the SATA controller mode for a hard drive.
Download HP PC Hardware Diagnostics UEFI to resolve any error message that is displayed when you set up the SATA controller modes.
