SATA
Definition
Serial ATA, a host interface for storage devices.
Detailed explanation
SATA means Serial ATA, the host interface commonly used by hard drives and 2.5-inch SSDs. AHCI is a standard controller programming model for SATA, while vendor RAID modes can expose disks through another driver layer. Link speed, command queueing, cabling, and device firmware are separate parts of the path. The link negotiates between host and device generations, while NCQ permits multiple outstanding commands. SATA identifies the transport; it does not specify whether the media is magnetic or flash. M.2 describes a form factor and can carry SATA or PCIe/NVMe signals depending on the socket and device.
