Which of the following is true of SAS compared to SATA?

SAS (Serial Attached SCSI) is designed for enterprise environments and uses differential signaling, allowing for longer cable lengths of up to 10 meters (32.8 feet) per segment. In contrast, SATA (Serial Advanced Technology Attachment) is primarily for internal PC use and supports much shorter cable lengths, typically limited to 1 meter (3.28 feet).

Both SAS and SATA are primarily designed for storage devices like hard drives, SSDs, and optical drives, not for peripherals like scanners and printers, which typically use USB or Ethernet.

SAS generally has a faster interface than SATA, with each SAS lane offering higher throughput than a single SATA link, especially in contemporary generations.

SAS typically uses lower voltage differential signaling (LVDS) for improved signal integrity over longer distances and reduced power consumption, whereas SATA generally uses higher voltage single-ended signaling.
