Serial Attached SCSI speeds up to 12 Gbit/s. The physical SAS connector comes in several different variants: "Nearline SAS" (abbreviated to "NL-SAS", and sometimes called "midline SAS") drives have a SAS interface, but head, media, and rotational speed of traditional enterprise-class SATA drives, so they cost less than other SAS drives. When compared to SATA, NL-SAS drives have the following benefits: Serial Attached SCSI In computing, Serial Attached SCSI (SAS) is a point-to-point serial protocol that moves data to and from computer-storage devices such as hard drives and tape drives. SAS replaces the older Parallel SCSI (Parallel Small Computer System Interface, usually pronounced
Parallel and counter parallel Parallel and counter parallel In music, a parallel chord (relative chord, German: "Parallelklang") is an auxiliary chord derived from one of the primary triads and sharing its function: subdominant parallel, dominant parallel, and tonic parallel. The term is derived from German theory and the writings of Hugo Riemann (see: Riemannian theory). For example, the major and and minor and . The parallel chord (but "not" the counter parallel chord) of a major chord will always be the minor chord whose root is a minor third "down" from the major chord's root, inversely the parallel chord of a minor chord will
