Early hard disks were connected to IDE, SCSI, etc. With the development of hard disk technology, these connection types have disappeared. The current mainstream hard disks use SATA, SAS, PCIE, etc. Which of the following statements about SAS and SATA is correct?
A . In terms of the physical layer, SAS connections and SATA connections are compatible with each other. SATA hard drives can be used directly in a SAS environment, and SAS can also be used in a SATA environment.
B . At present, most mobile hard drives for home use are SAS connected, while SATA connected is for enterprise-level applications.
C . SAS is a new generation of SCSI technology that uses parallel technology to obtain higher transmission speeds and improves internal space by shortening the connection lines.
D . SAS can meet high-performance, high-reliability applications, while SATA can meet large-capacity, non-critical business applications.
