A technician is setting up a physical server that will be used to store sensitive data. The technician plans to set up the internal hard drives in a RAID 5 array for redundancy. Which of the following

SAS (Serial Attached SCSI) is an enterprise-class interface specifically designed for server storage, offering superior speed, reliability, and support for advanced features like dual-porting, which are critical for high-performance RAID arrays storing sensitive data. Its robust design makes it the best choice for internal hard drives in a server environment.

USB (Universal Serial Bus) is an external interface for peripherals and consumer devices, completely unsuitable for internal server hard drives or RAID configurations.

SD (Secure Digital) cards are flash memory cards used in portable electronics and lack the capacity, speed, and durability required for server hard drive storage or RAID.

eSATA (external Serial Advanced Technology Attachment) is an external interface for connecting SATA drives, mainly for consumer-grade external storage, and does not provide the enterprise-level features or reliability of SAS for internal server RAID.
