Serial-attached SCSI (SAS) is a type of interface used to connect storage devices to servers. It is a high-performance interface that supports faster data transfer rates than other storage interfaces. SAS uses a point-to-point architecture, which means that each storage device has its own dedicated connection to the server. This eliminates the need for a shared bus, which can cause performance issues and reduce reliability. SAS also supports multiple protocols, which allows it to be used with different types of storage devices, including hard disk drives, solid-state drives, and tape drives.

The HPE 861683-B21 Hard Disk Drive features Advanced Format 512e technology. This technology increases the capacity and performance of the hard drive by using larger physical sector sizes. Traditionally, hard drives used 512-byte sector sizes. However, Advanced Format 512e uses 4K sector sizes, which allows for more efficient use of space on the hard drive. This technology also improves the error correction capabilities of the hard drive, which can improve data integrity and reliability.

The HPE 861683-B21 Hard Disk Drive is available in a small form factor (SFF) size. SFF hard drives are designed to be more compact than traditional hard drives, which makes them suitable for use in compact servers. The HPE 861683-B21 Hard Disk Drive has a form factor of 2.5 inches, which is smaller than the 3.5-inch form factor used by traditional hard drives. This allows for more hard drives to be installed in a server, which can increase the overall storage capacity of the server.
