400-BEKI Dell 12TB 7.2K RPM SAS-12GBPS 256MB 512E LFF HDD

The 400-BEKI Dell 12TB HDD uses the SAS (Serial Attached SCSI) interface, which is a high-speed data transfer interface that is commonly used in enterprise-level storage systems and servers. SAS is a point-to-point interface, which means that each device has its own dedicated connection to the host, rather than sharing a common bus.

SAS-12GBps refers to the data transfer speed of the SAS interface, which is 12 gigabytes per second (GBps). This means that the hard drive is able to transfer data at a maximum speed of 12GBps. This high data transfer speed allows for faster data access and improved performance in demanding applications
