400-BEKK Dell 14TB 7.2K RPM SAS-12GBPS 512MB 512e LFF HDD

The 400-BEKK is a Dell-branded 14TB hard drive that operates at 7200 RPM (revolutions per minute). It has a SAS (Serial Attached SCSI) interface, with a 12 Gbps data transfer rate. The 512e in the model name indicates that the drive has 512-byte emulation, which means it is compatible with systems that use 512-byte sector sizes, rather than the newer 4K sector sizes. The LFF in the model name stands for “large form factor”, which means that the drive is a 3.5-inch size, as opposed to the smaller 2.5-inch form factor. This hard drive is compatible for use in servers and storage systems. 512MB of buffer cache memory is also featured in the drive.
