Capacity and interface
The HGST Ultrastar HUH721010AL4200 is a 10TB 3.5-inch internal hard drive with a SAS 12Gbps interface spinning at 7200 RPM. It is built for enterprise storage arrays, network-attached storage and servers that demand high capacity and sustained throughput.
Host compatibility
Verify that your system provides a SAS 12Gbps backplane or controller and a 3.5-inch drive bay with the standard SAS power and data connectors. The drive uses a 4Kn sector format, so the operating system, RAID controller and filesystem must support 4K native sectors.
Thermals and power
Designed for continuous operation in multi-drive enclosures, the drive runs at typical enterprise temperatures with standard forced-air cooling. Acoustic output is consistent with 7200 RPM helium-sealed mechanics under normal access patterns. Power draw follows the SAS 12Gbps specification for 3.5-inch enterprise drives.

Questions about this item
Does the 10TB Ultrastar ship with mounting screws or a SAS cable, or must they be purchased separately?
The drive is supplied as a bare 3.5" unit; mounting screws and a SAS data cable are not included and must be sourced separately.
Should I choose the 12Gbps SAS model or the 6Gbps version for a server backplane that only supports 6Gbps?
The HUH721010AL4200 runs at 12Gbps but negotiates down to 6Gbps automatically, so it works in a 6Gbps backplane without any configuration change.
What does the 7.2K RPM rating mean for sustained throughput in a RAID array?
At 7200 RPM the drive delivers consistent sequential speeds suited to RAID workloads such as NAS, SAN and transaction processing.
