Ultrastar DC HA340 8TB enterprise HDD
The Western Digital Ultrastar DC HA340 is an 8 TB internal hard drive built for enterprise and data-centre storage. It spins at 7200 RPM with a 256 MB buffer and uses the SATA 6 Gbps interface for host connectivity.
Suited for bulk storage arrays and backup targets
This drive fits 3.5 inch bays in servers or workstations that need high-capacity magnetic storage. It is not for systems requiring a 2.5 inch form factor, for environments that need solid-state latency, or for external enclosures without a 3.5 inch mount.
4Kn sector format requires host support
The drive presents 4Kn native sectors, so the controller, operating system and any RAID layer must all support 4Kn addressing. Without that support the drive will not be recognised or will report incorrect capacity.

- 8 TB capacity stores large datasets

Questions about this item
What SATA port speed does my motherboard need for the 600Mbps transfer rate of this 3.5" HDD?
A SATA-6Gbps port is required to achieve the 600Mbps data transfer rate of the Ultrastar DC HA340.
Can the 256MB buffer of this 7200RPM drive handle workloads from an older SATA-3Gbps controller?
The 256MB buffer helps sustain performance, but the 600Mbps transfer rate is limited to the 3Gbps link speed on an older controller.
How can I verify the 7200RPM spindle speed is active after installing the WUS721208BLE6L4 model?
Check the drive's reported RPM in BIOS or SMART monitoring tools; it should read 7200RPM for the Ultrastar DC HA340.
