Enterprise capacity for data centres
The HGST Ultrastar DC HC520 is a 12TB 3.5-inch internal hard drive built for enterprise storage arrays. It spins at 7200 RPM with a 256MB cache and uses a SAS 12Gb/s interface. The helium-filled design supports continuous operation in high-density server environments.
Not for desktop or workstation builds
This drive is engineered exclusively for server chassis and external storage enclosures that provide SAS backplanes. It will not operate in a standard PC motherboard or consumer NAS unit. Buyers who need a drive for a home workstation, gaming rig or single-bay enclosure should look elsewhere.
SAS 12Gb/s interface determines compatibility
The drive connects only via a 12Gb/s SAS port and requires a compatible controller or backplane. No other interface is present on the unit. Verify that your storage system accepts 3.5-inch SAS drives before purchase.

Domande su questo articolo
Should I choose the 12TB HC520 or a smaller HC520 model?
The HC520 series is offered in multiple capacities; the 12TB model provides the highest raw storage in a single 3.5" drive. Select it when you need maximum capacity per bay, otherwise choose a lower-capacity HC520 to match budget or redundancy plans.
What does the 7200 RPM rating mean once the drive is installed in a server?
7200 RPM is the spindle speed that determines baseline sequential throughput and average latency. In a server array it delivers consistent performance for mixed read/write workloads, supported by the 256MB cache and helium-sealed design.
What does the SAS 12Gb/s interface cap in practice?
The SAS 12Gb/s interface caps the host-link transfer rate at 12 gigabits per second. Actual sustained throughput will be lower and is limited by the 7200 RPM mechanics and 256MB cache.
