An enterprise-class server internal hard drive with a capacity of 12,000 GB (12 TB) from the Ultrastar DC HC520 3.5" HDD family of 2021 models, which includes 5 models with SAS/SATA3 interfaces and a 512e/4Kn sector size. It is a high-quality enterprise-class drive, the design and firmware of which are optimized for solving the problems of long-term storage of information in RAID disk arrays with a large number of HDDs (for example, in enterprise-class servers or data centers, in 24/7 mode).

Thanks to the CMR magnetic recording method, a platter rotation frequency of 7200 rpm, a high-speed controller and an impressive 256 MB cache, this drive demonstrates high performance, excellent reliability and moderate power consumption. The WD Ultrastar DC HC520 HUH721212ALE604 hard drive is based on a helium-cooled design filling the hermetic block. The low density of helium, which is 7 times lighter than air, significantly reduces friction losses of magnetic plates and reduces the impact of gas flows on the accuracy of head positioning. The standard SATA3 interface is used for connection, so the drive can be installed in multi-purpose PCs and workstations.
