More and more enterprises find themselves in a hybrid environment of traditional IT and modern IT. IT systems and technologies are rapidly iterating and transforming, making the stability and efficiency of storage platforms increasingly crucial. The key differentiators of Western Digital enterprise-grade HDDs lie in their high reliability, long-term operation, and high average MTBF (Mean Time Between Failures).
The Western Digital enterprise-grade WUH721818ALE6L4 HDD is primarily designed for large-scale data center storage needs, including medium and small enterprise servers, rack data centers, and storage clusters. Compared to typical computer storage HDDs, it offers significant improvements in stability and durability. The Ultrastar DC HC550 features two interfaces, namely SAS 12Gbps and SATA 6Gbps, with a 7200RPM rotational speed and 512MB cache. It boasts a seek time of 4.16ms and a maximum read speed of 257MB/s.
The WUH721818ALE6L4 utilizes a 9-disk design, with each disk offering 2TB of storage, achieving a storage density of 1022Gbits/sq.in and employing the EAMR (Energy-Assisted Magnetic Recording) technology. The Western Digital Ultrastar DC series, originating from the Hitachi brand acquired by Western Digital in 2011, is an innovative pioneer in the hard drive industry, featuring the most advanced technology in current HDD products.
The HC550 series, launched in 2020, introduces the ePMR (Energy-Assisted Perpendicular Magnetic Recording) recording method, differing from the MAMR (Microwave-Assisted Magnetic Recording) and HAMR (Heat-Assisted Magnetic Recording) technologies used in mainstream high-capacity HDDs. Western Digital states that ePMR reduces interference and lowers write jitter by applying additional magnetic field to the main pole of the write head. Additionally, Western Digital introduces the Triple Stage Actuator to enhance head positioning accuracy, allowing for more compact track layout on the disks.
The Western Digital Ultrastar DC HC550 series offers capacities of 16TB and 18TB, with each capacity available in both SATA and SAS protocols. The WUH721818ALE6L4 is the 18TB SATA version of this series. In addition to the shared advantages of the HC550 series, this HDD offers an extended operational lifetime of 2.5 million hours and 5 years of warranty. If you seek maximum storage capacity, consider trying out this data center-grade HDD.
