Brand: Western Digital · SKU: WUH721414ALE6L4 · MPN: 0F31284 · Category: Storage
The Western Digital Ultrastar DC HC530 WUH721414ALE6L4 is a high-capacity 14TB enterprise-grade hard drive designed for public and private cloud environments, hyperscale storage, and massive scale-out data centers. Built on the fifth-generation HelioSeal technology, this drive uses helium instead of air to reduce internal friction and turbulence, resulting in lower power consumption and higher reliability. It features Conventional Magnetic Recording (CMR) technology for seamless integration into existing enterprise applications without the performance overhead of SMR. With a 7200 RPM spindle speed and a large 512MB cache, it delivers sustained transfer rates up to 267MB/s. The '6L4' model specifically denotes a SATA 6Gb/s interface, 512e format, legacy Pin 3 configuration (no Power Disable support), and standard Base (SE) security. It is rated for a massive 550TB per year workload and an industry-leading 2.5 million hours MTBF, making it ideal for 24/7/365 heavy-duty storage workloads.
