As new applications, use cases and connected devices multiply, Western Digital's enterprise-class hard disk drives (HDDs) remain critical for helping data center customers design more cost-efficient, scalable and sustainable infrastructure. When combined with the emergence of generative AI and the multitude of innovative applications it is enabling, the demand for high-capacity, low-power and reliable storage is poised to surge.

Western Digital leverages numerous technology innovations - ePMR, OptiNAND, UltraSMR and more - to deliver predictable capacity growth in scalable, highly reliable products. Western Digital is now shipping its new 10-disk 24 TB CMR HDD family for hyperscale, cloud and enterprise data center customers. Sampling since August, the new 28 TB SMR HDD is also ramping, adding to the company's SMR leadership position and momentum as its 26 TB SMR HDD exabyte shipments reached nearly half of its data center exabytes shipped in the first quarter fiscal year 2024.

When it comes to data, everything is growing - quantity, size, format, resolution, use cases, applications, value and more. As people and businesses look for solutions to effectively and efficiently store their data in the zettabyte era, Western Digital HDDs continue to play a critical role in delivering massive capacity, performance and reliability.

Extending its innovation and technology leadership across its portfolio, Western Digital today announced that it is now shipping new 22 TB HDDs targeting three key segments: WD Gold HDDs for IT/data center channel customers; WD Red Pro for network attached storage (NAS); and WD Purple Pro for smart video/surveillance. As highlighted in its What's Next Western Digital Event, these new drives are loaded with industry-firsts, including OptiNAND technology, energy-assisted PMR (ePMR), triple-stage actuator (TSA) and HelioSeal to deliver the industry's highest areal density at 2.2 TB per platter, delivering 22 TB CMR HDDs for its customers.

Western Digital started selling an 18 TB variant of its WD Gold line of "enterprise class" SATA hard drives (model: WD181KRYZ). The WD Gold series tops the company's SATA HDD lineup and its in the gray area between client and scalar enterprise segments, where the company sells its HGST Ultrastar HDDs. WD Gold drives are still rated for 24x7 operation, and can be safely used in large RAID arrays. The drives are confirmed to lack SMR and DM-SMR; and are confirmed to use CMR (conventional magnetic recording), which ensures predictable write speeds and random-write performance. The WD Gold WD181KRYZ features 7,200 RPM spindle speed, HelioSeal technology (the main disk chamber is sealed and filled with inert helium gas), and 2.5 million-hour MTBF. Performance numbers and cache size for the 18 TB model are unknown, but the 14 TB variant in this series offers up to 267 MB/s sequential transfers, and features a 512 MB DRAM write cache. The WD181KRYZ is listed on UK store SCAN for £520.

Western Digital is enabling small and medium-sized enterprises (SMEs) to easily transition to NVMe storage and dramatically improve application performance with a new addition to its portfolio of data center NVMe SSDs: the first enterprise-class NVMe SSD in the WD Gold family. Industry analyst firm IDC expects NVMe unit shipments to reach more than 79 percent of the market by 2023. With advancements in multi-core, multi-threaded CPUs, legacy storage technology has become a bottleneck to maximum application performance.

Shipping in early cQ2 2020, the new WD Gold NVMe SSDs will be available in four capacities to channel partners and end customers. The WD Gold NVMe SSD is designed to be the primary storage in servers delivering superior response times, higher throughput and greater scale than existing SATA devices for enterprise applications. WD Gold NVMe SSDs complement recently launched WD Gold HDDs by providing a high-performance storage tier for applications and data sets that requires low latency or high throughput.
