Western Digital expands video storage range


Storage vendor Western Digital has announced two new members of its Purple range of storage devices designed for video.

The two new products are the 18TB Purple hard drive intended for use in DVRs, NVRs and analytics appliances, and the 1TB Purple SC QD101 microSD card for AI-enabled cameras.

WD Purple drives are designed to help reduce frame loss and pixelation, improve overall video playback and enhance streaming for 24x7 workloads, the company said.

For example, the AllFrame technology in WD Purple hard drives uses caching and streaming management techniques to help prevent data loss, while the Device Analytics software assists with the early detection and remediation of drive issues.

But it's not just a matter of capturing video. The growing use of deep learning and analytics means data has to be ingested, backed up, and held in long-term storage. WD Purple drives the company's software are said to improve performance, reliability, durability and overall better operational efficiency and TCO for customers.

The WD Purple 18TB hard drive provides 28% more capacity than its predecessor. Like all WD Purple drives of at least 8TB capacity it incorporates the AllFrame technology to allow the recording of up to 64 HD cameras, plus another 32 streams for deep learning analytics.

The WD Purple SC QD101 1TB microSD card is designed to provide primary or backup storage for AI-enabled cameras, surveillance cameras and edge devices, with an endurance with up to 500 P/E (program/erase) cycles and an operating temperature range of -25C to 85C.

"Working side-by-side with our customers and ecosystem partners gives us unique insights and focus on delivering solutions that are optimised for the most advanced security video workloads," said Western Digital vice president of client computing and smart video business Eric Spanneut.

"AI is driving the need for more enhanced capabilities in drives to keep up with performance demands, especially as video resolution and the number of incoming streams increase.

"We are in a unique position as the combination of our software and expanding drive portfolio makes our solutions ideal for deployment into a multitude of smart video applications."

The WD Purple 18TB HDD will be available in October 2020, and the WD Purple SC QD101 1TB microSD card is scheduled for November 2020 availability.

Now’s the Time for 400G Migration

The optical fibre community is anxiously awaiting the benefits that 400G capacity per wavelength will bring to existing and future fibre optic networks.

Nearly every business wants to leverage the latest in digital offerings to remain competitive in their respective markets and to provide support for fast and ever-increasing demands for data capacity. 400G is the answer.

Initial challenges are associated with supporting such project and upgrades to fulfil the promise of higher-capacity transport.

The foundation of optical networking infrastructure includes coherent optical transceivers and digital signal processing (DSP), mux/demux, ROADM, and optical amplifiers, all of which must be able to support 400G capacity.

With today’s proprietary power-hungry and high cost transceivers and DSP, how is migration to 400G networks going to be a viable option?

PacketLight's next-generation standardised solutions may be the answer. Click below to read the full article.
