Seagate Technology, a world leader in sustainable mass-data storage solutions, today announced a milestone that marks a new era in the storage industry. The company launched the Mozaic 3+ hard drive platform—which incorporates Seagate's trailblazing implementation of Heat-Assisted Magnetic Recording (HAMR) technology. The launch heralds unparalleled areal densities of 3 TB+ per platter—and a roadmap that will achieve 4 TB+ and 5 TB+ per platter in the coming years.

The Mozaic 3+ platform powers Seagate's flagship Exos product family, with newly announced, industry-leading capacity points of 30 TB and beyond. Exos 30 TB+ products are shipping in volume this quarter to hyperscale cloud customers. Seagate's areal density innovation—which increases the number of bits that can be stored on a platter—addresses common industry pain points. Mozaic 3+ enables customers to store more data in the same floor space than ever before. Upgrading from a 16 TB conventional perpendicular magnetic recording (PMR) drive (the average capacity in large-scale data centers) to an Exos 30 TB Mozaic 3+ technology drive effectively doubles capacity in the same footprint.

Seagate is celebrating the debut shipment of very sophisticated storage solutions to a preferred client (dealing in the cloud data center sector). These 30+ terabyte hard drives are based on heat-assisted magnetic recording (HAMR) technology - the American data storage company is setting up its next generation Corvault range with the thermal magnetic recording methodology. The first shipment of HAMR-based drives is reported to consist of final qualification samples, but Seagate is anticipating that fully verified equipment - after trial customers give this new product lineup a thumbs-up - will be generating revenue in the coming weeks.

According to a transcript of a recent Seagate financial meeting conference call, CEO Dave Mosley mentioned a dip in business as well as a costly legal settlement, but expects company fortunes to rise due to client uptake of breakthrough storage technologies: "Beyond this cycle, we remain excited about the long-term opportunities presented by the secular growth of data and the relevance of mass capacity storage as new data-centric applications emerge and more workloads migrate to the cloud. We continue to make strong progress on our industry-leading technology road map, including launching HAMR-based products this quarter, which we believe put us in outstanding longer-term position."

Seagate has been hyping their new HDD density-improvement technology, HAMR, for some time now. The basis of HAMR (Heat-Assisted Magnetic Recording) in Seagate's ypcoiming HDDs is to increase platter density without having to resort to other solutions so as to increase HDD capacity (increased number of platters, increased footprint, etc). The company says that internal tests of 16 TB HAMR-based HDDs are going well, with expected market release to partners by 2019.

HAMR does keep up with compatibility for enterprise customers, being a drop-in upgrade for other HDD-based storage solutions - they're just higher capacity, higher-performance solutions that don't need any special treatment from deployers. The plan is to release 20 TB solutions by 2020, and a staggering 48 TB in the standard 3.5" form-factor by 2024. Seagate further states that HAMR-based drives far exceed industry-required reliability parameters, so the company is bullish on the attention its technology will garner once available to customers in general. The HAMR tech will be deployed firstly on the company's
