Seagate HAMR: Welcome to the future of high capacity discs


Seagate, the world’s leading storage company, is proud to announce that by the end of this year, Seagate Key customers will receive the first hard drives using magnetic-assisted recording technology, HAMR (for its acronym in English).

HAMR units are as simple to use as any traditional unit. With these shipments, it will be shown that the units are: Plug & Play, reliable; And they will be ready to be marketed in 2019!

HAMR is a technology designed for the upcoming information age; Storable on a hard drive. Each disk has a new type of coating that allows data bits to become smaller and more compact, while remaining magnetically stable. A small laser diode connected to each recording head leaves a small spot on the disc, allowing the recording head to make a turn in the magnetic polarity of each stable bit, for the writing of the data.

Why the insistence of having an ever-increasing data density?

It is said that for 2025, the creation of data around the world will grow to 163 zettabytes (ZB). HAMR represents the technological evolution capable of increasing the density of the data that the main suppliers capture as a benchmark of technology in the storage industry, according to the Advanced storage technology Consortium (ASTC).

Seagate has been for many years the leader in investing in the future of hard drive technology and addressing the weaknesses of data centers.

HAMR: The leader in data density

HAMR is about to deliver 20TB units or more in 2019 and continue with an annual growth rate of 30% per data density, to finally reach 40TB or more at 2023. A unique and crucial growth rate of HAMR that guarantees the TCO (Total cost of ownership) advantage that data centers require.

HAMR, along with the technologies SMR (magnetic staggered recording) and TDMR (two-dimensional magnetic recording), offers the industry the best cost for TB and allows customers and products of companies to maximize their capacity and performance in each Market.

HAMR Technology is now ready

Ten years ago, the study and development of HAMR’s head design technology was complex. After years of research and comparing the inherited technology, Seagate’s R&D team discovered that the solution was to add a laser to each head, so the HAMR architecture was built: the technology that offers the highest density of Data

To date, Seagate has built and tested more than 40.000 HAMR units. These discs have demonstrated the ability to reliably transfer more than 2PB data to a head; This is equivalent to 35 PB of data transferred in a five-year lifespan in a 12 TB drive, much more than any real-world expectation.

The future of high-capacity disks is solved. Seagate HAMR is already a reality.
