Hyperscale data centers lead adoption of the
new Mozaic 3+ platform that delivers unprecedented areal density of
3TB+ per platter
Seagate® Technology Holdings plc (NASDAQ: STX), 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 3TB+ per platter—and a roadmap that
will achieve 4TB+ and 5TB+ 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
30TB and beyond. Exos 30TB+ 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 16TB conventional
perpendicular magnetic recording (PMR) drive (the average capacity
in large-scale data centers) to an Exos 30TB Mozaic 3+ technology
drive effectively doubles capacity in the same footprint.
The platform uses roughly the same material components as PMR
hard drives while dramatically increasing capacity, allowing data
centers to significantly lower storage acquisition and operational
costs—including a 40% improvement in per terabyte power
consumption. Mozaic 3+ can also help customers achieve
sustainability goals—a top priority for large-scale data centers—by
offering a 55% reduction in embodied carbon per terabyte (when
comparing a 30TB Mozaic 3+ drive with a traditional 16TB PMR
drive).
Seagate is experiencing strong demand from data center customers
that are expected to complete qualification of Mozaic 3+ and move
into volume ramp by end of this quarter. A leading cloud service
provider is focused on ramping of Seagate-provided drives to Mozaic
3+, reflecting their confidence in the technology.
“Seagate is the world’s only hard drive manufacturer with the
areal density capability to get to 3TB per platter and with 5TB on
the horizon,” said Dave Mosley, Seagate’s CEO. “As AI use cases put
a premium on raw data sets, more companies are going to need to
store all the data they can. To accommodate the resulting masses of
data, areal density matters more than ever.”
“The Mozaic 3+ platform represents more than just HAMR
technology,” Mosley noted. “It comprises several industry-first
innovations that we’ve integrated to help us scale areal
density.”
Here are a few highlights:
1. Superlattice Platinum-Alloy Media. Fundamental
physics of higher-density recording requires smaller media grain
size at nanoscale. The challenge here is that smaller grains are
more unstable. Legacy alloys do not provide sufficient magnetic
stability for effective and reliable storage. In Mozaic 3+ hard
drives, the media alloy uses a pioneering iron-platinum
superlattice structure, which significantly increases the magnetic
coercivity of disk media. This allows for precise data writing and
unprecedented bit stability.
2. Plasmonic Writer. Since the media are made
magnetically “harder” to prevent instability, the design requires a
revolutionary writer—a marvel of miniaturization and precision
engineering that is Seagate’s unique implementation of HAMR.
Anchoring this technology is a nanophotonic laser, which produces
an infinitesimal heat spot on the media surface to reliably write
the data.
Seagate plans to vertically integrate the nanophotonic laser
into the plasmonic writer sub-system. “Developing this unique laser
technology in-house for Mozaic 3+ will ensure even greater
efficiency and yield to support rapid scaling of volume
production,” Mosley said.
3. Gen 7 Spintronic Reader. Smaller grains of written
data are only useful if they can be read. Integrated along with the
sub-components of the plasmonic writer, the reader also needed to
evolve. Incorporating quantum technology, Mozaic 3+ includes one of
the world's smallest and most sensitive magnetic field reading
sensors.
4. 12nm Integrated Controller. Efficiently orchestrating
all this technology called for an integrated controller, a
system-on-a-chip, developed entirely in house. This sophisticated
application-specific integrated circuit delivers up to 3 times the
performance compared to prior solutions.
“Hard drive areal density improvements are critical for
economically and efficiently expanding the installed base of hard
drive-based mass storage, especially in data centers,” said John
Rydning, Research Vice President, IDC Global DataSphere. “Seagate’s
innovative areal density breakthrough is timely and will enable it
to deliver increasingly higher capacity hard drive products for
many years.”
In addition to data centers, Mozaic 3+ storage technology will
enable a wide range of use cases, ranging from enterprise, to edge,
NAS, and video and imaging applications (VIA) markets.
