Seagate’s new architecture, called Mozaic, unifies data storage, processing and transfer under a single platform. It provides better optimization of AI applications and management of the voluminous data that many companies work with. At the same time, this architecture delivers entirely new write and read technologies for hard drives that further improve overall system performance and reliability.

Seagate currently has five different drives in its Exos series, which is targeted for server deployments. Some of the models have significant unique features, for example the Seagate Exos 2X18 brings the innovation of dual read heads, effectively doubling speed, increasing random IOPS and improving sequential read/write performance. The table below lists the key specifications of all current models in the Seagate Exos series.

Seagate offers enterprise SSDs under its Nytro line. This line includes four series of different capacities and formats, so you can choose a drive for every build.
SSDs, or solid state drives, are a popular type of storage due to their greater mechanical durability and read/write speeds. These features make it virtually impossible to encounter any other kind of storage in AI training solutions, for example.

The Seagate Mozaic 3+ architecture, first used on the new Exos datacenter drives, brings key innovations to the hard drive market. The new concept of how data is written to and read from a magnetic platter works with innovative technology HAMRwhich allows data to be stored at much higher densities. Drives based on this architecture have significantly higher data density, as their magnetic platters are able to store up to 3 times more data in the same area thanks to a special structure. Of course, other components have also been modified to maximise the drive’s potential. That’s why Mozaic drives use a unique write and read method, have improved read heads and are driven by a new controller with only 12nm lithography for improved efficiency.
HAMR stands for “Heat Assisted Magnetic Recording”, or heat assisted magnetic recording. This technology from Seagate completely changes the fundamental principles of hard drive data storage and reading, as it now uses a laser diode instead of the conventional electromagnetic head found in conventional hard drives to heat the magnetic platter of the drive and then precisely reverse the polarity of one bit in a block. The surface of the magnetic platter is heated and cooled within nanoseconds, and even in long-term testing, this process did not affect the life of the disk. If we also consider that with this technology we are now able to store up to 3 TB of data on a single platter, we are able to make drives with density and speed that can fundamentally improve the performance of disk arrays used for corporate data, performance or AI training.
Platinum gridTo create a data storage layer with higher magnetic coercivity, Seagate has developed a special iron-platinum structure in which the location of each atom plays an important role.
Plazmonic writerA key feature of this writing mechanism is its ability to precisely heat the grid structure of the plate above 400°c, which then cools in less than two nanoseconds.
Spintronic readerThe Gen 7 spintronic reader detects subtle changes in magnetization and provides very accurate and fast data reading at ultra-high areal densities of the lattice structure.
12nm controllerDesigned for data mobility and data integrity, the 12nm integrated controller meets the growing data demands of digital media, enterprise software and cloud systems.
Most data centres will soon start to face a fairly modern problem – users are starting to generate more data than application servers can process and store in the long term; according to statistics, by 2024, users will produce 30 zettabytes of data, while data centres will generate about 2 zettabytes of new storage. However, with the advent of AI and the demand for unique training data, it doesn’t make sense to delete this information and therefore servers need to be prepared for this data. Since datacenter space is quite limited, it is thus very advantageous to increase the data capacity of the disks themselves. However, even this has its limits – but Mozaic 3+ takes these even further and is able to provide data densities of up to 3 TB per disk platter. This makes high-capacity HDDs for data centres more affordable, faster and more reliable than ever before, and can meet the modern demand for data and storage.
