HDD capacity has finally reached the 30TB mark, and Seagate announces the HDD 'Exos Mozaic 3+' that uses HAMR technology that significantly increases recording density.
Seagate, an American storage device manufacturer, announced on January 17, 2024 that it will launch the Mozaic 3+ HDD platform for data centers, which will be the first in history to achieve a capacity of over 30 TB, by March 2024. did.

'Mozaic 3+' announced by Seagate is an HDD platform that achieves an areal density of 3 TB per platter (magnetic disk) using ' thermally assisted magnetic recording (HAMR) ', and is part of the company's main product 'Exos' series, which has a capacity of 30 TB. The above 'Exos Mozaic 3+' will be released on the market in the first quarter of 2024.
'We are the only HDD manufacturer in the world with areal density capability of 3TB per platter, and we are also looking at 5TB,' Seagate CEO Dave Moseley said in a statement. Specifically, in addition to plans to release 'Mozaic 4+' with a capacity of over 40 TB by 2026, 'Mozaic 5+' with a capacity of over 50 TB will also be released as early as 2028.
The key to achieving both capacity and stability in magnetic media is coercive
The recently announced Mozaic 3+ has succeeded in dramatically improving areal density using HAMR, which heats the storage area for a short time and writes while rapidly reducing the coercive force. ' has double the capacity per footprint compared to the 16TB perpendicular magnetic recording (PMR) drives used in conventional large-scale data centers.
Mozaic 3+ also features ' superlattice platinum alloy media ' that has an iron-platinum superlattice structure that improves coercive force and achieves high bit stability, and a nanophotonic laser that creates an extremely small heat spot in the storage area. ' Plasmonic Writer ,' which enables reliable writing by generating data, and ' 7th Generation Spintronic Reader ,' which is equipped with the world's smallest and most sensitive magnetic field reading sensor. By integrating these technologies, It incorporates technologies such as a 12nm controller that delivers up to three times the performance.
These high-density technologies allow Mozaic 3+ to significantly increase capacity while using nearly the same materials as traditional HDDs, consuming 40% less power per terabyte in data centers than traditional 16TB PMR drives. %, and the amount of carbon per terabyte will be reduced by 55%.
'As AI use cases focus on raw data sets, more and more companies will need to retain as much data as possible,' said Moseley. Areal density is more important than ever.”
