Last year's proposalNew Mozaic 3+ platform design, boasting that it uses Heat-Assisted Magnetic Recording (HAMR) technology, combined with the principle of laser heating, to record digital data on magnetic tracks thinner than a hair on the disk, increasing the storage capacity of a single disk to more than 3TB and allowing hard drive capacity to be increased to 30TB. In addition to supplying large quantities of its Exos X flagship series storage products to hyperscale cloud customers, Seagate also earlier launched the Exos X series to meet the needs of the general consumer market.Exos M series hard drives, with a capacity of up to 32TB.
Although it was a step behind Western Digital's WD brand, which had already launched a 32TB hard drive, Western Digital's hard drives utilize the relatively mature ePMR (Energy-assisted PMR) technology and utilize up to 10 platters. Therefore, increasing storage capacity within a given space by increasing the number of platters is challenging. Seagate's Mozaic 3+ platform design clearly has greater room for growth.
Seagate previously stated that while the Mozaic 3+ platform design will initially be used for ultra-large-scale data center storage needs, it will also be rolled out to consumer products in the future based on market demand. This includes considering introducing this technology into 2.5-inch hard drive products that have not seen technological updates for a long time, thereby increasing the storage density of small hard drive products.
However, Seagate emphasized that the decision depends primarily on market demand. After all, current storage needs for small devices are mostly concentrated in SSDs and other flash memory storage products. Therefore, whether the Mozaic 3+ platform design will be implemented in 2.5-inch hard drive products will ultimately depend on actual application scenarios.
The Exos M series hard drives, currently available with a capacity of 32TB, are consumer-grade storage products designed and built by Seagate based on the Mozaic 3+ platform, which can attract more users who need to store large amounts of data.
