    Seagate: hard drives of more than 50 TB in 2026 !

    Seagate: hard drives of more than 50 TB in 2026 !

    It is not because the SSD is clearly on the rise that it will supplant our good old record discs. Seagate will continue to develop technologies to continue to increase their capacity.


    The bar of 50 TB should be crossed in 2026 according to Seagate. The storage solutions manufacturer recently made some phone presentations in which it unveiled a roadmap indicating the next steps in developing hard drives. At the end of next year, 20TB solutions should be available in the consumer market, a little earlier for the pros. In 2023, the 30 TB will be crossed then, 3 years later, that of 50 TB.

    "Today, Seagate is the only company capable of massively producing 16 TB disks, which has become an industry standard," said brand CEO Dr. Dave Mosley when announcing the financial results. "We are currently preparing 18TB solutions that will arrive at our customers in the first half of next year."

    To reach 50 TB, Seagate relies on the HAMR technology (Heat Assisted Magnetic Recording) which, for simplicity, uses a writing head which is equipped with a small device able to heat a little more than reason the surface recording of data. Thus, it allows to magnetically write the information, in smaller portions of the board and that can not be reached otherwise.

    Before mass HAMR, there is the volume SMR

    For now, Seagate continues to use conventional read / write methods but, from the 20 TB model, the manufacturer plans to change its tune. It would be a question of using the SMR method (Shingled Magnetic Recording) which aims to increase the density of storage on the supports, tightening the reading tracks so that they overlap slightly and form a kind of aliasing. Everything is played on a microscopic scale of course and we explain the SMR here in broad strokes.

    The fact remains that although the SSD is becoming a must for the installation of operating systems, heavy applications or making many calls discs, nothing replaces a good old HDD plateau. It is still he who keeps the palm of the best price / capacity ratio (not to mention the longevity) to mass store documents, uncompressed music or 4K films that weigh several tens of GB.
