Seagate takes a new step in making hamr hard drives

Seagate has passed another milestone in hard drive manufacturing, creating the world's first functional 16TB HDD based on HAMR (Heat Assisted Magnetic Recording) technology, featured in the 3.5-inch industry standard and ready to go. customers in 2019.

Seagate already has a 16TB HAMR hard drive

The major innovation with HAMR is its compatibility with standard systems, as HAMR drives appear to be identical to standard PMR (Perpendicular Magnetic Recording) hard drives, which offer plug-and-play functionality on today's servers. In the eyes of customers, all they will see is faster HDDs, making the HDD HAMR easy to deploy and buy. While PMR-based 16TB hard drives are slated to launch in mid-late 2019, Seagate's plans for HAMR will actually begin in 2020, where their first 20TB hard drive will be released. In 2024, Seagate plans to release 48TB hard drives, showing the enormous potential of HAMR.

Heat-assisted magnetic recording is not a new concept, it uses a small laser to heat up a hard drive, so weaker magnets can be used to write to the surface of the unit, allowing data to be printed on a smaller area, increasing the capacity of a hard disk. Western Digital has proposed an alternative technology called MAMR (Microwave-Assisted Magnetic Recording), which uses the company's innovative "Torque Oscillator" to generate a magnetic field, which can enable the manufacture of ultrahigh-density hard drives. without any degradation in reliability.

After testing its new 16TB EXOS HAMR drives, Seagate further verified its impressive laboratory reliability test results, claiming that its drives far exceed industry reliability standards. Seagate says its lifetime data transfer capabilities exceed consumer standards by a factor of 20, which is no easy feat for a new HDD recording technology.
