Seagate Mozaic 3+: HDDs with HAMR technology offer more than 30 TB of storage space

To date, classic hard drives offer the most storage capacity Up to 24 terabytes. However, this upper limit is now falling as Seagate has made an important breakthrough. The storage maker recently launched the new Exos hard drive that offers more than 30 terabytes of capacity. This is made possible by Implementation of HAMR, which extends the areal density to more than 3 terabytes per disk. In the next few years, 4 to 5 terabytes of capacity per disk can be achieved.

HAMR HDDs should be more efficient

According to Seagate, here comes almost the same The material is the material Used like a conventional PMR hard drive. However, storage capacity increases significantly, meaning fewer HDDs are needed in data centers. Ultimately, they should benefit from it Acquisition and operating costs Advantages – especially because power consumption per terabyte is up to 40 percent lower.

The technology is impressive

However, due to the higher surface density, smaller media grains are required, which are more unstable. Classic alloys would not be sufficient to ensure magnetic stability and thus reliable data storage. This is why Mozaic 3+ HDD is used Superlattice platinum alloy media with higher magnetic coercivity.

Since this makes the media “solid”, a new write head is also required So here comes one Nanophotonic lasers Used to create a small heat spot on the media surface. There is also a more advanced reading functionality that uses quantum technology. Furthermore, there should be a Spintronic Reader Gen 7 can be used, which is a particularly small and sensitive magnetic field reading sensor.
