As we have seen in other articles, two of the world's top companies have placed their strong bet on different technologies that aim to achieve the same goal. HAMR vs MAMR vs ePMR It is news where we are being imported from last year and the first HDDs have come into the business market with much criticism.
But this is not enough because of the high amount of data that large companies manage, so they require high energy units to cope with low energy costs and location. Showa Denko has found a solution and unveiled its new HAMR vessels.
Up to 80 TB with high performance and low utilization due to HAMR
Vessels are the basic unit of any modern HDD. The recording technology they use will have an impact on the two key factors and the third party in agreement, but it's very important. These items are standard per inch or mm2, speed in MB / s and thickness.
Based on technology HAMR The next-generation HDD, the Showa Denko (SDK) introduced its new plates with heat-assisted recording, using a very thin and magnetic film with a very small glass band size, increasing the area and size
The goal according to the company is to provide HDD up to 80 TB in just a few years because of these new, thin aluminum plates. Fe-Pt alloy.
Large quantities mean severe difficulties in reading and writing in the heads
The problem with HDD is that the spatial discrimination found on each plate means a huge jump in literacy rates. Writing in less space and more accuracy means that the so-called electrical interference between the tracks is much stronger and that the heads are less accurate when reading the data.
In addition, they have to do it at high temperatures during filming. The SDK says its vessels overcome all of these challenges and unlike what one might think, the size they will reach will be more than 5 times that of the current one, reaching almost 6 TB per centimeter.
This will lead to some HDD's that in the same containers as the existing drives will reach 80 TB capacity on average. This means that in a few years time it will double the number of HDD power upgrades much like the Seagate introduced by the end of 2019 with 20 TB and that will come, in a sense, later this year.
In terms of performance, the company did not specify the MB / s price to expect for these new vessels, merely confirming that they will be higher than what we currently have in the market.
