Discovery Glass 16TB Hard Drives: Western Digital CEO Michael Cordano revealed at a financial meeting last month. That his 16TB hard drive had passed all their internal tests and is now in the hands of companies.
They also released a new roadmap starting this year with 16 TB and 18 TB hard drives and a TB capacity of at least 20 in 2020.
Pricing has not yet been revealed, but if the product data center. Enterprise use cases are targeted, prices will undoubtedly reflect that. The 16TB hard drives run at $ 500 to $ 600. Which is 20% more per GB than a 2TB HDD?
Performance has not yet been determined but is currently 10-15% faster than high-capacity hard drives. WT was the first to use the new microwave-assisted magnetic recording (MAMR) technology.
MAMR allows manufacturers to increase the density of information stored on disk, which increases efficiency and speed.
Hard drives reflect 1 or 0 small metal hairs that can be magnetically flipped over. The reading/writing head, but those hairs have shrunk in size to increase the density of storage manufacturers. As they become smaller, they require more energy.
16TB Hard Drives using MAMR Technology Sampling
The head flips as it begins to generate more energy. The hair is more difficult to control and more bugs are found.
MAMR solves this problem by integrating the Spam Torque Oscillator into the reading / writing head, which gives more power to the hair.
Because they have high energy, they can be easily affected by different magnetic fields through the reading/writing element of the head.
However, Western Digital has revealed that they are researching a competitive solution called heat-assisted magnetic recording (HAMR). HAMR Seagate uses the recently announced 16TB hard drive.
It works on all principles like MAMR, but instead of using an electric field to stimulate the hair, it uses a small laser, which heats the plate from 400C to 700C.
Western Digital is surprised to hear that they have investigated this route, having previously declared the laser to be too expensive and the constant heat unreliable.
