Seagate reach 1TB per square inch hard drives

Seagate breaks record for hard drive storage capacity.

Hard drive manufacturing giant Seagate has revealed that it has managed to manufacture a hard drive that has a storage density of 1 terabit (1 trillion bits) per square inch using heat assisted magnetic recording technology (HAMR).

This is the next generation of data recording. It heats an area on the drive so that it can be magnetically flipped. That bypasses the superparamagnetic effect whereby small magnetic particles choose to unexpectedly change state, which turns data into mush.

It could replace current technology, perpendicular magnetic recording (PMR), as it provides the ability for a 3.5-inch hard drive to store an unbelievable 60TB.

Seagate was not shy about contextulising their achievement, pointing out that in an inch of their hard drive space, at this new record’s storage capacity, there are more bits than there are stars in the Milky Way.

The current ceiling capacity for a 3.5-inch PMR drive is around 3TB and 750gb for a 2.5-inch drive.

When HAMR drives are introduced to the market, they are likely to double that with the possibility to increase it further at a rate not known before.

Despite this, it could be a long time before hardware enthusiasts get their hands on a HAMR drive, as all Seagate are saying is that it will be some time “later this decade”.

“The growth of social media, search engines, cloud computing, rich media and other data-hungry applications continues to stoke demand for ever greater storage capacity,” said Mark Re, senior vice president of heads and media research and development at Seagate.

“Hard disk drive innovations like HAMR will be a key enabler of the development of even more data-intense applications in the future, extending the ways businesses and consumers worldwide use, manage and store digital content.”

The first hard drive to be commercially available on a widespread basis was the ST-506 that was 5.25 inches in size, which made it small enough to be put into a microcomputer. However, the 5MB drive cost a whopping $1,500.ADNFCR-1220-ID-801323508-ADNFCR
