Data storage density continues to prove Moore’s Law Posted: Sat, 17 Oct 2009 - 12:36 Tags: Terabits, Megabytes, Data Storage, Disk Crash, data, magnetic recording, disk drives, heads, disk

The Data Storage Institute has recently announced that it is embarking on its 10 Terabits per square inch program.  This technology is destined to further increase the storage capacity of disk drives to allow even greater amounts of data to be stored on ever smaller disk drives.

The Data Storage Institute has recently announced that it is embarking on its 10 Terabits per square inch program.  This technology is destined to further increase the storage capacity of disk drives to allow even greater amounts of data to be stored on ever smaller disk drives.

The Data Storage Institute was established in 1996, it is a national research and development institute in Singapore.

One of its core interests is high density magnetic recording and it is one of the world’s top 5 research centres.

These advances are all the more astounding when you compare early disk drives from 20 years ago, which held just a small number of Megabytes on large 14 inch aluminium disks. These early monsters were often the size of a washing machine in a commercial laundry and twice as noisy.

They had to be operated in an air conditioned environment because the heads and disks were not sealed. A piece of dust or a human hair could cause a devastating disk crash which could quickly destroy all the data by literally burning the recording surface from the disks.

  To achieve the capacity of 10 Terabits of storage, from those old machines, it would be necessary to have over 4000 of these machines spun up and running at the same time. A space requiring an air conditioned room so large that it would be possible to park around 1000 cars and the kind of electrical connection that could adequately supply a small town.

Moore stated his law to address the advance of data storage from the mid 1960s, when he predicted that data storage would double every 18 months. He is not far wrong when you consider this current announcement.
