Bug Protein USB Flash drives reaches 50 terabyte (TB)

A sample USB drive / Flash drive size of 50 terabytes (TB) worth of data could will be in the market using bug protein memory to store data in less than one and half years. Professor V Renugopalakrishnan of the Harvard Medical School in Boston’s initial thought was to start out by coating DVDs with a layer of protein so that one day solid state memory could grasp so much information that the storing data on conventional computer hard drive will be outdated.

 Bug Protein USB Flash drives reaches 50 terabyte (TB)

Bug protein memory USB flash drive

Ultimately it will remove the need for hard drive memory completely. This is the future of flash memory. High-capacity storage devices like the new protein-based DVDs will be crucial to the defense, medical and entertainment industries. Transfer of information such as satellite images, imaging scans and movies will be traded in with terabytes of information. Magnetic storage technology will not serve the persuasive demand of storing data.

New protein-based DVD will have advantages over recent optical storage devices (like the Blue-ray). It will be able to store no less than 20 times more than the Blue-ray and sooner or later even up to 50,000 gigabytes (about 50 terabytes) of information. The first protein-based information storage structure to store terabytes of information is made of Membrane proteins. The star at the centre of the high-capacity DVD is nothing but a light-activated protein situated in the membrane of a salt marsh microbe Halobacterium salinarum. This protein is named as bacterio rhodopsin (bR), captures and stores sunlight to convert it to chemical energy.

Sunlight on bR converts a series of intermediate molecules each with a distinctive shape and color before returning to its ‘ground state’ (as zero). It is only for some hours or at most a day that the intermediates generally last. But modified DNA that produces bR protein is to create an intermediate that lasts for more than several years, which is a building block to store data for a binary system. Any of the intermediates can be ‘one’ and ground state surely is the ‘zero’. BR protein is engineered to make its intermediates more stable and durable at the high temperatures generated by storing terabytes of data.

The opposite site of the coin is modern technology flash drive like this  is so portable that wrong hands will be easily broadcast the large amounts of information with this new technology flash drives or pen drives. Fortunately or unfortunately science can be used or abused. Data can be stolen very quickly by this flashdrives. One has to have some safeguards or protection there. In conclusion with NEC in Japan, Renugopalakrishnan’s team has estimated a USB flash drive will be in the market in 12 months and a DVD in 18 to 24 months. The work has been funded by a range of US military, government, academic institutions and commercial companies, as well as the European Union.
