Bacterial DVD Holds 50TB

CAMags writes to tell us that a Harvard Professor is claiming to have developed a new variant of a protein called bacteriorhodopsin (bR) that, when layered on a DVD, can store up to 50TB of data. From the article: "The light-activated protein is found in the membrane of a salt marsh microbe Halobacterium salinarum and is also known as bacteriorhodopsin (bR). It captures and stores sunlight to convert it to chemical energy. When light shines on bR, it is converted to a series of intermediate molecules each with a unique shape and color before returning to its 'ground state.'"

  1. I bet these will have the same problem as CD-RWs by basil+montreal · · Score: 5, Insightful

    Any time you use an organic compound for storage, you need to worry about the organic half life of the device. Writable optical media uses organic dye, and will only last several years in storage. I didn't see anything in the article that indicated this technology would be any better...

  2. 50 TB? by eebra82 · · Score: 5, Insightful

    I wonder why these numbers are so greatly exaggerated. Why can't scientists leave the theoretical figures behind and talk about realistic numbers?

    Anyway, once we actually reach data storage of that magnitude on a disk, we'll have to face the problem of seek time and transfers. It would be ridiculous to post so much data on a disk, so when this technology is mature, I'm sure disks will be obsolete.

    Scientists should spend more time on figuring out how to leave the world of milliseconds and approach the nanoseconds. Remember, the only thing that's running on milliseconds in a computer is based on platters. I'd rather move on from that and get my 50 TB later.
