  • In the cart leading the horse when its come to long-term digital storage? Few would desagree that there have been a tremendous shift towards writing our personal histories as digital data. The convenience of digital photos has lured people away from film, just an email has supplanted letters. Unfortunatelly, we have yet to demostrate that we can reliably preserve digital data for more than a few years. Will future generations be able to to browse the sentimental and historical artifacts we leave them the way we might flip through our grandparents' photo album? Clearly, the long-term preservtion of data requires a storage system than can evolve over time, while remaining cheap enough to allow the retention of anything that might be important. To fill this need, we have developed Pergamum, a distributed network of energy-efficient, hard drive-based storage appliances. Each of our devices, which we call a Pergamum tome, offers the low-latency access times of disks while being cheaper to buy an operate than either disk-or-tape-based systems.
