One of the big problems facing whole-genome research efforts these days is archiving. A single experiment can generate a terabyte or more of data, and while it’s all conveniently stored on hard drives in the short term, that’s a poor medium for handing down the scientific heritage of mankind. The problem is twofold: digital data storage changes constantly, and many formats that were sold as “archival” have since turned out to be alarmingly perishable.
