It's always nice to know that people can store their data for so long. In my research lab, we still only use separate external HDD drives due to budget reasons. Last year 4 (over 8) drives failed and we lost the data. I guess we mainly work with public data so it is not a big deal. But, it is a dream of mine to research without such worries. I do keep backups for my stuff though, but only me in my lab.
