If there was a 5TB drive, nobody would be able to back it up. That is, those that even think of such things. Most computer users would just keep piling junk on the drive and never even thinking they need to back up or do any sort of Spring cleaning because there is so much space. One day, the drive will fail and they will loose 20 years of data. You think you were mad when your 20 gig drive died? When the 5TB drives come out, you better put the actuaries on notice, because suicide rates will spike. :-)
