In the mid 90ies there were 9GB hard drives availabe, which is roughly the same amount of data that fits on 14 CDs. Today we have 14TB sized HDDs, so an equivalent optical disk should be able to store 1TB of data. However today a private person easily has more than one device plus several external HDDs to store his or her data. So I guess it would not be too greedy to demand permanent media with a capacity of 10TB. Comparing with CDs the price could be 2USD. So in this comparison I honestly find a 6TB tape for 200USD incredibly expensive.
