A person who is not very computer-savvy needs to store 130GB of photos. The key parameters are:

• an non-negligible probability that the company selling the storage will be existing, and the data accessible, for at least five years
• data should be considered safe once uploaded
• reasonable terms of service: google drive reserving the right to literally do anything they want with their user's data is not acceptable; the possibility that the CIA might look at those pictures is not considered a threat
• easy to use from Windows, preferably as a drive
• no nerve-wracking limitations ("cannot upload >10GB/day" or "files >500MB" etc.) that serve no purpose other than pushing the user to the next-higher price plan
• some upgrade plan: there's currently 10-30GB of new photos per year, with a tendency to increase, which might bust a 150GB limit next January
• ability to somehow sort the pictures: currently they are sorted into folders, but something alike (tags) would be just as good, if easy enough to apply
• of course, the pricing is important (although there's a reason this is the last bullet; reasonable data safety is considered more important)

Nice to have, but not necessary features would be:

• additional features related to photos (thumbnail generation, album sharing etc.)
• access from web and other platforms than Windows (smart phones)

Let me stress this again: The person in need of that is able to copy pictures from the camera to the computer, can copy files in the explorer, and uses a web email service. That's about it, there's almost no understanding of what happens under the hood.
