Acutally, Box will offer some protection. Box will sign a Business Associate Agreement (BAA), asserting that they provide HIPAA-complaint security for stored data.
At present, Dropbox does not offer such an agreement.
Not the same thing as compensating you properly for losing your data or making you suffer downtime for an unreasonable period though and HIPPA is not much good unless you work in the medical industry.
How do you even begin to quantify the contents of somebodies personal Dropbox folder full of junk ?
You do not, you cap value at a certain point for individuals or businesses based on the number of gigs they have.
