I've used AWS snowballs fairly frequently and it is definitely a specialty product. For our use case it was genome sequencing. Each individual genome was a terabyte or so depending on what types of data we sent. We can crank out a few hundred genomes per week at full production so when our collaborators need to receive their data they usually neither have the capacity in bandwidth or storage for cohort of thousands. So it gets shipped to AWS. We've made improvements to get more direct connections to cloud services so we don't use them anymore but for awhile we were filling a snowball and shipping it every week or two. We also used the Google Transfer Appliance once or twice (480tb) to transfer projects all at once instead of piecemeal.
