Moving 237.22 TB in 7 days requires ~3.14 Gbps of bandwidth, assuming that the clock starts ticking the moment that he actually starts moving data. In practice, the requirements would be even higher (subtracting out the time between notice being sent and read, plus time to actually set up alternative storage). Does Google even provide that level of read throughput to Google Drive customers?

I have to repeat the question: do you genuinely believe this data is going to be inevitably deleted, or maybe do you think that the threat will work and the guy will get his stuff downloaded somehow?

Do you similarly think it's perfectly ok for a loanshark to "threaten" to smash the customer's knees if they don't pay up in 7 days? Because obviously they wouldn't really do that?
