At some point, it has to be cheaper and logistically simpler to transfer ownership and not transport the bits. Or the old fallback:

Never underestimate the bandwidth of a station wagon full of tapes hurtling down the highway. - Andrew S. Tanenbaum

Absolutely we don't try to hide that information you can try out our file transfer calculator here https://www.masv.io/file-transfer-calculator/ - This compares MASV to shipping hard drives and uses real rates from the fedex api. The way I like to think of it is it's much more convenient to transfer online instead of shipping hard drives as there is just less to deal with and it's harder to scale. So if MASV is faster or not much longer then shipping a drive or hand delivering then it's time you can spend on taking on more projects.

You got it. In general you can send as much or as little as you need with MASV because it's pay-as-you-go which means you don't have to manage fixed storage and it scales up and down with your work. If you don't use it the next month it costs nothing.

Google Drive allows files up to 5TB https://support.google.com/drive/answer/37603?hl=en but does not give any guarantee you will not breach some magical limits set.

I guess MASV is transparent about file sizes (no limit) and bandwidth is the resource you pay for, so there is transparency on the SLA.
