Likely a lot less than 1 mile. LTO5 stores approximately 3 TB with Compression. (1.5 Native). It is 846m long. Let us assume you have 7597MB of emails in your gmail inbox. That's about .48% of the capacity of a Uncompressed tape. So that's a smidge over 4m. And if google compresses their data -- then you're potentially looking about 2m.
