Unless you never plan on taking your tapes out of the library or have some VERY fast hardware, 35TB/tape doesn't do much except send a lot of empty tape off-site.
35TB is 35,000,000 MB. At 100MB/sec, that 350,000 seconds or a bit over 97 hours. In other words, you'd be writing for 4 straight days averaging 100MB/sec to fill a tape. Assuming you only write to a tape during a 12-hour backup window, 7/8 of your tape will be unused.
I'm personally waiting for an environment here where I can sustain writing to all of my tape drives at 100MB/sec. I can't drive all of my LTO-3 drives at full speed. Having drives that demand a lot more than that just contributes to a lot more stop/start.
