Yes:
- capacity
- speed
- technological lifespan (newer, so will probably be around after dlt is
gone)
- durability (drive match data rate so drives and media have a longer
lifespan 

We paid about US $2300 for an external hp960 a few months ago.  You may
need fewer lto tapes (because they hold more data), so maybe this will
offset the higher cost of the drive.  I load 700GB+ on my lto4 tapes, so
3 may be all you need to do a full backup.  

I use bacula to backup about 14 servers (win/lin/osx) nightly.  I run 20
jobs, concurrently backing up each server to tape and raid.  As one job
finishes, another waiting job starts.  Takes about 2 to 3 hours.  

I backed up a 3TB raid in a few hours this hardware with bacula.  Maybe
the time saved doing backups, and the faster restore performance (faster
uptime) can be used to help justify the higher cost...  

FWIW.
