Large File Systems - Enough inodes?

[Kenneth Jacker <khj@be.cs.appstate.edu>]

I am buying two new SATA hard drives:   1TB and  2TB.

I'd like to use the 2TB unit for backups (typical Linux directories and
files) ... with just a single file system (ext4 most likely).

Will 'mkfs' create "enough" inodes?  Or, would it be better to, say,
split the 2TB into four 500GB file systems.  Or, some other approach?

Thanks for your ideas!
