You don't say what your storage requirements are and what your
performance requirements are.
You might consider a small SSD and a pair of N-terabyte hard
disks in RAID1. Put performance-critical things on the SSD, and
keep a backup on the hard disks, along with
non-performance-critical data.
I've assessed my desktop data usage, and I think I can get away
with a 120G SSD and a single 1 TB spinning disk, using rsnapshot
to copy the SSD a few times a day.
