Yes. For speed purposes. RAID read speeds vastly outstrip drives on their own. I can't do most of what I do (working with large datasets) without hardware RAID.
I have an 8TB server that also uses an additional 1.5TB of drive storage for system and temporary data. I back everything up to a grid storage system based on tahoe; the other servers running in my house together combine to form enough space to back up my larger server--even with the expansion required to form a 3-of-5 method set of erasure code blocks per-file.
The tahoe grid is probably more reliable, combined, than the big server. If some of the machines die, it's really not a big deal: tahoe makes sure that the overall grid is fault-tolerant. Their favourite quip: "tahoe, the axe-resistant filesystem."
I refuse to use online backup systems because my datasets are so huge. Really the only protection I'll get anyway is if I back this stuff up into spare drives and dump them into a safety deposit box somewhere.
