Right. Video editing or simple video storage (I still plan one day to put all my DVDs and BR on disk) and you're ready to fill one more order of magnitude storage.

Also, I am currently able to store all my home data in a RAID 1 6TB system. Admittedly, a lot of work stuff is in the office storage system (much larger), but my point is: you'll still be using RAID even though just for mirroring.

Here's another bet: in 5 years, we'll be on SSD-only sotrage in homes - again unless you store a lot og 4K (8K) video content by then.
