Since it's out why isn't there a price ??? Also 1TB max is this software restriction or there isn't just enough space for fatter HDD ?

The limitation is only physical size by now. So as far as I'm aware the current biggest SSD's/SSHD/HD's. Just noticed samsung is releasing 16TB 2,5 SSD's. I wonder how many people you have to kill for those. http://arstechnica.com/gadgets/2015/08/samsung-unveils-2-5-inch-16tb-ssd-the-worlds-largest-hard-drive/
