Um, how much hardware is this thing going to require?
Exhibit A: Win Vista
From what I have read, I don't think it takes much hardware to support ZFS; if anything, it is probably less complex than the current melange of layers of volume managers and filesystems. Apparently it's already been ported directly to FreeBSD, and I believe that you can also run it in some fashion under Fuse on Linux.
What about Windows Vista? How does that relate to a Sun-developed filesystem? (If you’re referencing WinFS, it got axed.)
ZFS will actually improve system performance when doing data-intensive tasks, like loading iPhoto.
You don’t know what you are talking about.
Win Vista is hardware?
