Yeah, I should add that I wanted persistence too.  I went through a
whole stack (well, 5-6 or so) fibre channel drives from various
vendors and attempted to low-level format them to 4KB sectors.  Most
of them laughed in my face.  One of them tried to comply and
irreparably confused its firmware in the process.

Just yesterday I received a couple of prototype drives in the mail.
I'll ask the vendor whether they support 4KB and if so I'll give them
a whirl.
