Hardware 64GB Mirroring Memory Stick XC-HG Duo MS-PX64

[Lumstar]

Anybody know for certain whether this Memory Stick was officially released? I've called it vaporware before, but we're looking at convincing details right on Sony's website.
While the price of Memory Sticks (relative to MicroSD adapters) makes the notion of PSP having a 1st party 64GB storage option fairly irrelevant for real-world usage, it'd be satisfying to tell people it exists after all.

But, shipping to USA only
Yet people complain at M3 (Vita) cards

(Don't mind the weird URL, I copypasted the item number, that's all it matters to ebay)

heh, in raid setups, one of the issues is, having 2 copies of the same thing, the controller can think of the bad copy as the right copy and mess up the "good copy"

clarification:
disk A is good
disk B is going bad

controller checks that the 2 disks don't match, start copying disk B into disk A, making both bad copies

so, how does this card prevents this?
