Something tells me this product belongs to the Too Late To Market Department. $1,000 for a dual-drive RAID0? Well, it's based on Thunderbolt tech. But I can't imagine someone opting for that if they've got two 3.5" internal bays available and could RAID0 a couple of 1Tb WDs instead for twice the capacity and somewhat better speeds.
Of course, if you had two 3.5 bays, that means with $10 sleds, you can convert those into four SSDs - with the 256Gb SSDs in the sub-$200 ($150?) range, the capacity would hit that 1Tb range but considerably faster, and still be less expensive.
I guess anyone who has over-spent for a Thunderbolt port in the first place would need to justify that expense so they'll spend a lot more. That's the Gracie Allen School Of Economics.

"Gracie, you just spend $8,000!"
"Yes, but if I spend $12,000 more, I'll save another thousand! That pays for the new washer!"[/I]
Even the 1943 crowd understood this joke.
