I think what has happened is that Intel has sent out some SSDs, both review units and some to the retail channel, with instructions for no one to disclose anything or sell anything until some future date. Rumor has it that date will be sometime next week.
But whoever at Intel is in charge of marketing the 520 should be fired. It is idiotic to send out any units, whatever the precautions, before officially announcing the product. The SSD marketing people should try to be more like the CPU people. Ivy Bridge is not due out until early April, but we already know most of the specifications.
By the way, the benchmarks have been posted by "DooRules" on xtremesystems.org. I'm not sure whether groberts101 is just reposting the links to the images, or whether he and DooRules are one and the same.
