I would say that 6Gbps they advertise it's because it's SATA 3, and more than likely will never actually reach that speed... 6Gbps is equivalent to 0.75GB/s, or 768 MB/s. I think I've seen some of the best SSD's out there can give about half of that value on their peak maximum transfer, but I may be wrong, technology is always going forward.

And I can't believe they advertise it as "World's First".. I'm pretty sure there are other SATA 3 SSDs out there already... I think the "World's First" might be because of the size, 90GB is not common, as SSD makers like to play with numbers of powers of 2...Common SSD sizes are 2...4...8...16...32...64...128...etc
