There are a FEW of the new SSD "drives" that can come close to the 3 Gb/s data transfer rate
Uhm, no? In a SATA II/3.0Gbps the maximum transfer speed is 300MBps. My old Samsung 470 SSD can hit this. I think it's rated for 280/240 read/write. The newest SSDs on the market can do 550read and some can hit around 400MB write. It won't be long before we need to get SATA speeds even faster then 6Gbps.
