PC Peripherals Doubt abt SATA 2 and SATA 3Gb/s

It says 3.0Gb/s. But I thought the fastest drives were 300MB/s i.e 2.4Gb/s.

So, what is this new thing??

and will this drive me recognised by A8N-E. A friend's freind in the US wants to buy this and he also doesnt think the premium is worth it.

Wotsay guys??

Sata II is 3Gb/s(3000 Mbits/s), Sata I is 1.5Gb/s(1500 Mbits/s)

Reason :

According to the sata specs, the sata encoding is 8b/10b or about 80% efficient encoding so the effective bandwidth or maximum throughput is about 150Mbytes/s for sata I and 300 Mbytes/s for sata II.

OR 150MB/s for sata I and 300 MB/s for sata II

Calculation for the curious :

(1500 * 1 * 80%) / 8 = 150MB/s

where 1500Mhz is the clock, 1 is the bit per clock, 80% is encoding efficiency, 8 is no of bits per byte
