If the SATA III format is now frozen and defined, there are currently no products available on the market with such format. Things might quickly changed following the recent announcement by Marvel of a new chip. Once installed on a motherboard, it will provide support for 4 SATA III ports in addition to 6 SATA II ports.If the SATA format was more than enough for disc-based HDs, the development of SSDs and their rocketing reading and writing speed (around 300 MB/s) push the SATA II format close to saturation. Thankfully, the new SATA III will offer 600 MB/s, and should allow computers to work with SSD without being slow down by the limitations of the bandwidth. But, if SSD manufactures keep racing to always look for the fastest models, transfer speed might reach 400 MB/s or more. It is only a matter of price of components and efficiency of controllers that are currently limiting performance level to 300 MB/s one should not forget that most 2.5" HD hardly reach 60 MB/s
