Hi Folks,

This might be silly question but if Thunderbolt is soooo fast why not put a hard disk with Thunderbolt inside an Imac iso "old" Sata one?

because thunderbolt is not an interface in itself, it will act as if it was sataIII - ie. no gain.

Because any current S-ATA platter based HDD (almost all nowadays) are not as fast as S-ATA 3.0Gbps (current common interface) even provides, they hardly saturate S-ATA 1.5Gbps (approx. 150MB/s) with their maximum speed of 120MB/s. SSDs are providing faster speeds, but S-ATA 3.0Gbps and 6.0Gbps is sufficient for them too.
