Many of the SATA HBA's I have seen so far consist of a standard
PCI-to-ATA Controller chip, such as an ATA-100 or ATA-133
controller, which is then connected to an ATA-to-SATA bridge chip.
Thus the software is talking to an ATA HBA and doesn't know that
the drive is really a SATA drive.
The newer generation of SATA Host Controller chips will likely
be totally integrated, but internally they are probably very
similar to the combination of an ATA controller and a bridge chip.

Thanks Gary,
But the Serial ATA spec does not talk about the software much. It says its software compatible with the predecessors. But I am not sure how it is done. Do you know any pointers where I can get more details on the Serial ATA HBAs and their standards ?

- Hi ,
- Can I discuss regarding Serial ATA here ?
- If yes here goes my questions.
- I heard that the SATA is software compatible with Parallel ATA. But how far it holds good in terms of devices per channel (port) ? I heard that they are also working on the Hubs with which you can connect more devices per channel. Is this true ?
- Anyone knows any info on this ?
- Your help is highly appreciated.
- Thanks,
- Gana
