SATA3, eSATA, SATA-6GB ???

i searched some port multipliers and they all took SATA2 input and split it into SATA1.
You might in theory make them identical on both sides, but that is not what i saw on the market.

It splits the sata2 bandwidth is 300MB/s / drives using it. So if you have 4 drives on the port, but only one is active, that drive has the full 300MB available to it. Much like L3 cache on nahalem. Its dynamically allocated.

You dont see the frankenstein hardware you mentioned because it makes no sense. X58 doesnt have AGP support and IDE doesn't have NCQ.

1. I know what it does and how it works. I am saying all the ones I see split SATA2 into multiple SATA1 ports. I haven't seen one that splits it into multiple SATA2 ports... it could exist, and could be used the way you described though.

2. And neither will you see such Frankenstein hardware as a SATA3 port splitter any time soon.

There is one right here: http://www.siliconimage.com/pr...s/product.aspx?pid=154

That is a chip by SI that COULD be used by MOTHERBOARD MAKERS to build a port multiplier into the mobo. It might allow for the existance of a port multiplier that takes an actual SATA cable as input. But I have yet to see such a device ON THE MARKET.
Show me a store selling a port multiplier that is SATA2 to SATA2, not a chip by a hardware maker that could, maybe, be used to design and build a port multipler.

now that is the correct device. I guess it exists after all.
