Question 1

Will it slow down speed? Like bring down speed of a 6Gb/s hdd?

Accepted Answer

I use this extending sata cables.  Sata cables are designed with the correct resistivity for their length for the transmission rates they are specified for.  I have never done specific bench marking with this but if you are running 6GB/s and needing that performance I would suggest finding a 6GB/s cable long enough to meet your needs.  I doubt this part has the correct amount of gold in it to support proper termination and transmission rates.  6GB/s is a rapid speed for communication and as any other transmission line length has a exponential decay in signal causing latency to increase.

It works good for making a 3FT Sata cable but if you are truely looking for 6GB/s I would locate your hardrive close to you MOBO.

Question 2

I have a sata drive in my older machine.  I need a coupler for 40 pins with male one one side and female on the other to plug into the ribbon instead of the mother board.  This is to get a second hard drive in line so the sata drive will recognize it like my previous C drive did.  Is there such a thing?

What you describe is not a SATA interface, but the older ATA (or IDE) interface that uses 40-conductor ribbon cable.  What you actually need is a ribbon cable that plugs into your old motherboard and that has two connectors for the two ATA drives that can be connected, one programmed (with a jumper) as the "master," and one as the "slave."  Newegg has lots of these cables for sale, do a search on "IDE ribbon cable."  One example is item #9SIA1K60TM9784.
