This is a small converter board that allows use of a sata device via an ide motherboard connector, or ide/sata. It works well at its given task.
It is quite well made, comes with a power connector - converter board to molex and a short sata cable. One thing to be aware of is the size of the converter board, no problem when installed in a larger case but might be a problem in a small case or with certain connector layouts on smaller or crowded motherboards. The converter is about the size of a matchbox, but thinner.
one side of the connector has an ide plug, the other side has two sata connectors, which one you use depends on what way round you are 'converting', and a jumper for master/slave selection. That's it, very easy to install.
All in all a good bit of kit, cheaper than throwing away a drive when upgrading to a new motherboard which has only one ide connector.
