Cons: Doesn't work. Wasted several hours trying to get this thing to do anything. All I managed is to have the bios briefly see my HD. Never appeared in the OS and disappeared again after a restart. Tried all the suggested fixes and on multiple HDs, nothing. Either mine is defective or the product is now outdated. Either way it costs too must to return it, so its a complete waste of my money.
Pros: Worked first time, added CD/DVD IDE burner to SATA controller on Gigbyte Mobo. Small size, plugs right into back of drive and SATA cable length is more than adequate. Y-power connect is a plus, plugging into one standard 4 pin molex from power supply and providing power to the adapter and drive.
