This product works perfectly. Just do not forget, like me ... to feed the cable and read the instructions to select the correct jumper. This is well explained. It can connect either a SATA device on a motherboard with IDE ports, one IDE device on a SATA motherboard. The two SATA connectors are identified, use one or the other depending on the direction of data. The standard is used SATA 1.0, which provides a convenient rate of 150 MB / s. That is enough for UDMA 133 does not exceed 133 MB / s. UDMA100 and 133 are managed. Supply side, there must be two Molex plugs, one for the converter and the other for the HDD or optical drive. Taking on the converter is of the type disk drive. For DIYers, one can weld the son of the diskette provided plug the son of Molex connector from the power supply. The converter is supplied with + 5V only. This avoids the nested taken which take up space and increase the sources of false contacts. Without this, it will take two Molex available. The converter does not require a device driver. In the BIOS / UEFI, the IDE device will be recognized directly as a PATA and not as a SATA. I plugged into a motherboard Gigabyte 970A DSP3A in SATA3, without worry. In synthesis, an essential component for someone like me who gets his optical drive and HDD backup from his old PC. No clutter concern in a conventional tower. Side robustness is of course suitable for a tower, a little less for mobile use because the card is simply plugged into the IDE connector. The product, made in China, comes from the USA and icing on the cake, I ordered 3 and 4 received !!! The delay was just long hair but quite consistent with the information provided. I recommend quite what converter which avoids to scrap IDE devices when changing config, all for a good price / quality ratio.
