StarTech.com 40 Pin Female IDE to SATA Adapter Converter - Connect a SATA device to an IDE controller - IDE to SATA Converter (IDE2SAT25)

I used this adapter for an old Amiga computer as an upgrade, and it works fine though it needs a bit more adaption to fit.

Was not exactly what I expected but works just fine às I had the space.

This adapter didn't need to do much to earn a five star rating from me. I needed to add SATA support to a Mini-ITX based system with a very low profile case, and that had no clearance for the majority of adapters like this that plug directly into the motherboard. With this one the height of the adapter when fitted is no more than that of a DIMM module meaning that it will fit happily into such a case with limited vertical space above the motherboard.On fitting it and powering it up the adapter and disk attached to it seemed very fast - much faster that the disk they replaced. However after perhaps an hours use errors began to occur slowing the system down ultimately to the point where it was effectively frozen and even a controlled shutdown was no longer possible. Put simply, the system was unusable in that state.Looking into the errors I got and online it became apparent that all DMA and Ultra DMA modes are unreliable with this adapter. DMA transactions are requested but do not complete. The only way around that is to switch to the more primitive PIO modes to control the new disk. That entails a huge performance hit: this interface is supposed to be capable of transferring data at 133 MB/second. In PIO mode I was barely getting 3 MB/second, and PIO needs a lot more attention from the host computer to get even that. I gave up and installed a PCI SATA adapter for the new disk, which worked flawlessly.When performance drops a couple of orders of magnitude from where it is supposed to be it is no longer suitable for a primary disk drive, and the adapter was effectively useless for what I wanted it for. I'm being generous and giving it two stars because the physical size of the adapter can resolve a knotty problem of insufficient space, and in certain applications such as archival or backup maybe those speeds are acceptable. However, those are specialized uses and I wouldn't recommend this adapter for general use.

I have tried these in a number of circumstances and configurations and I cannot get any response from them.
