I had to replace miniSAS with 4x SATA my Dell PowerEdge T420 was kinked like the last one and didn't work anymore. Since it shows it's used to connect to motherboards, I took a chance instead of paying $30 for the official part. This item works, but there is a communication error with the drives that makes it unusable in the T420. I then tried an ASR-2405 PCIe adapter and a pair of ASR-6405 and ASR-6405E PCIe adapters, with which this cable works very well.
