Review on Enhance Your PC's Storage Capabilities with StarTech.com 1 Port eSATA + 1 Port SATA PCI SATA Controller Card by Steve Yang

This does not work on newer Linux kernels, support told me that an older kernel is required (see ST website for information). This driver is built-in, no need to download a driver and play around with Linux. But that's not the case with the new Linux. I couldn't even learn enough to get something to work/mod with. They only have a Win driver, but Win10 will probably handle that on its own. TBF is PCI so I shouldn't be surprised but the product description should really make that clear. The vendor in the Q&A said it works for Linux. StarTech support is really good, chat in seconds, knowledgeable specialist. Revain "Tech Support" is headed for something like this. Told me to download "Linux 2012". which is no problem. Luckily the return wasn't a problem.
