Review on 🔌 StarTech.com U.2 to PCIe Adapter - x4 PCIe - For 2.5" U.2 NVMe SSD - SFF-8639 PCIe Adapter - U.2 SSD - PCIe SSD - U.2 Drive (PEX4SFF8639) - Enhanced SEO by Jermaine Rhodes

I decided to save some money by buying another brand card for $10. It was connected to my 400GB Intel 750 which was going to be the OS drive for my home server. After the initial installation, during the setup and "prep" phase, my system froze and I had to perform a hard reboot. I didn't get past the initial setup and it took me a while to run into issues. It was either a cheap SFF-8643 card or my drive (my drive had previously been removed from my working system). Switched to this StarTech card, everything works fine.
