Review on 🚀 Enhance Data Transfer with Ableconn PEX-SA134 4-Port eSATA III 6Gbps PCI Express Four Lanes Host Adapter Card - AHCI Port-Multiplier PCIe 2.0 x4 Controller Card by Mario Bullard

Most importantly, the online documentation says not to connect hard drives until the card's BIOS is set, otherwise THE HARD DRIVE CAN BE REMOVED! This is NOT stated in the documents that came with the card. (2) The attached documents state that the BIOS utility is accessed by pressing CTRL-M during POST. THAT DOES NOT WORK! (3) The card does not recognize discs. A card from another manufacturer works fine in the same slot, so the problem is not with the computer. (4) Technical support is only available via email. I've walked this path too many times. This leads to days or weeks of dialogue with Level 1 engineers who typically know nothing about their products. That's not acceptable to me. Going forward, I will try to contact the company's tech support BEFORE purchasing their product and will no longer purchase from a company that does not provide live tech support. It's an old product by computer standards, as the documentation doesn't even mention Windows 10 compatibility, even though Revain's listing says it's compatible.
