I've generally found the ASMedia ASM1083 / ASM1085 AHCI controllers stable and reliable. ASMedia is part of Asus, and from Wikipedia: "[ASMedia] produces designs for USB, PCI Express and SATA controllers. Excluding the X570 chipset, all of the AM4 chipsets for AMD's Zen micro-architecture were designed by ASMedia" The ASM108x are only PCIe 2.0 x1 <-> 2 SATA port cards, however there are designs (e.g. "SA3008" - around $45 online) which incorporate multiple ASM108x behind an ASMedia PCIe 2.0 bridge if number of available PCIe slots are an issue.
