You're gonna need server-grade PCI-E bandwidth. [IBM-ServeRaid-M5110-8-Port-6Gbps-PCI-e-SAS-SATA-RAID-Controller-81Y4481-81Y4482][1]

you'll need to make sure you get some SAS to SATA breakout cables, but these drives offer serious I/O for a decent price. Consumer grade RAID cards usually fail to satisfy your needs because of insufficient PCI-E bandwidth, while modern equivalents will not really be affordable. In my experience the only difficulty is in making sure you get the drivers (but since they are well-supported this is not really an issue after all).

Small note: if you don't have at least one PCI-E 8x 2.0 connection, you're boned. You may also be boned if you have lots of other devices occupying PCI-E slots. [1]: https://www.amazon.com/IBM-81Y4481-Serveraid-Controller-System/dp/B007V8S0HY
