Inexpensive SATA RAID controller in a server?

Question

RAID

Recommend an inexpensive 2- or 4-port SATA RAID controller without a battery, which would not be embarrassing to install in a server. You need to add two mirrored disks to the server, and all the RAID ports in the motherboard are already occupied. There is also an important condition: since Hyper-V Core 2012 R2 is installed on the server, the controller software must work in this OS (so that you can monitor the status of the disk array using software).
Motherboard X10SRi-F.

Take some HP, you can buy a used one somewhere on Avito. I don’t name the model, take pusho, what money is enough for.
