Intel Raid and Windows 10

[JRose18]

I have an ASUS P8P67 REV 3.1 board with an Intel i5-2500K processor.

I have two disks for my data which are joined in a Raid 1 configuration, which is supported by the chipset (P67 Express).

I would now like to change my disks because I think they are in the process of giving up now. I switched from Windows 7 to Windows 10 a while back and during the upgrade the management software for the raid disappeared. My question is, can I install Intel RST driver (https://downloadcenter.intel.com/download/27147/Intel-Rapid-Storage-Technology-Intel-RST-?product=55005 https://downloadcenter.intel.com/download/27147/Intel-Rapid-Storage-Technology-Intel-RST-?product=55005) without ill effect (probably the 14.8.0 version)?

Or is this the wrong software after all and I have to use something different?
