Is this the correct RST driver?

Hey all,

Today I noticed on the Intel website there's a newer version of the Intel Rapid Storage driver (see here:

http://downloadcenter.intel.com/Detail_Desc.aspx?agr=Y&DwnldID=22271&lang=eng&OSVersion=Windows%208%2C%2064-bit*&DownloadType=Drivers).

My problem is, I'm not sure if this is the right RST driver for my pc.

I have an Asrock Pro4 Z77 mobo with a Hitachi HDD in AHCI mode running on Windows 8 Pro 64 bit

Also, I noticed that the driver in the link is an AHCI version.  A while ago I installed a RST driver without checking if it's for RAID or AHCI.

I looked in the Device Manager and I saw that the Storage controller seemed to have a Microsoft driver instead of Intel's RST. That is when I thought (and I could be wrong) maybe I've installed the wrong (RAID) driver. The IDE ATA/ATAPI controller group showed that I have an Intel 7 Series/C216 Chipset SATA AHCI Controller.

If the driver in the link is the correct one for my pc, is it safe to uninstall the old one and download the new version?

Thanks in advance,

John
