My question has been asked by a lot of people in support groups across the web but there is such a mixed bag of answers I still don't know what the right answer is. When using a ssd drive which is best to use...the intel ahci driver or the default Microsoft ahci driver? I do not use raid. I have always owned intel boards and always used intel drivers but have never had a ssd drive before. Right now it's working fine with the MS driver but I didn't know if I would get more benefit from the Intel one.

What is the make and model# of the SSD drive?
A driver is a computer program that operates or controls a particular type of device that is attached to a computer. Unless you are having issues with your current driver, there is no benefit to which AHCI driver you use, unless you are having an issue with the device.
Depending on the model of the SSD, each manufacturer has their own software package that can be downloaded from their site, like Samsung Magician or Crucial's Storage Executive, It offers TRIM and Firmware upgrades, and other performance enhancing features

MS AHCI enables Trim and the ability to update SSD firmware.

Intel/3rd party driver versions are a mixed bag, some work fine other versions block both. All 3rd party drivers are an addition to the MS base drivers anyway, even if they improve performance slightly, they're also slightly increasing the chance of 'clashing' with other 3rd party drivers.

Generally for Windows stability, the fewer 3rd party drivers loading, the lower the chance of instability and errors. Be aware that each major update of W10 could 'update' your MS drivers to Intel.

I say leave it on MS AHCI drivers. The slight improvement on performance is insignificant and not worth the trouble. I have had my fair share of BSOD grief with Intel RST drivers (comprised of ahci and raid drivers) on my 3rd-gen intel hardware running Windows 10. The latest Intel RST drivers for my hardware were published six years ago, and while they ran ok on Windows 8/8.1, things changed for the worst with Windows 10. If that slight improvement bugs you (I understand the struggle if you're a perfectionist like me), first check if there are up-to-date drivers published for your hardware and OS. Sometimes even the updated drivers won't spare you from problems, especially with other third-party drivers and software on your system.

Thanks y'all. I trust the answers I get here more than anywhere else. I am going to stay with the MS driver. As you say, any, if at all, benefit I MIGHT get from Intel's driver would not be worth any possible headache using it might cause me. Besides, I've already gained so much by installing the ssd I'm not going to look a gift horse in the mouth. Aren't these the greatest things since sliced bread?
