Why does SATA create RAID and SCSI entries in Device Manager?

[Bobby]

I installed a SATA hard disk recently and Device Manager now reports a RAID
driver (I don't have a RAID drive) and a SCSI driver (I don't have a SCSI
drive).

I thought SATA was ATA 150 so what's this SCSI stuff? And what had RAID to
do with SATA?

WIndows has two ways of handling drive controllers, either
it's a PATA, or it's something else that needs a driver.
Any "something else" is called SCSI by windows.

The controller is capable of RAID, hence it's a RAID
controller regardless of whether you have RAIDed drives or
not.

My BIOS allows me to enable SATA drivers and also the onboard RAID drivers.
I disabled RAID and everything works fine. Takes longer to boot when RAID is
enabled and I don't use it anyway.

Also a typical example is external harddrives.
