If I set up a raid array with 2 new SSDs will i still be able select and boot into my partitions on my HDD ?

So I have 2 240 GB Intel 730 ssds and I was wondering, once I set up my raid array on these 2 drives and install my OS, will I still be able to select and boot into the windows partitions i have on my current HDD or will i need to set my sata mode to AHCI in bios to swap between the 2 during reboot ?

Is there anything I need to be careful of ? I plan to unplug my HDD while i set this up but...should i avoid having my HDD hanging around while RAID is enabled ? Thanks.

I don't know what motherboard you have or anything but on mine I've noticed you're able to set individual or groups of SATA ports (like 1-4 and 5-8) to either be RAID or AHCI/IDE. So you could have the RAID drives on the ports sets for RAID and the ACHI drive on a port set for AHCI. I've never used RAID so I don't know how all of that works really but I just noticed these settings when playing around in my BIOS. Might be worth seeing if you can do the same?

If the raid you setup is on the Intel controller all ports will be set to raid. If you still want ahci in your system it will have to be another controller like Asmedia or Marvell.

Oh ok, well i'm using a asus sabertooth x79 board and it has both intel and marvell controllers, should i just install the marvel ones during windows install ? Someone on another forum said you can just leave it on raid and it will still do AHCI, i'm guessing this is how itll work once i install the marvell drivers?

Your mobo has intel and marvell controllers. You intend to do a raid array with the ssds on the intel controller but already have a hdd on that controller with a Windows install in ahci mode and you want to be able to boot into it as well? If the answer is yes then first you need to enable the marveĺl controller, set it to ahci mode and boot into windows. Install the marvell ahci driver. Reboot. Let it go to windows. Power down. Move the hdd to the marvell controller. Reboot and let it go to windows, you should have no issues. Then setup your raid 0 with ssds on the intel controller.

oh, but i have to split them like that? I had heard on another forum that once you enable raid in bios, you can still access ahci single drives also, but if you enable ahci you can't access your raid array. Is that wrong ?

I was under the impression you ment if i wanted to use both i could only do that with marvell, but now you are saying no? Infact I need to install ahci marvell drivers ...move the single HDD to the marvell 6 gb/s sata port , set my bios to raid, put my SSDs in the Intel 6 gb/s sata ports , set up install the raid drivers during windows install... and then i'm fine ?

Once you enable raid from ahci and boot with the same drive you will get a blue screen. There is a registry hack you need to perform if you want both. Or switch from raid to ahci every single time you want to access that drive. My method is a lot simpler. For a traditional hdd Intel oor Marvell, raid or ahci will change nothing speed wise but for 2 ssds in raid0 Intel or Marvell raid will be a big difference.

Alright then, I didn't even realize ahci drivers existed, but thanks for giving me the heads up. Not alot of info on this on the internet , and i definitely would have been hit a wall without that method. thanks again.
