Win 10 file server

[Longbow1]

Ok so I have a few questions for everyone and would love some input.  I have a win 10 pro dual core shuttle xpc and added 2 4TB WD Reds and will be running them in raid 1.  I have a few questions....

 

1.  The original OS was installed to a sata2 WD green 320 using "native IDE" (which i think uses a MBR)  Will there be any advantage to reinstalling windows under AHCI mode?  Should I wipe that drive and use GPT instead of MBR?  Will i really notice a difference? 

 

2.   The onboard RAID controller for this mobo only sees 2TB of the new WD reds.  I wanted to use the onboard controller;  Is there anyway to make it see the whole drive?  Or will i have to using Storage Spaces?  Once in windows i initialized them to GPT and they show up fine.  I made a dynamic volume and then deleted it and used Storage spaces to create a pool and they both worked fine.  Does this mean i will have to use software raid instead of hardware raid?  Is there anyway to make the raid controller see the full 4TB?  (IE formatting and then creating the array?)

 

3.   If i switch the sata controller from IDE to AHCI, I will have to reinstall win 10, correct?  Any pros/cons to that?

 

 

 

 

I have no valuable data on the system at all, so i can do just about anything.  Just looking for advice and suggestions

 

Thanks again everyone.  There forums are a lifesaver!!

Also, if i do have to use software raid, which is better, Dynamic Disk or Storage Spaces?
