Don't forget to set the board to use RAID if you ever want to use RAID in the future.
Choosing AHCI will not allow you to do this in BIOS, although it may be possible
in the OS via the alternative software method but I've made this mistake and I believe it
can be worked out by using the microsoft 'fix it' or the registry fix that is similar to
when having to set AHCI after the OS was installed in IDE mode. At least I hope it works
like that, I'm about to give it a shot....
Here is a link to the Microsoft
Fix IT article with the manual how to:
Windows 7 to me Samsung 830, I made sure there were no partitions and just clicked next
and let Windows set aside the 100MB backup recovery partition it so likes and also of
course the main installation partition automatically. I didn't have any problems. I did
read this article beforehand. SSD Optimisation
Now I'd recommend you take
certain things with a pinch of salt. I've done a fair share of the tweaks but YMMV.
I hope you get it resolved. I hope I've helped somewhat.
EDIT, sure enough utilising that Microsoft fix has allowed me
to change from AHCI to RAID on my system.
