Reloading Windows 7 without RAID
I have a year old Aurora with two1 terabyte drives in a RAID. They are a major choke point in performance and are
noisey as hell. I am replacing them with a single 500G SSD. I reloaded the OS and so far so good, except that
there is a small partition on the drive I did not set up, about 100mb. I went into the setup screen F2 and checked the
CMOS it shows ICH SATA in a RAID not AHCI and the default boot drive is named a RAID OCZ.....Will this affect
the performance of the machine and should I be concerned with the little partition that was created? Should I change to AHCI?
Thanks Much for Your input

AHCI and RAID are essentially the same thing, no difference in performance.
RAID has all the benefits of AHCI and you don't have to have any drives in a RAID array.
Your SSD will work the same in AHCI or RAID.
Just leave it in RAID mode.
The 100MB partition is your boot files, just leave it there.
There are benefits to having them in a separate partition.
Your setup is fine, all is good.
