Will keeping my BIOS set to RAID affect my new SSDs performance?

Hi Everyone,

On my Windows 7 (x64) computer I have just migrated from a RAID0 array to a Solid State Drive. My computer is about 4 years old, and when I built it RAID0 was a good answer for increasing system performance. Of course SSDs have come down a great deal in price over the last couple of years so upgrading with an SSD now makes sense.

The motherboard in my computer is a Gigabyte GA-EP45-UD3R and it is currently set to RAID within the BIOS. More specifically I have configured a single RAID0 array using two hard drives (to boost read / write times).

It is my understanding that in order to get maximum performance from an SSD the correct BIOS mode is AHCI. However if I set my BIOS mode to AHCI I will no longer have access to the data on my RAID array.

Will leaving the BIOS set as RAID (rather than setting it to AHCI) reduce the performance and / or longevity of my SSD?

Any advice here will be greatly appreciated.

Kind Regards,

Davo

AHCI is a subset of RAID. Any drive connected to a SATA port in RAID mode will automatically default to AHCI mode if it is not part of an actual RAID array.

So your drive will operate normally.
