Should I get a RAID controller?

[davidst95]

Hi,

I have two 512GB Samsung 550 Pros running in RAID 0 and two 4TB WD Black hard drives running in RAID 1. I'm using the Intel RAID that's on my motherboard (Gigabyte GT Z97). Would I see any performance improvements if I get a dedicated RAID controller? Do motherboards RAID setup use the CPU? I'm kind of newbie with RAID controllers. Thanks.

Its not worth the cost in buying a raid controller, you might see a little performance boost but nothing to shout about.

I have had nothing but trouble with my cheap one (can't remember manufacturer), I would just stick with intel for just a 2 drive setup. If you end up with more drives it might be worth considering but don't buy the cheapest.

Ok, thanks for the advice.   I'll hold off on getting one for awhile.

Don't worry, no need for a separate controller for RAID0 or RAID1.

 

RAID5 or 6 is a different story, since the parity calculations for these need more performance for good write speeds.
