On motherboard RAID Vs. Add on RAID controller

post #1 of 4
Thread Starter 
Anybody have some performance comparisons on this? More specifically on SATA II and a addon controller with CACHE onboard.
I was just curious on how much more to expect if I went with an add on RAID controller.
I'm looking at this card:[ame="http://www.amazon.com/SAS9260-4I-Raid-4PORT-sata-512MB/dp/B002IT4YH6"]http://www.amazon.com/SAS9260-4I-Raid-4PORT-sata-512MB/dp/B002IT4YH6[/ame] but my SSD's are SATA II.

Well, first we would need to know: what southbridge does your motherboard have? And what hard drives do you plan to setup in a RAID array? What type of RAID array will it be and how many drives will there be?

Generally speaking, for basic RAID 0 or RAID 1 setups the onboard controller on motherboards is more than sufficient. But when using two SSDs in RAID 0, you may run into a bottleneck depending on the SSDs.

Nice RAID controllers can be pretty pricey, so you can definitely be paying hundreds of $$$ for that extra ounce of performance. It also comes down to how much you're willing to spend for every bit of performance.

I'm running 2 of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16820233124
And going to add
2 of these: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227550

They'll all be in a RAID 0.
Can't remember the southbridge of the mobo though. It's an AMD board. I have a feeling that I may be saturating the onboard controller because I am getting ~430-450MB/s on my ATTO test. Shouldn't I be be able to at least hit 500MB/s? If I add the other 2 SSD's and not performance increase then my onboard is saturated. Right?
