Need affordable, low profile raid controller

post #1 of 8
Thread Starter 
Basically I am using RAID 0 on my AMD motherboard no problems and I am satisfied with the performance. The problem is that with the system bus in FM1/llano based motherboards being tied to one frequency, overclocking in RAID mode is nearly impossible. The raid controller fails with less then a 10% increase in frequency. I am hoping that if I buy a PCI or PCIE raid controller card that it will be more stable.

All I want is a simple RAID card that will perform identical to the onboard raid controller, and without any issues. It needs to be low profile because I am using a low profile case. If anybody could recommend me a good RAID controller for the job I would appreciate it. I would like to spend less then 50$ if I can. PCIE cards are preferred to PCI.

EDIT: Did a little searching, would this do what I need?

EDIT: Did more researching, almost certainly going to get a rocket raid 640. Thoughts?

A rocket raid such as that will be fine for HDD. if you are suing SSDs though, those intels will overrun it. the closest, and cheapest thing that you will get that will handle raid for your ssds is a 9211 from lsi. or a 9240 if you need write cache.
You will be infinitely worse than onboard with that 620, it really is only good for passthrough.

I did some research, and the marvel controller in the rocket raid 620 and other low cost raid cards is why they perform terrible with SSD drives. I did some research and found this review of the rocket raid 640, which I can get as cheap as 99$:

Is it still worth the extra money to get and LSI controller then? Or would a 640 give me pretty much the same performance? Again, I just want to match my the performance of my onboard controller.

you will lose part of your speed in the scaling unfortunately with the 620. Also, the latency will be very high, and that is the main point of SSDs. the latency on the 620 is terrible. poor firmware implementation.
I do recommend those cards all the time, to people who use them for passthrough only. IF you use one for passthrough it will be fine, and you could use a soft raid with it.
however, is you use it for a boot volume, the passthrough soft raid is not gonna work.
i did re-read the first post though, and unfortunately the 9211 and all cards from LSI will not work over 107 on EVGA boards (PCIe bus) i cant speak for other boards. is that what you mean, you want to overclock the PCIe bus?
I have tested the 9211, 9260, 9265 and the areca 1880ix and they all suffer from this. However, if you are just overclocking your chip that is no problem at all. my 920 runs @ 4.6 all day long
its a tough decision, but it depends upon how much you want the speed. A 9211 will just blister those SSDs. you will not match your onboard with that 620 though.
you will lose some in scaling, and the hit to latency would be bad.

comp, the card I am considering buying is the rocketraid 640, not the 620. The review shows that in all benchmarks the 640 was able to significantly outperform the 620. As for PCIE overclocking, unfortunately yes... that is exactly what I plan to do. Everything in an FM1 motherboard is tied to one system clock, even the PCIE frequency, so when I overclock the CPU I essentially overclock everything.

Should I probably expect any and every RAID controller to fail pretty quickly then?

oops...sorry i missed the edit up top. I was looking at the link from the first post and then the 640 bit flew over my head, i apologize. I am not sure how the 640 would do with pcie overclock.
I know that previous generations of Areca cards could do 120 PCIe bus. but they are uber expensive. any of the newer 6gb/s cards cannot handle high pcie.
That is rather unfortunate with your motherboard. Having those buses tied together is unforgiving.
The highpoint might take higher pcie, but i am not sure.
The LSI for sure cannot!

Ok. I think what I need to do is consider one high capacity, high performance SSD drive instead. I don't think I can significantly improve stability on this system with any RAID solution. I will probably just wait until the next generation fm1 processor come out and then see how pricing is. Thanks for the help comp.

Anytime, i agree in your situation that would be the best course of action
