I have been running a raid setup for several years now, but have always used a onboard controller. I have never seen as good of read/write or access times as most of the people on ocn that run the same setups i have had.


My question is there any good Raid controllers that dont cost a fortune, and will still be better than onboard controller? I know Perc 5i/6i is really good, but guys on here are putting heat sinks and other stuff on them to max them out......

Anything simple?


Thanks guys

Get an Intel board with ICH9R or ICH10R, better than a lot of older RAID controllers already.

3. For 45nm silicon, 1.45V in Vcore is not unsafe, however 1.3V in Vtt already is.
4. LGA1366 for SLI/CF.
5. Performance Enhance to Standard for memory issues on Gigabyte boards.

All i know is evga boards. what would the model numbers for intel boards be for those chips?

Anything from Asus or Gigabyte, MSI and ASRock (also Asus)..

can you post hdtune benchies so we can see if your board is indeed the culprit.

Also, a correct stripe size selection is crucial in terms of performance. Since this depends on the type of raid, the number of drives and probably other factors, it generally comes down to trial and error to find the best setting.
Did you experiment with different stripe sizes? There's no need to build a full disk array for this, make several smallish arrays with different settings and compare the results. Don't make them too big as HDD performance is not linear throughout the whole drive and it generally takes a long time to build. 5-10GB arrays for this testing step should be fine.

The other half of that is testing sector size. This can be seen especially with SSD.... testing with some sector sizes should crap performance.


Unless you have an EVGA X58 or P55, you have been using NVIDIA RAID. It's performance is decent but not that great.

Lets narrow that to just the newest chipset, ICH10R.

Any MB manfg. that uses an Intel chipset has the ICH10 or ICH10R as a southbridge controller for the HDs.

The only thing to "look out for" is the "R" at the end.

No "R", no RAID or AHCI and you definately want the "R".

That being said, for the time being the ICH10R will best any other software RAID0 controller and there's very little difference if any, from the nice hardware based add-in cards.

If you're matching your set-up "apples to apples" with a ICH10R in RAID0, you'll always lose.

I hate my boards raid controller

ICH10R solutions are indeed performing really well but you won't get away from CPU utilisation (which is basically 0 with proper hardware raid), especially on the raid 5 front.
