On board raid vs Raid Controller Raid 10 performance

[XPLOT1ON]

I am planning to do RAID 10 on the Asus X99-E WS however I can't decide whether to do an onboard raid or use a raid controller (LSI 9260-8i)

I will be using RAID 10 with maximum of 8 SSDs

Which options would be better in terms of overall performance and stability.
The CPU that I will be running is 5930K so CPU taxing shouldn't be a major performance drawback

It will cost you more for a discrete raid card, but you will get better performance.
Raid cards have their own processors and lots of cache for buffers.
Some will also include a fail safe battery.

That's a very good point (battery back up and cache) but how much of the performance difference are there between the two options?

I don't think that is knowable without more on your particular usage.
You might look for benchmarks using the raid card you are considering.
Or, reviews from those who have purchased it.

Do you know the exact model for on board raid for Asus X99-E WS. On the website it just said X99 Express Chipset with RAID

PCIe RAID card with your MB and 8x SSD in raid6 you can get about 1800MB/s at least (ARECA will do that) but LSI my guess should be the same or a tag slower. Don't use RAID10, you are wasting your precious space


When you use RAID on your MB. The RAID won't use much of CPU power, rather too many IRQ of each drive being send to CPU, you CPU ran out of time, not power...

Remember, way back then, when you format a floppy disc, or burn a CD in IDE bus the computer just freeze? Yeap too darm much IRQ
