Question on ICH10R and RAID

[Bojamijams]

Would it possible to run 2 SSD's in RAID 0 and also 2 WD640AAKS in RAID 1 all off of the ICH10R on any X58/P55 mobo?

Or can it only support 1 raid ? Ie. Either the RAID 0 or 1

Well, transfer rates on that chip are capped at 600-650 MB/sec, so depending on which ssd's you selected, you might be pushing the limit when transferring onto your other raid 1 array.

(My source: Intel ICH10R RAID 0 limitations with SSDs - Xtreme CPU)

As for the ability to run both raid types at the same time ... sorry, I don't know.

Good find, at least I know there's no point in going with more then 2 SSD's, not that I was planning :)

But the speed limit shouldn't affect Raid 1 if I'm not doing anything but basic I/O on the Raid 0 right?

Then again, instead of spending money on 2x 80gb SSD's and dealing with all Raid 0 cons, might be better to just get a Fusion IO 80gb instead.. only slightly more but also faster..hmmm

True, the speed limit will only come into play in the situations where you would be transferring files (lots of them at once or very large ones) from your main drives to your backup.

The 120Gb vertex drives are very appealing, bit more storage than the intel's with faster writes. Or maybe something with the second gen samsung controller? I believe the second gen corsair's are running the samsung controller, and they perform at least on par with the indilinx controllers.

Actually, three SSDs seems to be the sweet spot for the Intel ICH.

Remember also that the 650MB/sec limit only applies to larger sequential transfers. Small file transfers come nowhere near saturating the bandwidth.

^^ I agree, good points.

You can have as many separate arrays as you have ports. I googled your question and found guys running 2xraid 0 and 3xraid 5. And a guy running 1 raid 0 and 3 raid 1 arrays.

Thanks :)
