So, as you can see, I have three RAID arrays connected to the Intel P67 PCH.
Another point to take in consideration is that all my virtual machines are stored on my SSD array for best performance.
Before getting my second Crucial M4 SSD to create my RAID 0, I've read a lot that maybe the PCH would not be able to "follow" the SSD speed. But I decided to get the second SSD anyway to make the experience.
I am now wondering if a good RAID card would not give me better performance for my setup. I have also two other RAID 1 arrays on my PCH, and the first array of Seagate is built with brand new HDDs running barely at 200 MB/s while reading. I think that's a lot for a single PCH to handle.
So, if price is not a real matter (below 550 $ would be correct considering the setup I have), would a RAID card give me better performance ? I was looking for a PCI-Express x8 Gen 3 (even if my system is not Gen3 since I have a Sandy bridge CPU, I would buy a Gen 3 to be future proof) with on-board memory. Would the on-board memory be better for a setup of SSD in RAID 0?
I know I lose TRIM while RAIDing SSDs and bla bla bla I'm a power user. I know how to use my PC and my RAID 0 of SSD. I'm just asking if a RAID controller would give me better overall performance or a significative performance gain in I/O and speed (with on-board memory).
Is there compatibility issues to look for before buying a RAID card ?
I really like the Adaptec 6x05 cards. I have several 6805 on ASUS P8 (P67 and Z68) boards and they work well despite the caution about UEFI with the cards. I would look at the 6405 in the kit form with the .5 meter mini8087 to 4 SATA port adapter (part 2271100-R): http://www.newegg.com/Product/Product.aspx?Item=N82E168...
The performance is excellent, it does require a PCIe x8 slot, and you could throw a couple other drives on the other two ports with another array in RAID 1 or 0 with excellent performance also.
That is true for the 9265-8i, it blows everything away with SSDs in terms of IOPS. If it is in your budget, for SSD use it makes sense, not sure about the I/O advantage with the 9271-4i, but I would expect that it is more optimized for SSDs also and is close in price to the 6405.
I cannot speak to the compatibility of the LSI models though.
