AMD & RAID Performance

[Compman55]

Intel since the ICH5R really ruled in terms of RAID 0 performance, and onboard SATA performance. With AMD purchasing ATi and now making their own chipset line, how is their RAID these days?

I have a 990FX board - once AMD finally enabled read ahead and write back in the raid rom it helped, but I think are still running behind Intel when using a similar setup.

For my particular use it isn't a factor though as the AMD raid is still pretty decent and I like the fact that this board has 6 of the SATA 3 ports.

It would be interesting to see the actual numbers though on similar setups.

How about thier onboard SATAIII? Compare to intel?

I had an 890fx board and I found the performance was much slower than my Intel P45 based board (with a single drive). So slow in fact that I ended up building a 3 drive raid 0 to get around the performance problem on the AMD platform. This gave me about 150% of the performance of a single drive on the P45. I then moved to X58 and kept the raid array which further increased the performance.

This was all on my server (listed below) I use the space as a temp and scratch location for new data, the AMD system really pissed me off because of the hdd performance! In fact it was a great reason to put my X58 into the server and upgrade to X79 🙂
If you are looking at getting new gear and are hdd bound, I would suggest staying with Intel.

I have an 890FX and no complaints. It's more than fast enough for what I do. I use my PC to "work" 6 days a week often moving large amounts of data and don't feel I am being held back in any way.
