Slow performance Sandisk Ultra Plus on x58/ICH10r

[EndlessWargasm]

Hi all

Quick question, would the x58/ICH10R be holding back my random 4k Read/Writes?

Most reviews of the Ultra Plus have 4k reads around the 30MB/s and writes around 100MB/s

I'm getting about 30% less than that. 19MB/s and 70MB/s respectively.

Thanks

Yes, it will. Newer chipsets are better optimized for SSDs (TBH, I think most of it is just running the controllers faster, and with more total bandwidth). ICH10R is a ~2007 vintage south bridge.

If your board has a 6GBps controller, and it's not buggy, this would be one of those cases where it could be better.

Are your sequential numbers around 250MBps?

Yeah, right around there.

Thanks for that. I was worried that Sandisk had screwed me over a little extra.
They sent out a batch of Ultra Pluses that have old pre release firmware, that is not upgradeable.
Well, not upgradeable any more, the first one I recieved was bricked by their tool kit when I attempted to upgrade it, their new software doesn't allow that any more at least. The replacement they sent me has the same damned firmware (v 10.03.00) however.

My first benchmarks were worse than those up there as I was using the built in win 8.1 drivers for the ICH10R, I had to dig around for some modded ones to get up to the speed I have now. Random 4k reads were ~12MB/s which is just terrible.


Anyway, thanks again for your help.

Those look about right, I think. You'd get nearly double the sequential read speed, and +30-50% on the others, if you were to upgrade to a current-gen chipset from Intel or AMD.
