Poor Raid Performance with REVO RAID 64
- Thread starter easyrider
- Start date
If you are using the Nforce 680i LT ( MB-N680-ILT9 ) chipset, XFX suggests you update to BIOS version P04...if you are not using this chipset, check with your mobo manufacturer if a BIOS update has been released fixing any issues with the Revo card or indeed RAID cards in general.
Does the Revo have the latest firmware?
Being on the PCI, your Average read will be limited to just over 100MB/s, so it looks those 2 AAKSs are only giving half their potential transfer rate (with this card)....check the settings again within the Revo options that they are correct for RAID0...unfortunately can't get looking at a manual for this card, as one needs to register on their site for it.

Is the PCI bus really limited to 50MB/s though?
There is something a miss.
It might not be as fast as onboard but thats score stinks!
I just don't get it?
No, it's 133MB/s.

Agreed, the card isn't performing as well as it should and I'm not sure why. It's at times like this when I take a step back and think "is it worth spending x hours trying to fix this or do I take an evening to nuke the PC and start again with a setup that I know would fix the problem?"
Well its not my windows disk.
Its a Raid setup for my video editing so no re-install required.
I thought a Raid card with 64 MB cache wether on the PCI bus or not would be much faster than onboard mobo?
Its bugging me more than anything.
not even high end raid cards give much performance boosts to raid0 over onboard - let alone your cheap card.
i don't think you understand the basics of raid0 if you think cache will make a difference.
just use onboard, you're fighting a losing battle with no victory possible.

Unfortunately a reinstall will be required if you're booting from another SATA drive. The Intel controllers don't allow the switching of individual SATA ports to RAID mode so the whole set have to be in RAID mode. Now you can quite happily run single drives while the controller is in RAID mode but your Windows install will have the legacy drivers installed (I assume) and you can't install the RAID ones without having the controller in RAID mode and you can't boot the system in RAID mode without the drivers installed - a reinstall from scratch is the only simple option.
Now I have another problem...
Sice I'm now using the onboard raid I'm getting rubbish transfer rates with my optical drives
I have one on the IDE channel and the other sata dvd rom on port 2.
PIO is enabled with no option to change it to DMA and ripping a DVD is taking ages.
1mb second read speed
whats going on?

can you set the DVD to DMA via the bios? or try another sata slot.
To get your optical device to run in DMA Mode (having been "stuck" in PIO), simply right click the IDE channel it is on in Device manager, select Uninstall, OK etc, IDE channel will disappear, reboot, which will reinstall it and cause DMA Mode to be available for IDE Channel.

PCI Bus is 133MB/Sec shared with all other devices inc onboard sound/nics etc etc , but should get more than 50MB/Sec.
On my old, build I got 78.4MB/Sec with 1 RaptorX and 108MB/Sec with 2 in Raid0, on a silicon 3122 Sata Raid Contoler onboard.
