Shocking RAID1 Performance on NVIDIA 680i

m3lv1n · 5 Jan 2007 at 16:04

I have 2 x 120GB WD Caviar SE on my 680i in RAID1

Just ran a quick check using HDTACH the numbers are horrific.

I used to use the exact same disks on my MAX3 with a Sil 3114

the Sil 3114 60 to approx 35MB/sec seq read burst 120MB/sec ish

I mean omfg that is nasty

The array isn't in rebuild or anything.

Anyone else using RAID1 on this board.

Cheers

I read an article about raid performance yesterday between 680i p965 and p975 and there was some issues on the 680i implementation.

Can't remember if it was tomshardware or anandtech, but I'm sure you will find the correct site if you want to have a look.

Im busy shutting down my work comp so dont have time to check which is the correct site

raid 0 is fine for me, cant comment on raid1 performance
You should check yir raid settings and disable ncq if the drives dont support it maybe ?

My raptors are on as single disks no raid the performance of them is fine.

How do you disable NCQ on the system though I can't see how this would make a difference surely if the drives don't support it just isn't used.

8mb cache raptors dont support it, its enabled by default with this mobo for some reason and when you use hdtach yir burst speed is 9mb/s

Its in the device manager sata and raid controllers, if your drives support it , that shouldnt be the problem.

Windows setting.

Under Disk Drives

For Nvidia Mirror disable Tagged Queueing?

Can you confirm its that setting.

Cheers Mate

Ok sorry under SATA section.

The raptor has command queueing enabled but the caviars have the box greyed out so I assume is disabled.

The raptors are fine but I was thinking to RAID them later this month. If I do disable the queueing?

All are running at SATA 150 which is to be expected. Dam I'm not sure how to fix this. Its not a big problem as I only use the caviar's as a mirror for backups just a bit odd seeing as they were twice as fast on my old board.

Must admit my SATA raid experience is limited to proper hardware controllers Eonstor and 3ware at work. I have tried a couple of onboard ones so far the Intel ICH series seem very good Sil not too bad but these Nvidia ones totally suck TBH.

Thanks

Device manager, SCSI and RAID controllers section
if yir drives dont support it disable it, and run the hddtach to check. Im not sure if the 16mb ones support ot or not... Cant do no harm to try anyway.
