A7V333 Raid 0 VERY SLOW

[TheMaverick]

This is terrible lol. I am testing very badly on the hard drive bench marks. On Sandra I get like a 20000 when I should be getting like nearly 40000.

Anyone else having this problem or know of a way to speed things up a bit?

I have 2xMaxtor 20GB ATA 133 7200 RPM hard drives in the raid 0 array.

Check your DMA settings for the drives. They may be set too low or stuck on PIO or something similar. Also what size stripes are you using in your raid settings?

I have a promise raid setup it wont let me set the stripe size instead it gives me 3 options. Perfromance, Server, A/V editing

I have tried 2 of them and I score the same (Very low)

Hi, I have the solution to what should be considered a bug in the VIA chipset or more probably in the chipset that control the USB 2.0.
If you want good RAID performances, you must disable the USB 2.0 controller through the jumper or more easily via software through the system property (right mouse button) on the desktop.
I own a A7V333 with RAID onboard that I disabled just because I also have a Fasttrack100 TX2 but the problem is exactly the same. Also install the patch rpp1.02 because it gives 11% more resources to the RAID controller.
The OS is Windows 2000 Pro SP2
Read here:
2 Maxtor Raid 0 Promise Fasttrack 100TX2 Sandra 2002 scores 24000
After I disabled USB 2.0 Sandra 2002 scores 43000

2 IBM 120GXP 120 GB Raid 0 Sandra 2002 scores 32000
After I disabled USB 2.0 Sandra scores 48500
overclocking the system with a FSB of 149 MHz and USB 2.0 disabled Sandra scores 53500 (IBM)
I disabled the USB 2.0 through the jumper in order the controller be invisible to the OS.
Please go in the Viarena forum and ask for a patch. Perhaps one more customer will convince VIA to release a patch if it is possible

WOW!

Thank you so much I am able to test at 32000 which is a great improvment over 20000. That is while running some programs and a download so I should be able to push up to 35000 maybe more.

Thank you very much.

You wouldn't be able to e-mail me that patch would you.. I am checking on the forum for it currently so if you can't that is cool too.

You may get the patch at this URL

May be I was not so clear. At Viarena page you will find a patch to give 11% more bandwidth to the RAID controller.
But the problem still remains. All the owners of a via-based motherboard and particularly the board using the KT333 chipset, should ask to VIA for a NEW patch to solve the problem that slow down the HDD performances due to the USB 2.0 device. This patch, whether it is feasible, has not yet been released.

You can't adjust the DMA in raid.

I've got an Asus A7V333, and 2 IBM GXP60s in Raid 0.
Running Sandra after a fresh install:
30,000 / sec

After the Raid patch from Via (as mentioned above)
40,000 / sec

After disabling USB 2.0 (thru System device manager)
48,000 / sec

throw away your mb, your hds or both. hehe.

*sigh*


I'm not sure who to spite/damn:

1. Asus
2. Via
3. msft

The numbers sound good. 48000 is a good result for two IBM 60GXP in RAID 0.

 

[TheMaverick]

Too bad I can't get a score like that with a maxtor

I am now running an MSI 6380E and I score at like 37000 I can't quite figure out why I am running this slow can it be the hard drives?? From my understanding Maxtor is a great brand was I mistaken?

37000? That's a score with Raid0? I think that would be pretty respectable. Remember, you're not going to double the performance with RAID, so don't expect to. What does just one of the drives score?

 

[Jeff68005]

Sounds like a good poll question to me.

Using SiSoft Sandra 2002 to benchmark a RAID 0 array (2xUDMA 100~133 hdd), you should score about 48000÷50000 on a A7V333 + 4in1 4.4 P3 + rpp 1.02, after a clean installation of W2K and USB 2.0 disabled.

perhaps a via problem i have heard of the like. try getting a bios update for your mobo or new via 4 in one drivers.
