36GB Raptors Raid0

[Catman05]

Hi
I am having a problem with my two raptors they seem to be performing worse than my 2 Hitachi 40GB drives me it is puzzling me why it is doing this.

I have tested both drives with WD tools and other and both drives seem to be fine hardware wise.
Also just wondering how I should set the jumpers as both drives have different labels one say ssc disabled the other does not mention ssc.

Can someone please help me with these problems?

Thanks
Chris

Hi
Thanks for the quick replies
Have checked the device manager and can't find any settings about transfer modes.

Both drive have been set to pin 1-2 but both have different labels

Sorry about the bad picture quality drive 2 basically says pin 1-2 ssc disabled and pin 2-3 PM2 enabled

Thanks
Chris

Thanks for your replies guys
I have no options in device manager for the controller apart from the 4 default tabs. (General, driver, details, resources).

I can't say that the jumpers where like that when they were new.

I have just run another test with all programs and background items off and I get the same results apart from CPU is now at 11%.

Drivers are latest for both controllers also the mobo and Adaptec card have the latest bios versions.

Stripe size is 64k.

I am going to test these drives on the Adaptec card (which the Hitachi’s are on) but last time I did it the results looked the same as this.

Raptors are empty I don’t know if that makes any difference?

EDIT:


benchmark from the adaptec contoller. The Raptors are in red


Both raptors on the adaptec card in a non raid config.

thanks

Hi guys
Been playing around and installed win 2000 on an ide disk as a second boot and to my surprise win 2000 see's 2 raptors as separate drives but xp see's 1 raid drive which is rather confusing me. Raid is setup in the bios not with the raid utility in windows.

Is this normal?

Thanks

Why have you put your jumper in a different place on one of the raptors? I presume these drives have different firmware?

Hi
I have not owned the drives from new and I was just going on the WD default jumper setting page that indicates 2 default positions for default and I have 2 drives with different labels.
If I set the stripe size to 32 all seems well with hardly any of the saw tooth effect but now I seem to get like 30-60% CPU usage on hdtach?

Thanks
