Problems with ATA100 RAID Controller

[iks 0]

Hello there,

 

Recently I bought ATA100 RAID Controller (Dawicontrol DC-100 UDMA-100 controller with Highpoint chip "HPT370") so I striped my two 80GB Seagate HDD drives in one 160GB Array.

Now in my case data blocks are written inteleaved between 2 disk drives, so the performance shuld be nearly doubled...

BUT the performance is actually really bad. I mean everything works so slow, much slower than before when my two HDDs were connected to primary master and primary slave IDE controller. I reinstalled my WindowsXP with no luck... It still takes ages (for exaple to copy something from one partition to another and when I am copying something everything else works really slow, for example I hardly open my email client when another application is accessing HDD at the same time.

 

Does anyone know what shuld I try to do?

Any tips and tricks?

 

I know it shuld work faster...

 

My configuration is:

 

- BIOS Setting Utility on my RAID card is version 2.31 (and can't be flashed to newer version),

- WindowsXP Drivers are version 2.34 (also tried 2.31 since same versions are recommended but with no luck)

- ATA RAID Management Software is version 2.31

- My HDDs are connected:

- one to primary master and another to secondary master on RAID controller (as it is said in User's Manual)

- My CD-ROM and DVD-ROM are connected to Primary and Secondary Master on IDE controller

- My CPU is Intel Pentium III 800EB Mhz

- My Mainboard is ASUS CUSL2-C (Black Pearl)

- 512MB RAM, ...

 

Thanks,

It is a known issue that Seagate harddrives works like shit in RAID. U cant fix it. Its something with the firmware in the seagate harddrives and seagate themselfs have been unable to solve it.

good job i didnt get 2 seagate drives then, i nearly did coz they were going really cheap. glad i got the WD, amazing speed. Striped raid and i can copy 271mb file in 3seconds to my IBM 80GB also on the raid controller on IDE2. Raid is fantastic

Yup. Basically, use the card as extra controllers (for your HDD's only) or get some different drives or see if you can get your money back on the RAID card.
