WIN2K & Fastrak100 TX2 card w/ RAID 0 on 2 80GB Seagate Barracuda IV's... Problems anyone?

[|TOAST|]

Anybody have any problems with the performance of this setup? I've read about plenty of problems with onboard HPT370+ chips. Is it best to pair the drives up on separate conrollers (ie motherboard native one and promise fastrak100 TX2) or all on the promise card as the only drives, both as masters, per each channel? Is the performance (obviously for larger file manipulation) actually better than 1 one these drives as a standalone master on the motherboard ATA100?

you are sheet out of luck (at least for now)

Why is my Seagate Barracuda IV so slow in RAID-0 configuration?



To paraphrase Seagate technical support, the Seagate is so fast that the RAID controller can't buffer the data quickly enough and so the disk has to read everything twice and hence runs much slower. So there you have it: the disk is so fast it is actually much slower. Seagate do not have a firmware fix at the present time as they claim they are waiting "for the rest of the industry to catch up". See this thread at Storage Review forums for more details. The problem has been reported on several different motherboard chipsets and several different RAID controllers. The problem is not specific to ABIT motherboards. Some people have reported success by putting the disks on separate IDE controllers.

in other words, your raid 0 is toast, Toast.

I've read that somewhere but I thought maybe with this controller it would work fine and I've read about using the motherboard's native contorller paired with this controller to work for some but with other controllers... what kinda controller u got Bozo Galora? Anyone else get this setup to work?

These RAID controllers only do RAID between disks that are all connected to the same chip.

You can't RAID between the normal IDE and the RAID controller IDE.

You might be able to configure the RAID controllers as normal IDE controllers and use some
feature of your OS or other software to do true software RAID across drive on different
controllers... but that would ruin the whole reason to do this at all.

Thanks, I thought I read somehwere that this is possible and I now I can't find it.... might have just been for the onboard solutions provided by Promise and HPT for ABIT motherboards...
