Raid 0 Problems

post #1 of 4
Thread Starter 
Hello,
I am new to this forum but i consider myself to be quite experienced in the bios and software education to build a computer from scratch and have it run exceptionally well. You could call me egotistical there, i would take it as a compliment. However, i do know there are some things i overlook and this is why i am here.

I have built 2 computers recently with the attempt to install Raid 0 in them with Raptor 10k's and have failed both times. The term fail here is that it does not perform to my liking or similarly to my 3-4 year old rig with the A8N32- SLI deluxe. Its old but it can boot from power up to desktop in under 15 seconds in Vista x64 with 4g ram. Moving on to my issue...

I love AMD and will never (hopefully) move away from them in the future and first built a "Spyder" rig with Phenom I 9750 on the MSI K9A2 Platinum. 2 Raptor 10k Drives, 4 Gigs of Crucial Ballistic RAM, and an MSI ATI 3750 video
card. Working backwards from current, the system runs outstanding with Vista x32 and 1 Raptor HD. Once i attempt to RAID 0 2 raptor drives, not only does the installation take forever, the time it takes to even boot the machine becomes so unbearable its annoying. I have played with the raid 0 settings a thousand times. Formatting hundreds of times and resetting my array dozens of times each time i format and reinstall. The board has 2 raid controllers and i disable the Promise and use the AMD controller.

To make matters worse, not intentionally, i figured that it had to be the motherboard. I purchased a Biostar TA790GX3+ and i get the SAME issues. 2 Raptor 10k drives raided in RAID 0 and boot time takes roughly 30-40 seconds with lots of time were the drive activity lacks so it seems that it is waiting for a time out of some sort.

To sum it all up, i am doing something wrong when attempting to raid with AMD motherboards. I have tried both onboard controllers with the FX board, changing bios settings from what i konw to nearly guessing to see if i land in the answer. I have attempted to move the drives on both boards from slots 1 and 2 to all over including the reccommended 5 and 6 slots but i STILL get the insanely slow boot.

As a final note i installed SiS (sandra) to see the speeds at which my 2 Raptors perform and installed it on my 4 year old rig running the old Nvida 590 chipset (contorller unknown) and both AMD rigs are getting 55-60 mb/s at Raid 0 while my 4 year old nvidia 590 rig is pulling 130-150 mb/s....

If ANYONE has any ideas what i am doing wrong on these boards, please let me know. I am missing something and i cant find a single person that is having the same problem.

Thanks for reading and replies.

The first thing I am going to ask is what stripe size did you choose?

128k is the best all round for most. A smaller size will be making the drives effectively "Rush around splitting the data between them" whilst the larger 128k size allows them to read/write greater chunks of data in one place before moving over to the other drive.

To put it simply, have you set the stripe size to 128k?

Yes i set it to 128k. 64k was the only other option and i know that bigger chunks are better.

Any more Feedback? Raid 0 is quite simple and yet its giving me so much trouble.
