Velociraptor 150 gig vs 2 raptor 74gig raid 0

I have been having troubles with my new setup. Cannot get my older 74gig raptors to setup in raid 0 on my new Asus MB(See here if interested http://forums.speedguide.net/showthread.php?t=264670

So I am thinking different MB or the newer 150gig Velociraptor 150gig. Its a 3Gb/s vs my current 1.5gb/s tx speed.

I am looking for the best possible speed. Example which is fater for unrar'ng a 1.4gb file. My old raptors in raid 0 did pretty good. Would a new drive be faster. I know in terms of the OS loading and basic MS office stuff probrably not much difference. but when its all out unrar'ng a file which setup would be best?

I usually partician for 45g os. then about 103 gig for working area. I have a 500gig sata drive for long term and back up.

Thanks

If I understand your situation correctly....

Not all onboard motherboard RAID controllers are the same. It would be best to do a cloned back-up your data on the older system, then reinstall it on the new with the 74G raptors reconfigured to the new board.

If you want speed, look into RAIDing solid state drives. $350 can fetch a pair of decent 60G drives.

Thanks for the reply. Data is now lost. I did full formats on these drive to try and make them work. I backed up all the data on a spare drive when I was planning on the new system.

Even with the new MB. When I first put the drives in I did a raid format or what ever the bios did for a full delete. Took about 15 minutes. Then rebooted. And freezes affter displaying Raid 0 148 gig functional.

Drive will work fine and solo or in a raid configuration in a different PC.

quick search got a couple benchmarks for the 150 gig raptors. i would encourage you to look around as well, as numbers tend to vary a little.

bear in mind RAID comes with overhead, 'specially consumer-grade integrated controllers. a single drive config doesnt tap the CPU as much, freeing up resource for other things.

I just picked up the Velociraptor. I have get this pc back up and running. I have a benchmark of the old setup. Raid 0 with the 74 gig raptors. I will benchmark this setup when up and running smothly. It will be a long night
