DFI ultra-d

This board has sata2 right. I just got 2 320gb seagates and want to run them with sata2. i took the jumper out after i set up my raid array. that shouldnt affect anything thought, correct? Thanks for your help.

That DFI has native SATA 3G support

SATA 3G is faster on paper, but real world shows otherwise. No single hard drive can supply non burst speeds at 150MB/sec or 300MB/sec. Instead they are around 50-70MB/sec. Think of it as ATA100 vs. ATA133 but you get a small cable, hot swap, and maybe some NCQ.

This is all in laymens terms so you may be able to search for a more descriptive answer.

So they lied on the specs and it only 1.5?

Sorry that was a typo....it's 3G

ahh np. Then why didn't they work when I pulled the jumpers to run sata2? It just didn't detect the array and got boot disc failure. I disabled raid in the bios to see if the drives were detected by themselves. still nothing.

I have a 7200.10 320GB that is in native 3G mode (jumper removed) for my OS drive on SATA Port 3 and a 7200.8 250GB for my backup drive that is native SATA 1.5G on port 4 on my DFI NF4 Ultra-D.

What bios do you have on your board? I am using NF4LD329. Try one drive at a time on ports 1-4 to see if they show up in the bios.
