Raid scaling and write speeds.

post #1 of 3
Thread Starter 
My friend is getting his computer next week, and it's coming with two 750GB drives. He also ordered today a Black Magic Intensity Pro, a HD capture card. The thing needs 105MB\\s (sustained) write speeds for uncompressed video.

What I'm wondering is, is the onboard Raid controller on his motherboard (some G33 chipset with a ICHR9 southbridge) going to be able to raid his two 750GB drives, and will the sustained write speeds be enough?

I know the drives should get at least 70MB\\s write speeds, and two of them in Raid0 should scale that to around 140MB\\s, which should be more than enough. Right?

It will be cutting it close with the high latency of onboard RAID sometimes (Intel RAID tends to be rather good though)

You should be fine

Can't be worse than my Windows Software Raid of my 80GB IDE drives.

Thanks.
