Raid 0: Overall performance?

[Zasboy]

Hi,

Question. I got 4 harddrives which consist of a 40gig, 100gig, and two 120gigs. The 40gig and 100gig are using the onboard IDE controller while the two 120gigs are using an IDE controller card. The 40gig harddrive is my OS harddrive plus other applications, and the rest are for storage. So, I was wondering if I did a RAID 0 on my two 120gigs, will I get any performance boost? All I'm using it for is just storage. Maybe I'll do some encoding and playing movies off of them, but right now, it's just storage. But if I just RAID those two 120gigs, it wouldn't matter because the rest of my harddrives(40gig and 100gig) are using the onboard IDE controller, so overall performance wouldn't change much would it?

-Thanks

Nope, video encoding and playback won't benefit at all from RAID 0. They require a meager throughput of only a couple of MB/s, which is why DVD and even HD content can be played over 100 Mbps networks without trouble. On the other hand, RAID 0 doubles the amount of data loss if a drive in the array were to crash. The data on both drives would be lost, since the RAID 0 configuration spans data chunks across both drives constantly.
