Raptor vs. Raid Level 0

[LarryBoy]

I'm wanting to set up a desktop computer primarily for video editing and DVD autoring. What does everyone here think would provide the best performance: a SATA Western Digital Raptor 10,000 RPM drive or 2 ATA 7,200RPM drives configured in a level 0 raid setup?

Any comments would be appreciated.

raptors are faster than a 7200 raid 0 array. They just are. although, a 7200 raid 0 array isn't A LOT slower, and its definately way more bang for your buck.

If you're looking for speed, raptor(s) would be faster (or two raptors in raid 0 )

But if you're looking for budget, or space (if you're doing video, you'll need the space) than 7200 rpms wouldn't be a bad choice either.

oh, nevermind, disregard what i just said. :claps:

I automatically think everyone uses their computers for gaming. haha (silly young adults!)

Anyway, now that i Reread your question, i'd DEFINATLEY go for the Raid 0 Array. Raid 0 shines in big projects such as video editing.

Also, there have been a million 2 7200 v 1 raptor tests on the web. All with mixed results. However, one thing is agreed upon, for fragmented drives (where the data isn't stored consecutively [ex. your data is 123456. on a raptop its stored 123 in one spot, then 456 in another spot, on a raid array, you have 135 on one drive, 246 on the other]) The raid array outperforms any single drive. This is because the single drive would be forced to make two separate seeks for the data, (each about 8ms), while the raid array makes only one seek for both pieces (about 8ms) + RAID overhead (negligble).

If you would defrag your raptop each time before you used it, this wouldn't be a problem, but in a real world situation, you wouldn't defrag every time.

If i didn't feel ilke lighting my wallet on fire, i'd go with the RAID array.

HTH

Thanks!

Thanks for your input.

I'm realling leaning toward the Raid level 0 setup as it seems it will give me best bang for the buck.

I know my brother put together a DVD for my parents 50th wedding anniversary that lasted about an hour. He said it took about 12 hours for his moderate computer to render the video before burning to DVD. I want to do all I can to improve on that performance.
