    Are two ATA100 drives set up as raid 0 faster than a single raptor drive? I got a used Intel 845PEBT2 board and want to use it for video work. If I ever decide to go with 2 sata drives as raid 0, How much faster are 2 raptors compared to 2 seagate sata drives? Big difference?

    Well, I dont know if the RAID 0 ATA 100 drives are faster than a raptor, but SATA segate drives have an 8.5ms seek time where as raptors have a 5.2ms. I dont know how much real world performance that would yield though. Someone else more savvy in HDD's than I will probably answer, : peace2: Mista K6

    I think, and this is just my opnion, that the ATA 100 drives in RAID would be just a tad better. Heres my train of thought.

    #1: SATA is limited to 133mhz right now because PCI buses can only support up to 133mhz, even if the controller is right on the board.

    #2: RAID is a big performance boost, so depending on just how slow the ATA drives are, RAID 0 might make up the difference.

    #3 The two ATA drives are probably gonna be alot cheaper, and money is everything when it comes to deciding stuff for me.

    #4: Unless you're doing Hollywood Movie editing or have a 100 GB Database to run, your hard drive speed might only mean a few more seconds on load times in Half-Life 2. Two Raptors in RAID 0 just arent worth the money for us enthusiasts at the moment.

    Yep,2 raptors are certainly not a cheap thing.

    <<#1: SATA is limited to 133mhz right now because PCI buses can only support up to 133mhz, even if the controller is right on the board.>>

    If this is the case, then I would tend to believe that 2 ATA133 drives set to raid 0 would be equal if not faster than 2 raptors set as raid 0? I hear so much talk about spindle speed. 10,000 rpm verses 7200 rpm and that the 10,000 will beat the 7200. If its only a few seconds, I can live with the extra few seconds. Thanks folks.

    That's the main issue^^. My friend was gonna put a RAID 0 raptor set up in his new comp, I said, what's the point? At $115 a pop those are expensive drives, and unless you constantly do video editing etc., you wont notice the performance (he's a gamer). So, 60GB SATA Maxtor's are $75 a piece, he saved $80, and still will have awesome performance. Sometimes you have to know where to draw the line :smokin: . : peace2: Mista K6

    EDIT: could be wrong, but I thought PCI is 33mhz (and AGP is 66mhz)

    By themselves, the Raptors make good drives for AV work. However, as soon as you put anything in RAID, it's going to be as good, if not better. Plus, if you're doing video work, you really need storage space as well as speed.

    Personally, I'd go for either an IDE RAID or SATA RAID, with a couple 8mb cache drives. I've got 2 x 120GB Maxtor SATA drives in RAID, and I've filled up and still use about 50GB in video and editing tools. I can't fault the speed, as it happy captures video from any source without loss (ATI All-in-Wonder capture or Firewire capture).

    Looks like its going to be ATA raid 0 for me. :thumb:
