    I Dont get this…our onboard raid is fast enough for uncompressed

    Posted by Miles Blow on January 30, 2007 at 12:57 pm

    Hi

    We have been looking at getting the caldigit s2vrhd for speed but it looks like the nvidia raid built into our motherboard (asus a8n32-deluxe)is faster. I just did a decklink speed test on it.

    Data read rate in mb/s= 230.1
    Disk write rate in mb/s 243.5

    Its 4 x 300gb seagate sata2 drives. The other thing is its half full. Its got 500gb of footage in there all ready. Could this make it give inacurate speed readings?…if anyrthing I thought it would have been slower.

    Do you think this is a reliable test. If so maybe we should just get bigger drives for it. what do you recon?

    We have got them stripped at the moment but it says in the manual that it can do strip mirror ..I wonder what data rates it can do in that mode.

    If the macs had an onboard raid this fast(and room for the drives) would everyone just use that?

    Thanks for any feedback
    ps…. new 5.9.1 drivers are out

    Have you tried to ingest anything yet?

    I am looking at the new Areca ARC-1231ML raid controller with the IOP341 for 12 drives in raid 6… Sustained 600-900 write speed for post production.

    I am however planing on a 2 drive raid 0 boot array off of a new 680i mb. It would be great to use raid o on the other 4 on-board ports for a raid 0 for quick UC SD if it is fast enough. I hope this will not melt he southbridge on the MB 🙂

    Hi Joe
    We are actually rendering hd from big 3k still images(stopmotion animation)So we actually havent ever captured hd.

    Can you recomend any sites that talk about the areca card/performace ….sounds like its got some power?

    I just captured a bunch of 1080i footage with 5 sata drives software striped in XP (raid 0), no problems. The drives are connected to the motherboard’s built in sata ports. Most of my storage is on a highpoint raid 5 card, that works too. Just make sure your audio capture folder is on another drive so your raid won’t have to seek so much for simultaneous writes.

    Miles and Jules, Here is a link to burst test with 12 SATA II drives

    There are many reviews of Areca controllers out there but the IO341 is fairly new so there is not much that I have found for real world tests.
