Striped Raid Question

    Hi All,

    I'm thinking of investing in two identical SATA drives which I hope to set up as a striped array. Logically, I would think that having data equally split across 2 drives should give me a 100% speed increase (ie. twice as fast) at loading data. I've never used one of these arrays, so I wonder what type of performance increase I could expect? (I have 4gb ram)

    Also, would Ghost or other such software be able to take all the data from my current C: drive and transplant it neatly onto the new striped array, and do it in the correct way?

    Thanks,
    K.

    Ive done it before and the performance boost isnt exactly huge. It's definetly not 100% Just buy a Velicoraptor HDD if you want an ultra fast drive.:D

    I put my two 150Gb raptors in Raid 0 using the Nvidia software and the results were about a 5 - 10% increase in performance.
    Apparantly you can get better results if you use a dedicated controller card.
    I have never used one of these but perhaps someone on here can tell you of their experiences, the software RAID is not worth it.

    Avoid the Raptors. Heres my 2x36Gb Raptors in Raid 0 compared to a 1Tb Samsung f1 sata

    Performance boost is about 15% over a single hd, not worth it IMO, (I've these Raptors 3 yrs now tho). Just opt for a single F1 sata, these are the ones with the 32MB cache

    Excellent info, thanks for the heads up. I'm gonna order a 1tb F1 right now! :)
