3 Drives in Raid 0 = better than 2?

  1. Right now I have 3 sata 2 drives setup in an "AMD 3 + 0" array in my Biostar TA790GX3 A2+. What I am wondering is is this setup performing better than 2 drives in a raid 0, or am I just wasting the extra drive. On an unrelated side note, my burst speed is around 320mb/s, and my sustained transfer rate is around 145mb/s using HD Tach 3.0.

    Well - is the drive size showing up as 3 times the size or 2? Also, did you mean 320mb or 320MB? There is a big difference - and if you meant 320mb then that's not very fast at all. If you meant 320MB and you are showing a size equal to the 3 drives combined then you are most likely getting the performance increase of RAID 0 with 3 spindles.

    Just be aware that if any one of those drives dies all of your data is gone.

    the size of the drives is 250gb x 3 = 750gb, so i am getting that, and i meant whatever mb or MB is equal or greater to the best SCSI burst rate.
