I remember reading some where when we implemented the SAN, if you have SAN always use basic disks, not dynamic. HTH.

Is one better than the other? If so, why? I can't seem to find any info on using dynamic disks with Exchange(except that it won't work for the shared storage on a cluster). Any info would be great. Thanks alot
