hi, this is not really postgresql specific, but any help is appreciated. i have read more spindles the better it is for IO performance. suppose i have 8 drives , should a stripe (raid0) be created on 2 mirrors (raid1) of 4 drives each OR should a stripe on 4 mirrors of 2 drives each be created ? also does single channel or dual channel controllers makes lot of difference in raid10 performance ? regds mallah.
