Multiple spindles *does* increase the number of hardware failures your system
will have. Using redundant RAID makes your system tolerant of hardware
failures. Balancing these can be complex. :)
Slower, though ... is a bit of a strange claim. Not because it is false, but
because the answer is complex: you can, for example, double read speed and
halve write speed, using a two disk RAID 1 array ... in the ideal case.
Is that slower, or faster, or both?
