Perhaps where the spare may be used for any of several pools, whichever has a failure first. Not relevant to this case.. In this case, if the drive is warm, it might as well be live. My point was that, even as a cold spare it is worth something, and that the sata port may be worth more, since the OP is more interested in performance than extra redundancy. -- Dan.
