15 * 250ms == 3.75 seconds.
Since SPI still really isn't defined to be hotpluggable, 3.75 seconds per bus
doesn't seem that bad.
It also depends on your environment. If this is an open bus connection, the
250ms is still desirable. If it's your own internal drives, set it to
I'm not sure the QAS stuff coming down is now what you're looking for tho.
