If there is a read error on a disk, the rest of the array gets spun up to calculate what should be there and write that result to the erroring hard drive location. If that write fails, the system will red ball the drive. So, one of the critical array protection features requires that the PSU can handle simultaneous spinups. I would much rather the system not start at all rather than start staggered, and run out of power when a disk read fails. If you are scared that your PSU is on the edge power wise, you need to upgrade the PSU. Very few things can cause as much havoc and data corruption and possible physical damage than a failing PSU.
