In disk option, where smart options, APM and AAM can be managed, it will be a nice feature to add the possibility of a Spin-Up tempo/delay.
Hard drive when they start/spin-up can consume very high current for a short time (2, 3 or even 4 times the normal duty/working current), and when you multiply by the number of disk in the array, you quickly arrive to significant peek power that can bring instability and push to build over-dimensioned power supply.
Adding a delay may allow to spread this peek current over a few second, with a fairly acceptable trade-off.
Just for example, a few 3,5" recent hard drives but also valid for 2,5"
