Cranking up 10K RPM drives will require substantial power. A real crude
yardstick is that the 1.0 inch high drives will take less to spin-up than
the 1.5 inch high drives (more platters=more mass, inertia)

Your specifics will be different than others, so nobody can give you a
"yes it will" or "no it won't answer". On the dual (redundant) power
supply enclosures I work with, the adapter will only issue "start"
commands to 4 drives at a time to reduce the peak loads. Naturally,
the drives are config'd not to auto-start at powerup.
