It is well known that repeatedly spinning a drive down/up is absolutely the
worst possible thing you can do to it, from a long term reliability standpoint.
So my personal suggestion would be to reconsider if you really want this. The
power consumption from 7 spinning drives with no access should be no higher
than 60-70 watt; IMHO saving that amount, is not something that's worth risking
your disks and data for.
