Is it possible to make the drives turn slower ? To make the heads move slower ?
That would be my dream. No more heat, a 10mA consumption, no more noise...
If only... for a lot of the things I do, all I need is massive storage
capacity, not massive speed (I run crypto on the entire raid

you seem to be assuming that the drives have a lifespan measured in
hours-spinning. that's not at all clear. for instance, drives
are typically rated 40-50K start-stop cycles, which is ~40/day
over a 3-year service life.
you clearly do not want to auto-spindown unless you
I recently extended my raid array with a 9th drive, and I find that the
300 watt PSU I use is insufficient to start the system. What happens is
that I activate the machine, the machine starts powering up for 3
seconds orso (spinning all the hard drives up about half way) then power
cuts out.

Most problematic case so far, which I described numerous times (like,
why linux raid isn't Raid really, why it can be worse than plain
disk) is when, after single sector read failure, md kicks the whole
disk off the array, and when you start resync

They seem to suggest RAID 0 is faster for reading than RAID 1, and I
can't figure out why.
with R0, streaming from two disks involves no seeks;
with R1, a single stream will have to read, say 0-64K from the first
disk,
and 64-128K from the second. these
