And?

The more I think about it, the more I come to the conclusion that
raid-10 is a bad idea for (a) minimising writes (and wear), and (b) for
safeguarding your data.

Yes it does have advantages, and yes I plan to put a raid-10 array on my
new system, but if reducing wear or protecting data are your priorities,
raid-10 is the wrong choice.

Cheers,
Wol
