Re: RAID5 or RAID50 for database?

And stick with md-raid 10 (also known as software raid) because it is
much more intelligently designed than any
closed-source-embedded-raid-controller.

This was valid until...quite a few years ago.


Nowadays hardware raid frightens me because of the need to have spare
raid-controllers for every hardware-raid-configuration I have. They
are neither interchangable nor easily recoverable.

You seem to have been living under a rock for the last half decade.


md-raid 10 can be established with any number of disks (at least 3 but
better check with google)

Hmm, I think your advice must be taken with a grain of salt. Have you actually tried to do what you suggest? In any case, I will give you the benefit of the doubt that you just did a typo.
