If you take into account performance, maintenance and having disk not
failing into 3 months the price is not just 2x60 €.

A professional sata disk is more around 100€.

Saying that, the global size Mageia will need is more around 2 or 3 Tera
if you add BS, SVN, Mirrors, users home, etc...

Obiouvsly, managing such size is a bit more complex: you'll need RAID5
or RAID6, 4 to 6 disks and a computer with enough disk slot.

We cannot manage our server like a desktop if we do not want to be face
to problem later !

On mirror size the problem is bigger, you have to permanently check you
have enough disk space and adding 1TB to the current system is not just
adding a 60€ disk.

You can have a look to the picture at bottom of the distrib-coffee web
page to understand what I mean:

Each array cost around 1500€, but none of them have lost data yet since
it get installed (5 years ago).

Regards.
