If you can afford it I would prefer to use RAID10. You will loose half
of disk space but you will get really faster system. It depends what you
need / what you will use server for.

Do I have to consider anything before installation, because the disks
are very large?
I'm doing this kind of installation quite regularly. Here's my two cents.
1. Use RAID6 instead of RAID5. You'll lose a little space, but you'll
gain quite some redundancy.
2. The initial sync will be very (!) long, something like a day or two.
You can use your server during that time, but he'll not be very responsive.
3. Here's a neat little trick you can use to speed up the initial sync.
$ sudo echo 50000 > /proc/sys/dev/raid/speed_limit_min
I've written a detailed blog article about the kind of setup you want.
It's in French, but the Linux bits are universal.
