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.
- Use RAID6 instead of RAID5. You'll lose a little space, but you'll
gain quite some redundancy.
- 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.
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.
