Perhaps I am wrong but I feel that my question didn't receive an answer

So, let me rephrase my question:
Which one is better, RAID devices created on top of partitions or
partitions created on top of RAID devices?
With software raid you create partitions on the disk, then combine them
into md devices. With hardware raid the controller usually combines
drives into arrays which you can subdivide into volumes that linux will
see as a disk.
By "better" I mean under the aspects of data security, performance and
ability to recover from a disk crash.
I'm not sure there is an answer to that. You just need to understand
the procedure to replace a failed drive.

filesystem. I hope that more experienced and knowledgeable users here
will be able to give me some precious advice.
I have 2 120GB SATA disks on which to install the OS. I want to create
the following partitions:
/boot
/
/tmp
/var
/home
/swap
Two options are now present to me:
- Create a single RAID 1 device with both entire disks and then
partition on top
- Create several RAID devices, one for each partition (md0, md1, md2
and so forth)
Which one would be better from the points of view of performance,
security and data recoverability?
The latter is the way the installer will let you do it.
