Thank you everyone for you insights and comments.

I made a post of how I proceeded here:
http://blog.henyo.com/2012/03/cheap-and-safe-file-storage-on-linux.html

In summary, I did some benchmarks with bonnie++ using different raid
levels(5,10n2,10f2,10o2) using different chunks(64,128,256,512,1024)
using different file systems(xfs,ext4) and different settings for each
file system.

I decided to go with ext4 because I wanted to make use of the
data=journal option which IMHO is safer albeit slower.
