Software raid VS hardware raid

[Artem Kuchin]

Hello!

I have to made a decision on choosing a dedicated server.
The problem i see is that while i can find very affordable and good 
options they do not
provide hardware raid or even if they do it is not the best hardware for 
freebsd.
The server base conf is 8core 32gb ram 2.8+ ghz.
So, maybe someone has personal experience with both worlds and can tell 
if it
really matters in such configuration if i go for software raid. What are 
the benefits
and what are the negatives of software raid? How much is the performance 
penalty?
I am planning to use mirror configuration of two SATA 7200rpm 2TB disks. 
Nothing fancy.
File system planned is UFS with journaling.
