I'm in Serbia. I tried several web sites of more known dealers, but it's
possible that they don't have everything listed there on their web
sites. If my boss approve buying RAID card, I'll call them to see if
they have it or if they can order one.

I meant "some" as in it's something. I'm aware that they are not equal.

I didn't till 30 minutes ago. :) I just installed it for exercise if
nothing else. Had a problem with booting. 

"Unable to install GRUB in /dev/sda
Executing 'grub-intall /dev/sda' failed.
This is a fatal error."

After creating 1MB partition at the beginning of every drive with
"reserved for boot bios" it worked (AHCI in BIOS). 


Anyhow, this is output of "cat /proc/mdstat":
Personalities : [raid1] [raid10] 
md1 : active raid10 sda3[0] sdd2[3] sdc2[2] sdb3[1]
      5859288064 blocks super 1.2 512K chunks 2 near-copies [4/4] [UUUU]

I'm not sure what is being copied on freshly installed system.
