I get the same result no matter which drive I test first, but I'm aware that 
hdparm is not the best tool for this sort of thing, probably bonnie++ or the 
like would be better. It's the ultimate performance of the entire filesystem 
that really matters, not just a portion of it, which is what the RAID array 
by itself is.

But I don't want to spend too much time on the matter, I know the RAID array 
will be faster than a single drive, and there's not much I can do to change 
its performance anyway (I could toy with the RAID parameters, filesystem 
parameters etc. I guess), but the system is fast enough and works well, so I 
leave it alone.
