Well, if I did not do heavy searching (which is basically random reads) like this then the difference really would be small. It all depends on the user... However the agility is definitely very rough around the edges. If you write to it too much at once (like 25GB) the sequential writes go to 7MB/s. No joke, 7. I first noticed this when I was imaging my X25-E onto the agility. Started off at a cool 100+mb/s and then kept dropping all the way down to 7.
