So I bought one. 4 TB for the everyday low price of 10 grand. She is a beauty. I have two Raid 5's on either controller each connected as DAS on two different servers. Both are clocking in around 87 MB/s. I would have though it would have been higher. I was hoping a fellow Xserver Raid owner could give me their performance numbers or some who knows what they should be could chime in as well.
