For what it's worth, I configured a T5220 this week with a 6 disk, three mirror zpool. (three top level mirror vdevs...).
Used only internal disks... When pushing to disk, I was seeing bursts of 70 odd MB/s per spindle, with all 6 spindles making the 70MB/s, so 350MB/s ish. Read performance was about the same for large files. (did not do anything with small files, though I expect that with the 2.5" SAS disks, it should be pretty good...). I was not seeing a consistent 70MB/s per spindle, which I put down the the fact that I was only using a single thread to generate the writes. (A single thread of an N2 is only so fast... Just think of what you could do with 64 of them ;) I'll be interested to see what the others have to say. :) Hope this helps. Nathan.
