    Really nice review Steven. :)

    That's some impressive results, even connected to a 1GB Ethernet network.
  2. What switch did you use to test the 10ge throughput? I have been looking for a decent 10 gig ethernet switch and they are all $10k and above.
  3. I would like to ask about RAID 5 and RAID 0. RAID 5 is usually on par with RAID 0 during reads, but on writes there should be a significant slowdown. Now, when using enterprise RAID cards that isn't the case because the parity is calculated on a chip dedicated to this. I assume the Synology is using linux software RAID 5 - no dedicated card - so why is it so fast? Perhaps the processor is totally dedicated to this and is up to the task?

    Based on most/all previous testing I've seen on RAID 5 I would basically never implement linux software RAID5 for critical storage/applications, but would have no problems doing it based on the numbers here!
  4. Prices for 10G switches drops last year.
    For example, Cisco SG500X with 4 10G ports cost around $1000.
    Equal Zyxel switch cost even less.
