also @ TechSpot: OCZ Vertex 450 Review
Hoping to drive small and medium business sales, NAS-makers have been pushing to deliver enterprise features such as cloud storage, virtualization support, automated backup software and iSCSI support. There's also been an effort to include technologies such as Link Aggregation, which can increase network bandwidth when dealing with multiple users and also provides redundancy in case one of the links fails.
First seen over a decade ago, 10GbE is not a new technology, but it's been largely reserved for pricey enterprise devices. It's ten times faster than Gigabit Ethernet and only supports full duplex point to point links, which are generally connected by network switches, so 10GbE hubs don't exist.

The 10GbE standard is slowly gaining momentum. With that in mind, we're checking out two new high-end SMB NAS devices: the QNAP TS-879 Pro, which costs $2,200 without its optional 10GbE network card, and the $3,500 Synology DS3612xs.

Really nice review Steven.
That's some impressive results, even connected to a 1GB Ethernet network.

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.

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!
