Excerpt: Pros: Quality workmanship and appearance. If the software has what you need, it is quite flashy and easy to use. Wiki, Forum and How-To guides available. You can build QPKGs to add-in features not in the base software. Unit comes with both the Emulex and Intel mounting brackets. Screws and cables provided. Relatively small size and low power usage. Two large quiet fans pull a good volume of air for cooling. USB 3.0 ports and SATA 6Gbit hot-swap drive bays.
Summary: I initially had this setup for RAID1, with two Hitachi HDS724040ALE640 4TB drives. Since the rest of my drives are in back-order. I set this up in production, thinking I can expand later. Sure enough when the rest of my drives came; I was able to migrate from RAID1 to RAID 5, with a total of five drives. These are 4TB drives; the completion time was almost 20 hours. All of my iSCSI mounts, NFS share, was just temporarily offline, but they mounted automatically when done.
Summary: I live far away in middle east, and I find it important to mention that QNAP factory packing is more than excellent. Excellent product, easy to setup, and the sound of fan is not bad at all if the server is placed away from your screen. The two fans keeps running all the time, unless you do play with their running operation, which I didn't need to do. No heat at all coming out of the case.
Summary: I complain about the price because its relevant to me, however if you fill the box full of enterprise drives and a 10 gigabit interface, it will keep up with SAN systems costing millions of dollars.
Pros: Easy to set up and full of functionality. This SAN/NAS has been very reliable. This box is extremely high performance, especially when you put a 10 gigabit adapter in it. The box is VMware certified and plays well with ESX5.
Cons: I wish it was about 10% cheaper. Also, DO NOT try and use it for the surveillance station option. That functionality is worthless.
