Pros: I'm impressed how this NAS works with VMware. I have 10 VM running on the unit. The iSCSI is easy two config and interacts with vCenter with no issues. I have a full blown VMware hand on lab. I have both NICs which increase the amount of data this guy can handle.
Cons: Non so far. The unit has done more than I expected.
Pros: I got this new TS-469-PRO few weeks ago, this is a very nice solid machine. Easy to set up and deploy. The performance is impressive as it has a slightly faster atom processor (2.13GHz) then the ts-659.
Cons: So far it is running pretty good. This device does everything it was expected to do. Will try to update my review/rating if something changes with the product or support.
Summary: I have owned this Qnap 469 Pro for a week now and I am absolutely loving the new QTS 4.0 user interface and the features it has to offer. I currently have it set up with 4 3TB Western Digital Red NAS Hard drives which run cool and give great performance. I also decided to add Kingston 2GB of RAM which is easily installed and will give me extra performance and boosted the total to 3GB.
Summary: You get what you have paid for... The QNAP TS-469 Pro is one of the fastest NAS servers on the market. Low power consumption, very quiet, very fast and of course very reliable. Good Support and great community It's my second Qnap Nas and it will be not my last.
