Summary: It was touch and go with this NAS until QNAP released a stable update to the firmware. All good now. This NAS is underpowered for all the features it has/things you could do with it. Solid NAS if you keep the setup simple.
Pros: The device has a lot of flexibility. Had it configured in raid 1 with two seagate drives, and it was happily running transmission, couchpotato, sickbeard, and sabnzbd for the past 22 months
Cons: The issues with this unit are after a drive failure. Basic approach should be: 1 - Remove bad drive 2 - Add new drive 3 - RAID rebuilds automatically Did that happen? Of course not. Where the product documentation says it will happen automatically, that never occurred. I ended up having to do the steps of the rebuild manually, and even then they were not really successful. The support from QNAP is questionable and limited to forum posts that do not always address the ...
Summary: UPDATE to below: After a recent firmware update, the unit is performing much better. I do not have it disconnecting from my MAC anymore. MAC still requires you to press continue to accept the self signed ssl certificate, but seems to allow access via the finder as a server. Qsync actually works quite well. It has been updated several times - they are clearly working on Qsync. If it stays this way for a while, I will move the review up to 4 stars.
Summary: Installing the drives and getting my data restored to it wasn't much of a problem using the web-based utility. I still haven't found out how to actually use this as a Network Area Storage device. I'm not interested in using it as a personal cloud or as a multi-media or music player. I just want to be able to easily access it from any computer on my network, regardless of operating system by mapping a drive or mounting a volume.
Summary: It's probably the cheapest NAS that you can buy that supports RAID 1. Pros: 1) Easy to setup and configure 2) It works 3) It's cheap 4) It's great if all you want to do is use it as a pure network drive Cons: 1) The software sucks really bad. 2) You can't disable thumbnail generation permanently. When you browse a folder with a bunch of videos the first time, ffmpeg will spend hours generating thumbnails, and you won't be able to use the NAS during this time.
Summary: A ton of features are included with this device. You can access storage by almost any storage / file sharing protocol. Sorry, no fiber. The big downside is the weak ARM processor. For all the ways you can store and access files, you're going to be waiting for it to happen. Also, don't even think about streaming movies from this thing. The low powered CPU just won't cut it.
Summary: I have been using this NAS with 2 hard drives configured in raid 1 without problem for almost a year. It's a little bit noisy, but it's OK. The management interface is very nice, with many adjustable parameters. I also enjoyed accessing my NAS while on travel through the internet. The only limitation I found is that you cannot wake the NAS up from the LAN, which forces you to plan very long power-on periods to be sure that the NAS will be available when you need it, and...
Summary: I have had this for about three years and the last software update finally made it usable.i use it for storing photos and music and my amplifier connects very easily via the pioneer app on my notebook.
