Summary: Bought this over 2 months ago, the setup was very easy. Lots of options, very fast and reliable NAS. I am running it as a media server going to multiple devices, as a backup for all my data and as a ftp server.
Summary: I got the 8TB as was looking for a method of backing up my photographic collection that has >100k images of between 8 and 50MB each. After reading the instructions online a number of times I eventually got it running on Raid 5 giving me 6TB of usable storage with the knowledge the losing one hard drive would not lose my data. One of the disks sometimes fails to initialize, but pulling out and pushing back in again fixes that.
Summary: On installing I noticed that it was quite loud, really loud! This turned out to be one of the bays which was rattling. I stuck a piece of card between bay 1 & 2 which resolved the issue and though not ideal, it didn't warrant me returning the NAS. To give you an idea of the noise, the NAS was housed in a cupboard two rooms from my bedroom and I could hear it from there prior to inserting the card!
Summary: I wanted an easy way to back up data, music, video etc and being sceptical I thought multiple back ups was the way to go. I already had about 2Tb of data on various other drives (some backing each other up) and wanted somewhere to centralise everything. Probably not what the system was designed for but hey.... it works for me.
Summary: I would no recommend it to anyone. The CDROm provided does not contain the correct installation program. The quick setup is wrong, I had to contact support in order to get this working. It took me 4 attempts to get it working It goes to sleep somehow and I have not figured out how to wake it up. I do not recommend it to anyone.
OK on it's own but useless with another NAS - and BEWARE FIRMWARE UPGRADES
31 August 2013
Summary: I have had one of these devices for a couple of years and found it reliable until a firmware upgrade arrived which trashed it. At this point I realised that all the redundant drives in the world weren't going to help this problem! Fortunately I had made recent backups. I factory reset the NAS - at which point it told me that I had a bad hard drive. I didn't, it tested perfectly and I spent 3 days rebuilding and restoring.
Summary: Replaces a Quad-Core Windows 2000 AD-Server. I also have SheevaPlug computer which used to have a bunch of hard drives attached that was configured over SSH but the QNAP is worth the extra money for the software. All configured through the web browser and very simple to setup. I was using the latest 4.0.2 firmware with 4x1.5TB in RAID-5 and really was just plug and play. Also the power consumption with the Marvell ARM-based chips is a lot less than the Intel I was using.
