Summary: Does what it says with loads of features. Spindown issues are related to the drives you put in it. Note; most Seagate 7200.11 drives have firmware issues and this batch have huge amounts of DOA's esp the 1.5Tbs - check newegg comments. Western Digital standard drives are not RAID compatible so fork out for the RE versions if you want them to play nice.
Pros: Aesthetic. Solid.
Cons: Give me more throughput for RAID1. Put in a wireless adapter.
Summary: works well as advertised. A bit slow over FastE, mirrored drives. Setup was painless got me working in less than 5 mins (minus time it took to initialize my HD's No difference between Pro and Non-Pro versions, I just flash the firmware and have a Pro.
Pros: Excellent feature set Large Community QPKG enables installation of many third party software. Stays cool even after sustained writes of several hours.
Cons: Full featured but still pricey. No eSata connection in the back No usb storage option to directly connect to a PC. If you install the SABnzbd software, be prepared to have the cpu pinned on this NAS as long as it is running in the background
Summary: Just bought a TS-109 Pro and you have to use the included app to "initialise" it. Unfortunately the software just won't work for me and it seems to be quite common from the forums. QNAP support are of no help as well, they simply suggest using a different computer. By the way its not possible to set it up from a Linux PC, even though they claim full Linux support.
Summary: I recently got one of these and I already regret it. It seems QNAP is focusing on adding new features and fancy stuff, and leaving core NAS bugs unsolved. My main complaint is creating a backup of the NAS. I tried remote replication and copy to USB disk, and both are horribly SLOW and fail in the end. Also, the disk spindown feature does not work at all! I'd suggest going for a brand that doesn't have all the fancy stuff but functions correctly as NAS.
Pros: - nice design - good build quality
Cons: - buggy firmware: backup to USB not working - buggy firmware: disk spindown not working - noisy and hard to tweak noise down - expensive! - slow support
