I got this about a year ago for use as a backup for my regular 8 disk QNAP 853Pro NAS. Basically, just copying the data from the main NAS to this one. I wanted to keep it in the same brand just for compatibly sake, but that isn't required.
After using it for a year, the TS420 has been pretty good. I did have one major hickup where a disk failed in the RAID5 array last week, and while rebuilding, the power went out to the house and the TS420 shut off. When it did so, the array was toast and wouldn't work. Tried everything except for calling for support. All 4 drives showed up, but were listed as single drives. Went though all the documentation, which has lots of ideas, but none of them worked. After around a day, I just wiped the drives and had the NAS set up again as a RAID5 and pushed the data down again from my main NAS over rsync. Oh well, no big loss for me besides a week of copying the data back. Slightly disconcerting though, as that implies it could happen...
Great NAS. This is my second QNAP. I also have a TS869-pro that works well. This one has four 2TB drives (WD green) and it works well enough for my needs. It is merely a dumping ground for a backup of backups. The NAS-to-NAS copy feature works well between two QNAPs which replicates about 4.5TB of data regularly. I used to have a Synology DS411j and replaced it with this. I'd say the QNAP is a little faster, but then again it is a newer model than the Synology was, so that's probably why.
Bottom line: if you can afford the big QNAP, get the bigger one as it is faster. But if you can only afford this unit, it will perform well enough in most small business/home networks.
I got this used for a good price. It has been very reliable: I have only had to reboot it when it installed updates to the OS. The NAS was easy to set up, and the web interface is complete and well-designed. It runs fairly cool with two drives inside, and since it has two network interfaces, you could even set it up as a gateway/firewall for your LAN if you really wanted. I did have a couple of questions about how to set up some of the provided web applications, but the members on QNAP support forum were able to answer my questions without any trouble.
