The four-bay QNAP TS-469 Pro NAS server is somewhat of an upgrade to the previously reviewed
In the end, in comparison with the Synology DS412+, I found that the QNAP TS-469 Pro's somewhat better hardware doesn't justify its much higher price, especially considering it doesn't offer the level of robustness and forward thinking found in the DS412+'s user interface and features. And if the Synology is not exactly for novices, the QNAP TS-469 Pro is definitely not for the faint of heart. Advanced users will still be comfortable with it, however, thanks to the well-organized Linux-based operating system.
That said, the new QNAP TS-469 Pro still ranks as one of the best four-bay NAS servers on the market, and is worth its $830 street price. Personally, however, I don't see why you shouldn't instead get the $650 Synology DS412+, which offers a much better combination of features, performance, and ease of use.
For a multiple-bay NAS server, nothing beats the TS-469's hardware design. The server is housed in a rugged aluminum case that's both good-looking and practical. The four hard-drive bays are accessible from the front with removable drive trays. These trays can be removed or inserted into the bay without any tools and can be securely locked in their place to prevent accidental opening. The server comes with two (identical) keys, one of which is needed for both locking and opening the trays. This in itself is very well thought out since if you could lock the trays without using the key, you'd risk misplacing the keys and being unable to open the trays. The Synology DS412+ has a similar drive bay design but without the locking option.
As with the DS412+, you do need a screwdriver to attach the hard drives to the trays, which can handle both 2.5-inch (laptop) and 3.5-inch (desktop) standard SATA drives. The server supports hard drives of up to 4TB, effectively offering up to 16TB of storage space in RAID 0, or 12TB in RAID 5. For a four-bay NAS server, you really shouldn't use RAID 0 since the risk of losing data is too high. RAID 5 is probably the most popular in this case since it balances performance, storage space, and data integrity.
While Synology has its Hybrid RAID, which is similar to RAID 5 but also makes it possible to use of hard drives of different capacities or increase the RAID's total capacity without having to rebuild it from scratch, QNAP doesn't offer a special RAID configuration for its NAS servers. The TS-469, in my trials, did offer a way to expand the server's storage space without having to rebuild the RAID, however. You can do this when the hard drives are set up in RAID 5, RAID 1, RAID 6, or RAID 10, as long as you replace just one hard drive at a time, and don't use any hard drive larger than 4TB. Depending on the amount of data you already have on the server, it can take a long time, even tens of hours, for the replacement of one hard drive to be completed.
Like the TS-412, the TS-469 Pro has an array of LED lights on the front of the case that show the server's status. There's also a little LCD and there are two navigation buttons for scrolling through details about the server, such as its IP address and network name. In case of a serious error, such as network disconnection, the screen will also display a detailed error message, making it a handy feature.
Also on the front are a USB port and a one-touch Copy Button that helps quickly back up the entire content of an external storage device plugged into that USB port. On the back the server has another six USB ports, two of which are USB 3.0 ports, and two eSATA ports that can be used to extend its storage space or to host a printer. This is the area where the TS-469 Pro is clearly better than the Synology DS412+ since the Synology has only three USB ports, one eSATa port, and no Copy Button.
The QNAP TS-469 Pro also two Gigabit Ethernet ports, normal for a high-end NAS server. These ports can be used together for fail-safe or load-balancing purposes, and when used with a supported switch, can also increase the server's performance via Link Aggregation.
The review unit came with no storage. I installed four 1TB hard drives in it and then ran the QNAP Finder (bundled on an included CD) to launch the server's Web interface. The interface started with a wizard that walked me through the rest of the rest of the setup process. I chose a RAID 5 setup and was able to start using the server after about half an hour.
While I personally found this process easy enough, novice and home users will likely find it intimidating, as the included instructions are not written for laymen. Experienced users, on the other hand, might not need to read the instructions at all.
