QNAP TS-259 Pro Conclusion

Although the rating and final score mentioned in this conclusion are made to be as objective as possible, please be advised that every author perceives these factors differently at various points in time. While we each do our best to ensure that all aspects of the product are considered, there are often times unforeseen market conditions and manufacturer changes which occur after publication that could render our rating obsolete. Please do not base any purchase solely on our conclusion, as it represents our product rating for the sample received which may differ from retail versions.

The performance of the QNAP TS-259 Pro NAS server compares very favorably against similar network storage products. Based on the test results with the single disk configuration, the QNAP TS-259 Pro offers excellent performance when fetching small to large files. It always scored in the top five, against some heady competition. The beefed up Intel Atom D510 1.66GHz Dual-Core processor and 1GB DDR2 DRAM made all the difference in performance, compared to the Marvell-based T-419P. The best read performance was 59 MB/s, and the best write speed was 44.8 MB/s. Both of these speeds were recorded with 1GB files, but the 10GB results were within tenths of a MB/s.

The smaller, two-bay form factor of the QNAP TS-259 pretty much precludes the use of a display on the front of the unit. Status LEDs are provided for activity on: HDD1, HDD2, LAN, and eSATA. The exposed portion of the drive trays are nicely finished and blend well with the remainder of the front panel. Three different shades and textures of black can look busy if arranged poorly, but this NAS looks the business. The side panels are titanium colored with a fine grained brush finish. The brighter finish adds a bit of elegance to the visual design, plus it doesn't show fingerprints, win-win. IMHO, it fits in perfectly with its intended environment, the small office or home office.


The construction quality of the TS-259 exceeds that of many computer-based appliances. The data center crews are all hardware junkies for the most part, and they like their gear to radiate superiority. QNAP takes the level of excellence that is required to win over that finicky community and applies it across the product line. Enjoy the trickle-down effect where you can, even if it's from the data centers on Wall St. and not the banks on Wall St.

The QNAP TS-259 Pro Turbo NAS network storage server is going to have tremendous appeal to a very tech-capable SOHO organization that can take full advantage of all the capabilities and functions it offers. For some businesses, that need all the benefits but aren't tech-savvy enough to exploit the full functionality without some hitches, utilizing a Value-Added-Reseller (VAR) to integrate, configure and test it in your environment is always an option. Especially if your company already has a relationship with one, it could reduce the potential for start-up headaches. I've focused almost entirely on functionality that's important in a business environment, but the support for home entertainment applications is also impressive, with support for UPnP/ DLNA Media Players as a simple example. Fortunately, these features are all a little easier to configure.

The QNAP TS-259 Pro Turbo NAS server may be less suited for the corporate Enterprise environment, but its size, performance and features certainly hit the SOHO market head-on. Two drive bays only allow for RAID-0 or RAID-1, and that may be all you need for the home office. Before we discuss the pricing in detail, remember that these systems are not discretionary items for most businesses, they are a necessary expense. The inevitable costs for not having a robust data management system in place are usually 10-100 times higher than any of the prices you will see in this paragraph. As of late April 2010 the TS-259 Pro model was listed at NewEgg for $599. Compared to the Marvell-based QNAP TS-419P which also sells for $599, the performance gains from the upgraded processor and memory get traded for a doubling of storage capacity and the ability to run RAID-5 configurations. If you need the wealth of features the entire Turbo NAS series provides and more storage space, the TS-459 Pro is the logical choice at $899. For storage-centric environments that need the absolute best, QNAP offers the TS-809 Pro which is available for $1700 without drives. Home users could feel more comfortable with the single-bay QNAP TS-119 for $300 for basic tasks.

Benchmark Reviews has tested all of these QNAP network storage solutions, and with the wide range of products they offer, anyone in need of a NAS server can find one to fit their current and future needs. The TS-259 Pro Turbo NAS server seems ideal for certain segments of the SOHO market. A few may need something simpler, and others may need more storage space, but the two-bay TS-259 hits the mark for a large portion of users.

No test with the network in "bonding" ?

# I did, but....BruceBruce 2010-05-04 07:15
I repeated the tests with IEEE 802.3ad Link Aggregation Control Protocol, using two Intel Gigabit CT Desktop Adapters in the test bench system. The problem with that test scenario and Teaming or Bonding or whatever you want to call it, is that the network speed stays exactly the same. The bandwidth is increased by widening the data path, not increasing the speed. I.e. it?s analogous to two fully loaded trucks driving the speed limit instead of one truck delivering your data. Yes, you get twice the data, but you get it in the same time frame, which is what our testing measures.

I think the way to test this feature is to have two or more transfers occurring at the same time. With one transfer already under way, another could be started and timed, and the speed of the second transfer should be relatively unaffected by the continued activity of the first one. Your thoughts, suggestions?

# 802.3ad is NOT your solutionscavenger 2012-11-30 12:01
YES this is it. Load balancing is made only on multiple file transfers.

If you can read french, I posted a lot about it on but the result is this one :
Conclusion is 802.3ad is ONLY failover. ABSOLUTELY NOT load balancing.
If you want to do what I dreamed of, choose on each side the Balance-SLB (or Balance-ALB) + round robin transmit load balancing method.
Then you will have a smooth repartition of the packets on each port, but you will notice a strong down bandwidth due to the fact that "Packet order is NOT guaranteed"
Load balancing for a one file transfer on many cables is just a dream... right now...
