• Cloud backup to Amazon S3, ElephantDrive, Symform
|• Lacks 10GbE option
• No eSATA
Last month, we reviewed QNAP’s x51 line of dual-core Bay Trail D Celeron NASes aimed at well-heeled Home and SOHO buyers. This time, we’re looking at the x53 Pro family intended for small-biz customers.
The TS-x53 Pro series comes in two, four, six and eight bay models. All share a common hardware platform with two versions. The two-bay TS-253 Pro uses a board with two Gigabit Ethernet and three USB 3.0 ports. The rest of the models use a different main board with four Gigabit Ethernet, three USB 2.0 and two USB 2.0 ports.
None of the x53 Pros have eSATA ports, as is evident in the view of the rear panels below. All four models have a single HDMI port and integrated IR MCE Remote compatible sensor. In keeping with many of QNAP’s other "Pro" offerings, all models have lockable drive trays and all except the two-bay have LCD status panels.

Key hardware features are compiled in the table below. Note there are two versions of each model; one with 2 GB of RAM and the other with 8 GB. If you don’t like QNAP’s RAM pricing, you can upgrade the RAM yourself.

I tried disassembling the TS-653 Pro sample to take the photos and identify components. I got all the way to getting the board free, but couldn’t get it untethered from its front panel connection to take clean photos. The board is different than the one I found in the TS-451. But, then again, the TS-x51 series uses a different board for its six and eight bay versions than for its two and four bay.
I guess QNAP didn’t make it easy to get the board free is because both SoDIMM RAM slots are easy to get to once you remove the cover.

Here’s a pretty crappy shot of the other side of the board. You can see the heatsinked CPU, Fintek F71869AD at the top center and PLX PEX8603 PCIe switches toward the right. Two of the Intel WGI210TA single-port Gigabit Ethernet controllers are on this side of the board and two can be seen on the left side of the board in the photo above.

Table 1: Key component summary and comparison
We equipped the TS-653 Pro review sample with four WD Re 3 TB (WD3000FYYZ) drives for testing. Power consumption measured 57 W with the 4 drives spun up and 20 W with them spun down. With only two drives inserted for the TS-253 Pro tests, power consumption dropped to 36 W with the drives spun up and 18 W with them spun down. Fan and drive noise could be classified as medium low, i.e. quietly audible in a quiet home office with four drives loaded and low with only two drives.
Performance – Summaries
4.1.1 Build 20141003 firmware was loaded on the TS-653 Pro sample (2 GB RAM version) for our standard NAS test process. Since all four models use the same processor, RAM and Ethernet components, all testing was done on the TS-653 Pro sample.
Results from tests using four drives configured in single RAID 0, 5 and 10 volumes were entered into the NAS charts for the TS-453 Pro, TS-653 Pro and TS-853 Pro listings. The TS-253 Pro tests used two drives in single RAID 0 and 1 volumes.
The 6 hr 45 min to completely build and resync 4 x 3 TB RAID 5 volume was significantly improved from the 17h 20m we measured with the TS-451. Unlike Thecus and Synology, QNAP does not offer the option to skip a bad block test, which can speed volume resync times significantly.
For reference, here is the Benchmark Summary for the four-bay and greater models…

These summaries don’t mean much by themselves. So we’ll dig down and compare to other products next.
Performance – Comparative
Whether you use Windows File Copy or NASPT File Copy benchmarks, the results show that all the x53 Pro models pretty much max out the capability of a single Gigabit Ethernet connection for RAID 5 writes. But so do their less-expensive dual-core Celeron x51 series equivalents, like the TS-451. On the other hand, RAID 5 read shows a more significant 10 MB/s gap between the TS-451 and TS-453 Pro.

Comparing two-drive RAID 1 performance tells a similar story, except with closer read results.

Using the NAS Ranker with no filtering shows the x53 Pro pack trailing Thecus’ i3-based N8850 Top Tower, Pentium G620-based N6850 Top Tower and Xeon-based N10850. The QNAP TS-653 Pro and TS-853 Pro look to be priced about $200 less than their Thecus compeition, however.
Comparing the six bay TS-653 Pro and Thecus N6850 shows a mix of pluses and minuses. The Thecus has about twice the performance for directory file copy writes and reads. But it comes in about the same for the mixed read/write benchmarks and is significantly slower for USB 3.0 attached backup.

If you’re trying to decide whether it’s worth it to pay more for the TS-453Pro vs. the TS-451, the Performance Summary Comparison below says it’s a difficult call. The 453 Pro does better than the 451 on some directory copy tests, but with smaller margin than the previous Thecus comparison. Everything else is pretty close.
QNAP TS-453 Pro, TS-451 Performance Summary Comparison
I know I say this a lot. But QNAP is known for having a lot of NASes to choose from, making buying decisions more difficult than they perhaps should be. I’ll reprise Craig’s price comparison table from his TS-251/451 review to boil it down. Keep in mind that all the x51 models come with 1 GB of RAM, while their x53 Pro equivalents come with 2 GB. Both families can be expanded to a maximum of 8 GB.

(all prices from Amazon on 11/05/14)
The six bay TS-653 Pro seems to be the pricing sweet spot, if you’re ok with spending about $1000 for a naked NAS. But $500 for a two-bay NAS is a pretty hard sell in my book, no matter how powerful it is.
As noted earlier, to get your money’s worth from a TS-x53, you’re going to need to use aggregated ports with multiple clients and / or load it up with RAM and run multiple VMs. But if you’re just looking to get the most of a single Gigabit Ethernet connection for large file transfers and want to buy QNAP, save yourself some dough and get a TS-X51 instead.
