Introduction

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 summarizes key components and compares with the TS-651 / TS-851.

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.
