Budget-conscious consumers often turn to lesser-known manufacturers for products that offer a lot of value at a very affordable price. Sometimes they find a real bargain and the relatively low price offsets whatever drawbacks the product may have.
That's just what they may find with the TRENDnet TN-200 2-Bay NAS Media Server. The TN-200 comes in two models, the diskless model that is our review sample (~$100) and the TN-200T1 with a single 1 TB drive (about $190). As with all two bay NASes, the TN-200 supports RAID 0, RAID 1, (mirroring), individual volumes per disk and JBOD (Just a Bunch of Disks).
As you can see from the image above, the TN-200 has a white plastic case. The majority of the front panel has a molded-in grill that provides front to back airflow for cooling. Unlike many NASes that mount the drives horizontally through the front panel, the TN-200 has a slide-off top that allows you to mount the drives vertically.
You just line up the power/data connectors on your eSATA disk with the corresponding connectors on the TN-200's PCB and gently slide the disk into place. You'll feel it seat in the connector, and you'll know that it's in the right location when the screw holes in the mounting bracket line up with the mounting holes on the disk. You secure each disk with two screws - one in the front and one in the rear bracket. In the image below, I didn't screw in the drive to the right hand bracket so you can see how the screw holes line up.

The front panel of the TN-200 is fairly simple. There's a power button an indicator for each disk, and a USB sync button. The chart below summarizes each indicator.

The image below shows the rear panel of the TN-200. Directly above the Ethernet port, there's a Kensington lock slot. Above the fan grill, you'll find a slide lock that locks the top cover in place. The Ethernet port has two built-in indicators for link and activity.

The TN-200 is powered by a Marvell "Kirkwood" 88F62702 running at 1 GHz. Other key components are found in Table 1, with summaries for three other sub-$150 NASes. Note the TN-200 uses the same amount of memory as two of the other devices and has the same processor as the D-Link DNS320L. The TN-200 drew 14 Watts with two WD RED WD30EFRX 3 TB (SNB provided) drives spun up and 7 W when the drive spun down after the programmed idle drive time.

Table 1: Component summary
The TN-200 relies on a fan for cooling. By default, the fan is set for "Auto Speed", which lets it spin up to a higher speed after a period of heavy I/O activity. When the fan is spinning faster, I'd rate the NAS as moderately loud, and the fan only adds to the noise made by the drives. Even with the disks spun down and the device in "hibernate" mode, the fan is still running, so you'll hear the constant hum in a quite office. I guess that I've gotten spoiled by the quietness of the other NASes that live on a shelf near my desk.
For those of you who like the circuit board image, the photo below shows the component side of the PCB. The Marvell SoC is located right in the center of the board.
