The QNAP TS-209 is a Network Attached Storage Box that gives you a two-drive, hot-Swappable, SATA RAID array in a stylish, and quiet enclosure. It features a 500Mhz CPU, 128MB of DDRII System Memory, 8MB of Flash for the operating system, a single Gigabit Ethernet port, and three USB 2.0 connectors (two in the back and one in the front.) The 209 in based on a Linux OS and supports Windows and Mac clients.
Using the QNAP 209 is quite easy. Simple plug in the power and ethernet cables, and push the power button. The first time the array powers up it will check the drives and prepare the array for use. A string of LED lights on the front of the unit gives you an at-a-glance status of power, network link, drive status and activity.
The unit only has three buttons, a reset button in the back, and power and one-touch copy buttons up front. This gives the unit an uncluttered look and creates a simple user experience.
The USB ports on the 209 can be used to connect an external USB hard drive, USB printer, flash drive, digital camera, memory card reader, and just about any other USB storage device.
The 209 automatically detected the two Seagate 250GB drives we used for the test and it asked us how we wanted to setup the unit. You can choose to stripe the array in RAID 0, giving you faster performance and the full amount of storage but much less data security — if either of the drives fail, you lose everything.
You can also choose to mirror your drives in RAID 1, essentially giving you two identical sets of data – This is slower and cuts your usable space in half, but it is far more secure as you can suffer a drive failure and still not lose any of your data. If any of the drives does fail, simply power down the unit, replace the failed drive, and power it back up. The 209 will automatically resync your data.
You can also have the 209 setup a Linear Disk Volume – a JBOD, or Just a Bunch of Disks, which will give you two different drives in the same array. This isn’t as fast as striping, and it doesn’t give you the redundancy of mirroring, but you get to keep the maximum storage without risking the loss of ALL your data with a single drive failure.
