Updated 11/10/15: Changed name from "2014" to "Second Generation" per iXsystems request. Charts screenshots were not updated. Updated features table.

If you like to "do it yourself", you've probably considered building your own NAS using the FreeNAS open source software based on the FreeBSD operating system. If you'd prefer an off the shelf pre-built NAS, but still want to use FreeNAS, the FreeNAS Mini is iXsystems' product for the SOHO market. They also offer enterprise-level systems based on FreeNAS under the TrueNAS product line.

Several years ago, Doug Reid covered iXsystem's FreeNAS Mini and included background on how FreeNAS came to be. This review covers the Second Generation version (Gen 2) of the FreeNAS Mini, which features new case, processor and motherboard and an updated operating system. In addition to our normal suite of tests, we also tested the FreeNAS Mini with an optional 10GbE connection.

For comparison throughout the review I'll be using the QNAP TVS-471-i3-4G High-performance Turbo NAS and QNAP TVS-463 Golden Cloud Turbo. Both of these were also reviewed using our latest NAS benchmark tests and were also tested with 10 GbE connections.

The FreeNAS Mini Gen 2 is built in an off-the-shelf Ablecom CS-M50 case. The callouts below show the front panel of the FreeNAS Mini. The tool-less drive trays are hot swappable, and the drive bay cover, shown in the product shot at the top of the review, is lockable.

The photo below shows the rear panel of our review unit. As you can see, the power supply is built in and takes a standard AC power cord. For those of you who still remember serial ports, the FreeNAS Mini has a serial port (default 9600) as well as an IPMI (Intelligent Platform Management Interface) port for out-of-band management. Note that the optional 10GbE dual port card has been installed on the right.

Both the IPMI and the Gigabit Ethernet Ports have two LED indicators. One shows Activity/Link, and the other shows Speed. Note that there are slightly different indications for the IPMI port and the Gigabit LAN ports.

The FreeNAS mini is based on the ASRock Intel Avoton C2750 ITX Motherboard and CPU combo. DIYers can find the complete board (without memory) on Amazon for $390. The board features one PCI-Express 3.0 slot, eight SATA3 ports and four SATA2 ports. Only 3 USB 2.0 ports are supported. As shown in the rear callouts above, there are also 2 RJ45 Gigabit LAN and one dedicated IPMI dedicated LAN PORT. The image below shows the main board with a large heat sink installed.

The QNAP TVS-471 proved to be difficult to disassemble, so we weren't able to extract individual component part numbers as we normally do. However, I've taken what information that we were able to determine for key components and put it into the component summary comparison table below. Note the FreeNAS uses ECC RAM.
