Terra Master is a name new (to me at least) to NAS manufacturing. There is a comprehensive review of the new Terra Master NAS over at http://us.hardware.info.
The F2-NAS 2 is a two drive bring your own disks enclosure with a striking design. The case has a handle on the top for easy transportation. The TerraMaster F2-NAS 2 runs on a Marvell 6282 1.6 GHz ARM processor and has 512 MB RAM and 512 MB flash memory making it fit in the more affordable NAS market.
Performance of this new NAS also fits within the budget segment of NAS boxes:
The Terra Master F2-NAS 2 certainly isn't the fastest NAS we've tested in recent times. It's low in the chart, with a write speed of 46.1 MB/s and a read speed of 58.4 MB/s.
