Installing the hard drive was easy enough. Looks ok. Creating the shares & folders was covered by the handbook. If you google for Arkara, made by Keago,you should find a more professional review, than I can provide. The setup, only lets you format to FAT32, so, you cannot put files bigger than 4GB onto it.
It can be used as a Usb drive or NAS, but not at the same time. FTP, setup might be more of a challenge for a novice, you might need to port forward your router.
Media sharing, looks easy enough, but I although I can get my Samsung TV to see the NAS, it won't play any media files, this could be, because the Arkara is uPnP, but not DNLA compliant. When opening iTunes on one of the pc's on my network, the device shows up on the LHS, but not the other pc. There is something about newer versions of iTunes having this problem. Look at the QNAP forums. I haven't managed to get the shared printing to work through the NAS, but I haven't really tried to sort it out.
Overall, I'm quite pleased with this.
Since this review, I have used the Bitorrent client. Well, I have given up using the Arkara as a NAS. Although, the Arkara said the Torrent download was completed, 100%. I then tried the file & it wasn't. So I now us it just as an external usb drive.
Having just received a comment about how I gave this four stars, I have now changed it to two.
