I am planning to buy a ZyXEL NSA 320 box. Can I connect an external hard drive to the USB port of the NSA 320 and make it available over the network – without having internal drives?

Why would you not want to use the internal drives? – ioSamurai Jul 19 '12 at 21:15
i do not want to buy them now. Wait for black friday. I do have 3TB external USB Hard drive – Amareswar Jul 19 '12 at 21:17
ah this makes sense now that I've read more about the product and found that it doesn't ship with drives :) – ioSamurai Jul 19 '12 at 21:18

The product details here seem to indicate that it will support external drives:

  • File system support

Internal HDD: EXT4

External HDD: NTFS, EXT2, EXT3, FAT32, ReiserFS, XFS

Here is a review with some more clues...

  1. Other NAS backup strategies backup drives to externals as files when schduling "jobs". They are accessible from your computer using the external drives if the NAS fails. This box does scheduled jobs in a proprietary format, so you would have to by another Zyxel to restore. There ARE two ways around some of this: A: A setting for the front button will let you backup one of your shares and mirror it to an external drive. You cannot schedule this though. B: You can use drag-and-drop or software on your computer to cause files to move/mirror to an external drive as files. BUT, since you are passing through your CPU, it is slower and bound by that computer remaining on.

Honestly, it's not looking like you'll want to waste time with this...
