whats the best Network Attached Storage out of these 2

[mark35]

QNap Turbo Station TS-209 NAS Enclosure or D-Link DNS-323 2-Bay Network Storage Enclosure

 

[Snow-Munki]

Qnap but it is bit more expensive. But from the spec is better, ie takes USB external hard drives.

About £40 more.... I've got neither though
