EmonCms on D-Link DNS-320L with FunPlug, is it possible?

Started EmonCms last year with a RPI, but ended because of SD card failure due to writing limitation.

Actually started to test the RPI + external HDD, but temporally on wait due to a faulty HD power supply.

Question: is it possible to use a DNS-320L (rooted with FunPlug) as an external HDD since it has an USB port.

Anybody has experimented this configuration, or, any suggestion or link to start this?

Thanks, Dino
