It must be TTL 3.3V compatible, thats what you will need for your nas.
I can not see if this is a 5 volt or 3.3 volt version. A 5 volt one will damage your motherboard
Typical these cables are 5 volt (because thats supplied form the usb port)
You need to find out which wire is RX, TX, tx, V+ and ground and then find pin connectors spec for the cloudbox.
from the product specification given you can find this
Red cable:VCC; Black cable: GND; Green cable: TXD; White cable: RXD
I don't have a cloudbox so I can not help you with that part, but google is your friend
this is a link to a picture form nwsp2 serial connector but it might be different on the cloudbox
