QNAP X70/X70 Pro series have been very well received by the users ever since they were launched. However the differece between 2 units is not appearant , not from the name at least that suggests pro to be higher professional version.
|QNAP TS-470||QNAP TS-470 Pro|
|TS-470 is targeted towards Businesses||TS-470 Pro is targeted towards Power home users|
|Lower processor Dual Core 2.6. Sufficient for Most of the enterprise features||Higher processor i3 3.3. This is for Transcoding videos real time|
|DLNA not available , not being an enterprise feature||DLNA available with real time video transcoding|
|4 Network ports for Trunking or Load balancing||2 Network ports only|
In a Nutshell, if you are a business user , not requiring the DLNA , go for TS-470. If you are home user, looking at a powerhouse to drive your home theatre setup, go for TS-470 Pro.
