Technically brilliant

I have gained this NAS from Synology after many hours of Internet research.
Order through Amazon as usual without any problems, delivery very fast despite Marketplace sellers and Amazon not directly.

HDD installation, installation and configuration were unfamiliar problem of equip. This is where Synology a Refernez, will have to nibble at other manufacturers.
Therefore, the same front off the reason for the star deduction:
- The cover is made of thin sheet metal and the housing screws just go with something pressing in, makes a less solid impression (after screwing the whole but very solid)
- To drive change until the housing must be screwed, are unscrewed hard drives and then herausgefummelt - very inconvenient for a NAS with RAID, here should have direct access from the outside possible.

The rest is so good that the above points rather only justify the withdrawal of half a star, but unfortunately this is not possible.

I have installed 4 2TB drives from Samsung and put into operation by all instructions. The disk check I skipped, thus the basic installation was finished after about one hour.
Then only create users, share folders, finished.

The configuration of the other services (iTunes server, media server, remote access via Internet, ...) is on the surface of DSM 3.0 a breeze.

Data backup via Time Machine works great with me secure iMac and the MacBook parallel. This was one of the main reasons for the acquisition of this NAS because Time Machine with external panels is annoying and you also have to remember.

The function as a media server, I have not tested it, this comes in the next few days.

All in all, highly recommended!
