A perfect NAS!
I was looking for a NAS to store personal files, movies but also to make an NFS disk for virtualization.
This one is perfect. I have 4 disks of 2TO in raid 5, which allows me to have a read/write speed of 200Mb/Sec.
On the functionality side, I have a VPN access, an NFS server, a file server and a media center. I get the status of the synology server with SNMP.
The NAS is easily manageable and really powerful!
