Dear Yvon..
This product recommend me guy from PC store (I was explain him what I want to do, and he recommend me your product N299).
Few things:
1.) N4100+ or N5200 is near to 4x more expensive then N299.
2.) We as small company don't need so huge NAS server as N4100+ & N5200 are. Our database have about 1-5 GB, so we will not utilize storage with 5 HDD's with capacity > 3TB.....
3.) There is no difference between data which creating entertainment and database.

4.) I don't want to use full capacity of the HDD, but I wan't to be able to remove (manage) those partitions and create only one partition (exept partitions for OS & SWAP). Linux OS allow root /users to do this..
Regards...
Paul
