NAS products are equal parts hardware performance and software features. One compliments the other in a balanced product. You need more hardware performance to run more software features at the same time.
The N4560 uses the Thecus "Intelligent NAS" finder application.
To setup the N4560, Thecus allows two options. Here we have self-creation where the NAS selects the RAID mode based on drives installed, or second the manual RAID creation mode.
The N4560 uses the relatively new Thecus OS6, as such many of the features found on the N2560 are also found here. Though, with the N4560, you do get access to a few value added apps. Included in these are access to SNMP, NAS Stacking, iSCSI, Active Directory and LDAP servers.
