When the unit powers on the display updates at various stages. Eventually it'll just display various settings including the current IP address. Unfortunately I couldn't change the IP address this way, however I could put my own computer in the same network and change the network settings to match my own network. No software is required this way.
When you point your browser to the NAS you're welcomed by a logon screen. Admin/admin was my first guess and worked right away. So even the manual wasn't required.
The first time you log on you get a nice agreement, I decided not to read it and just accept it. Selecting the checkbox drops the agreement into a black hole, never to be seen again.
The menus are full of options, most are simple settings to set one time and never to see again. Besides some basic expected settings there also are settings to automatically turn on or off at specific times. The most interesting features still are the modules though. They basically allow you to add whatever feature you wish. (if someone created a module or you have the know-how yourself)
Unfortunately I can't set it as DHCP client, which I actually expected to be the default setting in the first place.
Considering the primary role of the N4100 Pro is storage, RAID 5 makes the most sense. However due to the limited processing power I started with a RAID 0 array as this could show different performance.
Choices for stripe sizes are plenty, I picked 128K as this is quite common. Though the default is 64K. Creating a RAID 0 array takes a few minutes. Creating a RAID 5 array takes "slightly" longer, no quick initialization unfortunately. During normal use this has to be done just once.
Removing an array sounds rather evil if you ask me.
