The Thecus N4200 is a self-contained NAS unit. It is one of the first NAS servers I’ve seen with the new Intel Dual Core D510 Atom processors. This is the new low-voltage dual core processor Intel released late last year along with the N450 which is the single core version of this CPU. The N510 CPU is on the 45nm die process and has an Intel GMA3150 integrated into the CPU. The D510 runs at 1.66GHz and has 512KB of L2 cache and supports DDR2-800MHz memory.

A NAS Server like the N4200 has a Disk On Module or DOM containing all of the critical software to run the system. If the DOM stops working for any reason, the files on the NAS server could be inaccessible. The N4200 has Dual DOMs, meaning that if one fails the secondary DOM reprograms the primary DOM if it fails meaning your system has an added layer of protection if the primary DOM goes down. This is a great feature introduced by Thecus onto many of their NAS servers.

The N4200 has two displays as well, one LCD and one OLED. The LCD display displays critical system information including the hard disk and network status. The OLDED allows you to change a number of system settings such as WAN, LAN, Link Aggregation languages and more. One of the issues with a NAS is a sudden power outage causing data to be lost. The N4200 has a Battery Backup Module with a lithium-ion battery that saves all unwritten data to hard disks saving data and system integrity. The N4200 has combo SATA hard disk bays allowing both 3.5” and 2.5” drives to be installed.
