Looking into the hard drive bay area, we can see the four SATA power and data docks which each of the drives connect to as the trays are locked into position.
Inside the Chassis, there is not a whole lot to it. Above the drive bay area and behind the LCD is a large mostly empty area that allow for cables to pass through from the motherboard to the daughter boards. We can also just see the 90mm fan at the rear which draws air in and through the drive bay area.
Nestled to the right of the NAS box is the motherboard. The TS-419P II is power by a Marvell 2.0GHz CPU core with 512MB of DDR3 RAM. The operating system is loaded onto a 16MB flash IC and can handle upto 12TB of RAW capacity and a SATA II interface.
Each of the drive trays are individually labelled for a simple reminder as to which drive is which. When the trays are inserted into the drive bay, the latch on the front simply clips and locks into place. Removing is as simple as lifting the latch up, which is a firm fit, and then pulling the drive out of the bay.
