It runs a Marvell Amarda dual core CPU clocked at 1.33GHz with 512MB of RAM. On the inside bottom of the NAS is the motherboard.

The NAS can only recognize a maximum of 16TB volumes, so you would need to create multiple volumes and allocate accordingly if you have big storage needs. The DiskStation can hold four hard drives for a total of 40TB of storage, although the software’s maximum volume size is 16TB. The package does include four of the Seagate IronWolf drives. The review unit I received had two 2TB Seagate “IronWolf” hard drives that are specifically made for the 100% duty cycle of an NAS. There is a door on the back above the ports that opens to reveal four hard drive bays. The USB ports also allow you to connect external drives, making the storage of the device virtually limitless.

The device does not come with Wi-Fi built in, but you can use a Wi-Fi adapter in one of the USB ports. At the bottom of the back is the power connector port, a LAN connector, one USB and one USB3 port.
