Hi there you are viewing a used QNAP TS-419 II desktop NAS with 2.0 GHz Marvell CPU and 4 HDD slots with 4 x 2tb seagate barracuda drives preinstalled. Supports up to 16TB of disk internally ( 4 x 4TB ) I have included a screenshot with the original disks installed to show it working so is a simply plug it in, connect it to your network and you're good to go.
