Overview

TS-251D-4G Overview

The QNAP TS-251D is an entry-level 2-bay NAS that targets home users looking to set up a multimedia entertainment solution (4K media transcoding and streaming) and those who just need a device to secure their data via their own personal cloud. Released back in January, the QNAP NAS comes in two models: TS-251D-4G and TS-251D-2G. Though the 2G ships with 2GB of RAM and the 4G with 4GB, they both can be expanded to a maximum of 8GB using the two DIMM slots.
