5 Things to Know About the Synology DS1520+

It uses the Intel Celeron J4125 processor This is the same chip found in many other NAS units, so performance is predictable and reliable.

It has five drive bays That is one more than the typical 4-bay NAS, giving you extra storage flexibility without jumping to a larger chassis.

It runs Synology’s DSM operating system DSM is widely considered the best NAS software for ease of use and feature set.

The extra bay is the main selling point If you need more than four drives but not a full 6- or 8-bay unit, this is a practical middle ground.

It is not a performance upgrade over cheaper 4-bay models The J4125 is the same processor used in many lower-cost units, so do not expect faster file transfers or transcoding.
