Description

You can place up to 2 hard drives in the Synology DS725+ standing NAS and store up to 52TB of documents, media, and other files. You can use 1 hard drive to store your files and 1 to automatically create backups, for example. Thanks to 4GB RAM, you can smoothly stream movies in Full HD or Quad HD via Plex. You can also work in the same server with 5 people at the same time. The NAS performs 2 tasks at the same time thanks to the Dual-Core AMD processor. That way, you don't experience any lags or slowing down while you work. You can also create a fast cache memory thanks to the 2 M.2 SSD slots. As a result, the NAS can read your data faster than with only HDDs. You also have 2 Ethernet ports that both support 2.5GbE. That way, you always have a fast wired connection for your NAS.

After my third Synology NAS still no

I already have experience with Synology NAS (DS920+ and DS1522+).

Installation is easy, the quality is excellent, and the software offers more than just data storage.

I use the DS725+ as a ROON server for music at home and on the road. It works perfectly, and with two 4TB hard drives in RAID 1, it holds enough music for hours of listening pleasure.

In my case, it's a great device, and I think anyone looking for a NAS will be happy with it.

Already have experience with the Synology DS124 as a data backup. I purchased this NAS for using Docker Containers. I upgraded the memory to 8GB [D4ES04-4G 4GB DDR4 SODIMM CL19 2666MHz]. The 28 containers run very smoothly on this NAS. [Synology Plus Series HDD 4TB]
