According to our NAS expert
With the 2 included internal HDDs with 12TB of storage, you can get started with the NAS right away.
Place up to 2 HDDs and 2 M.2 SSDs in this NAS for plenty of storage space and fast cache memory.
With 4GB of RAM, you can work with 5 to 10 users on the NAS at the same time.
This NAS doesn't come with SSDs.
With the Synology DS725+ + Seagate Ironwolf 12TB Duo Pack NAS server, you can create wireless storage space and store your data on the 2 included Seagate IronWolf 12TB internal HDDs. You can install a total of 2 hard drives in this NAS. This gives you 1 drive to store your files and another drive to make automatic backups. Thanks to the 4GB RAM, you can smoothly stream movies in Full HD or Quad HD via Plex. You can also work on a server with 5 different people at the same time. In addition, the NAS can perform 2 tasks at once thanks to the Dual-Core AMD processor. This way, you won't have issues with delays or stuttering while you work. You can also create fast cache memory with the 2 M.2 SSD slots. This lets the NAS read your data faster than when you only use HDDs. In addition, you get 2 Ethernet ports that both support 2.5GbE. This way, you'll always have a fast wired connection for your NAS.

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]
