With the Synology DS925+ + Seagate Ironwolf 12TB Duo Pack, you can create a server for your work files or favorite games and store all your data on the 2 included Seagate IronWolf 12TB internal HDDs. You place these hard drives in the NAS, and you can get started right away with making backups or gaming. The DS925+ has 2 Ethernet ports with a speed of 2,500 megabytes per second. This way, you can quickly transfer 4K videos, games, or other large files to your laptop or desktop, for example. The NAS has room for 4 hard drives in total, with a total storage space of 200TB. This lets you store large 4K and 8K video files and make backups for 300 business laptops. These slots support 2.5-inch or 3.5-inch HDDs and SSDs. You can also install 2 M.2 SSDs. This lets you create fast cache memory, so you can open frequently used files within a few seconds. Thanks to the 4GB internal RAM, you can work in multiple light programs at the same time. The NAS is also suitable for RAID setups, so you can create 1 large storage space.
Great NAS. Despite the vendor lock for hard drives, I bought this NAS anyway. There's a script on GitHub to use drives from other brands. It works great, and I highly recommend it.

The product works well. I did have to install it several times before the optimal configuration was complete. This was because different types and sizes of hard drives were used. That's also a plus (you can combine multiple types of hard drives).
