Questions about DS1621+

Hello, no, it is definitely not. If it were, my shelf would already be broken :-).

Yes, the Synology DS1621+ can be used as a multimedia server. Here are a few key points that make it suitable for this purpose:

- Performance: The DS1621+ is equipped with an AMD Ryzen V1500B quad-core 2.2 GHz processor, which offers sufficient performance to handle multimedia streams without transcoding, especialmente if you use direct play.

- Storage capacity: It has six storage bays and can be expanded to 16 bays with two DX517 expansion units, providing ample storage capacity for your multimedia files.

- Multimedia applications: The DS1621+ supports various multimedia applications, including Video Station, Photo Station, and Audio Station, as well as integration with iTunes Server. It can also function as a Plex server, especially if you don't need frequent transcoding.

- Connectivity: It offers several connectivity options, including Gigabit LAN, USB 3.0, and eSATA ports, as well as the option of adding a 10GbE network card to improve transfer speeds.

In short, the DS1621+ is a robust, high-performance media server solution capable of handling your media storage and delivery needs.

The HDDs work no matter what size. It is best to use SHR - RAID then the disc size does not matter. With other RAIDs, the maximum size is that of the smallest disc.
Unfortunately I cannot answer the second question.

The DS1621+ itself has no built-in WLAN. However, you can connect it to a router/satellite via LAN cable and then access the DS1621+ via WLAN. The prerequisite is that the router/satellite is WLAN-capable.

Yes, it is possible.

Yes, they can. Please note the following points:
1) If you add larger hard disks later, the entire storage capacity of the new hard disks cannot be used, depending on the selected RAID configuration.
2) The expansion of the storage pool / volume with the new hard disks can take some time (depending on the RAID configuration, hard disk size, this can also be 1-2 days).
