This will be a post for all the new and upcoming models that I will update with data sheets and specs. Considering that Synology is pushing a lot of new models, I felt it would be more clean to separate these type of info into a separate article then to keep them inside a dedicated DS1621xs+ article.
Info on DS1621+ and DS1621xs+ will remain in a dedicated article here, as well as the x20 model lineup here.

Just like the new DS1621+, looks like we are getting another AMD Ryzen V1500B based NAS but this time and 8bay upgrade to the familiar DS1819+. This might very well be the last model we will see before the end of the year
Some hardware specifications about the upcoming model:

New 8bay half size rack size model that will probably come out in January of 2021. Both unit are 298mm (RS1221+) and 399mm (RS1221RP+) in depth, so they will be a perfect fit for a small rack enclouser.
These models have also adapted the new AMD V1500B CPU, the same one present in 1821+ as well as in 1621+, so at the moment we have 4 NAS units (all from "+" segment) running with the new CPU architecture.
Units are 10G ready via PCIe SFP+ and they provide 4x1G lan ports on the back as well. In case you want cache support you can also use the PCIe expansion by installing M2D20 or E10M20-T1 adapter cards to get 10G and NVMe support as well.
General specifications are:
- AMD Ryzen V1500B
- 4-core 2.2 GHz
- Hardware Encryption Engine (AES-NI) YES
- 4GB DDR4 ECC SODIMM
- Maximum Memory Capacity 32 GB (16 GB x 2)
- Maximum Drive Bays with Expansion Unit 12 (RX418 x 1)
- Hot Swappable Drive YES
- RJ-45 1GbE LAN Port 4 (with Link Aggregation / Failover support)
- USB 3.2 Gen1 Port x2
- eSATA Port x1 (for expansion)
