Using >16TB drives in a Synology DS1821+

[ed]

You're absolutely right to consider upgrading your Synology DS1821+ NAS for increased capacity, and it's great to hear that you plan to replace the 14TB drives with larger ones. While the compatibility list may not have caught up with the latest drives, there's usually a workaround. You can indeed use drives larger than the officially listed ones, but you might receive a warning message in Synology's Storage Manager. This warning is essentially a precaution and doesn't necessarily mean the drives won't work.

Here's a helpful guide on how to disable the compatibility warning if you encounter it: Disable Compatibility Warning Guide
