To say that the DiskStation DS225+ had a troubled launch would be an understatement. Synology controversially chose to limit the use of HDDs to its own branded drives, and that didn't go down well with its userbase. The decision made long-time DiskStation users switch to rival brands, and it contributed to UGREEN's meteoric rise in this category.
There's no doubt that NAS servers like the DXP4800 Pro and the DXP2800 have better hardware than just about any of their rivals, and Synology's short-sighted strategy lost the brand a lot of the goodwill it gained over the last 15 years. Thankfully though, the brand reversed its HDD decision, and with the DSM 7.3 software update, you can use any Seagate, WD, or Toshiba HDD with the DS225+ and not run into any issues.
