Per the article, it’s all “Plus” models from 2025 on, which definitely includes desktop 2-8 bay units.
I have been a happy enough Synology user since 2014, even though I had to hardware repair my main DS1815+ twice in that time (Intel CPU bug and ATX power-on transistor replacement).
Other than two hardware failures in 10 years (not good), the experience was great, including two easy storage expansions and the replacement of one failed drive. These were all BYOD, and the current drives are shucked WD reds with a white sticker (still CMR).
I happily recommended them prior to this change and now will have to recommend against.
