How can I downgrade DSM 7 - Synology Community
community.synology.com › enu › forumFeb 15, 2021 · I'm not new to synology or NAS or networking. I've been using a 4 bay I've been using the past 3 years. I bought a DS1621+ second hand locally. It has DSM 7 on it and while the hardware is far superior to my DS918+ it runs WAY slower. By an order of magnitude slower. I'm comfortable SSH'ing in and good in linux.
