+1 I wasn't aware that this module is obsolete and was trying to start it a few weeks ago. We develop a home-made solution some time ago to monitor smart data from both HDD (uncorrected errors, grown defect list) and SSD (WLC/TBW). But keeping it up to date with non-unified disk models is a nightmare. Alert : "OSD.12 is going to fail. Replace it soon" before seeing SLOW_OPS would be a game changer! Thanks!
