A lot of these background process / disk access concerns are hold overs from like 2005 when people had small 7200 rpm drives and small amounts of slow RAM. Indexing on an SSD is absolutely irrelevant to performance these days. Not sure why people still follow these archaic “make your computer optimized for audio!” when 99% of this poop is obsolete.
The reason I have mine shut off is because Windows OS level indexing is awful. Using ‘Everything’ will prove exactly how fast a drive can be indexed and searched when the feature is actually programmed well.
