Uwe Schindler commented on LUCENE-9576:
---------------------------------------
bq. Think of a combined raid with ssd + rotational disk...
For a long time there were or still there are hybrid harddisks with some
integrated SSD used as cache for often read or written blocks.
I agree with the plan here: remove the complex logic and just assume from
Lucene 9 on that the default is SSD, unless user sets another default.
Solr should be separate issue to remove it from metrics. IMHO, Solr should
bring some easy setting or at least an example in default solrconfig.xml how to
enable/disable that. I posted my known solution in the mailing list answer
stated above.
In short: +1 to remove and default to SSD behavior of CMS.
