As someone who works at a platform company that operates several (very) large log ingestion systems, if you're not indexing the logs usefully, having stored them on SSDs isn't doing much for you. It's just a weird comparison to make, is all I'm saying.
Indexing that is 75x the original uncompressed data volume?
Because then I might accept the cost!
Realistically all of these systems use some type of data compression such as Parquet files, so the data on disk is likely smaller than the ingested data.
