I worked out that it's cheaper to write logs to high-end Samsung SSDs and then throw them away every month than to retain them in the log analytics systems of some cloud services for the same period of time.
Wait, no, sorry... that doesn't quite "paint the right picture".
The "single use" SSDs are 75 times cheaper than storing the data in the cloud.
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.
