Sorry for the late reply here, just noticed this. You're correct that figure was wrong, that metric was supposed to be per day, not per minute. Its actually closer to 47mm per day now, so roughly 33k docs/min.

Mongo's own published benchmarks note that a balanced YCSB workload of 50/50 read/write can hit 160k ops/sec on dual 12-core Xeon-Westmere w/ 96GB RAM [1].

Notably that figure was optimized for throughput and the journal is not flushed to disk regularly (all data would be lost from last wiredtiger checkpoint in the event of a failure). Even in the durability optimized scenario though, mongo still hit 31k ops/sec.

Moving beyond just MongoDB though, Cockroach has seen 118k inserts/sec OLTP workload [2].
