Use Case
3.2 TB balances mixed-use endurance with a node cost that allows eight or twelve drives per server. It is the capacity used where the working set fits but the write rate is high — OLTP replicas, message queues and container registries — and where a read-intensive drive of the same size would exhaust its rated writes early.
