The Lenovo ThinkSystem DE4200H is a dense 4U storage enclosure designed for high-capacity data centers. It holds up to 60 hot-swap drives, balancing space efficiency with robust cooling. I've seen it used for massive archival or backup pools where rack space is tight but storage needs are huge. It's not flashy, just practical and reliable for bulk data.
