Lenovo ThinkSystem USB 3.0 Internal Host Interface Drive Dock

The Lenovo 4T27A80485 is an internal drive dock built for ThinkSystem servers, giving administrators a straightforward way to add removable storage inside a standard chassis. By sliding into a bay that follows the 5.25 inch half height format, the dock integrates cleanly with existing hardware without the need for brackets or external cabling.

Connection to the host system happens over USB 3.0, letting backup or archival jobs travel at speeds that keep pace with today’s data volumes. The single bay accepts one RDX cartridge and supports capacities as large as 4 TB, making it suitable for everything from daily incremental backups to long-term off-site rotation.

Because the dock is hot-swappable, IT staff can replace cartridges without shutting down the server, reducing maintenance windows and keeping critical applications online. This capability is especially useful in branch offices, lab environments, and small data centers where downtime must stay near zero yet reliable offline copies are still required.

For administrators who want a secure, portable, and easy-to-manage backup medium that lives inside the server until the moment it needs to be removed, the Lenovo 4T27A80485 offers a practical, enterprise-ready answer.
