Overview

Government agencies and SMB organizations that require effective removable drive enclosures to store, transport, and protect their sensitive data rely on the CRU Rhino® Jr RJ21S.

These two carriers receive any capacity 2.5" (9.5mm) SATA hard drives and solid-state drives (SSD). The frame mounts in the standard 3.5" bay drives found in desktops and workstations.

The RJ21S enables fast drive swapping for additional storage with our TrayFree™ technology.

Metal hard drive carriers provide reliable data protection for the RJ21S. These enclosures are engineered and warranted for over 50,000 insertions using durable connectors.

The RJ21S operates at speeds up to 6 Gbps using 6 Gbps hard drives and host controllers.

Secure your data with the key lock to prevent unauthorized access to your drive or accidental removal during operation.
