## Long description

The Asustor Lockerstor 4RD is a 1U rackmount NAS designed for small and medium businesses that need compact, reliable, and expandable network storage. Powered by an Intel Atom C3538 quad‑core CPU at 2.1 GHz and equipped with 8 GB DDR4 RAM, this grey 4‑bay unit supports both HDD and SSD drives and fits standard server racks while offering multiple Ethernet ports and PCIe expansion for future upgrades.
Advantages
The Lockerstor 4RD delivers enterprise‑grade performance and redundancy in a thin 1U chassis. Its combination of a quad‑core Intel Atom CPU and DDR4 memory provides smooth file sharing and multitasking. Four Ethernet ports (two Gigabit and two 2.5GbE) and dual hot‑swap power supplies improve fault tolerance and network throughput. PCIe expansion allows installation of 10GbE add‑in cards, and multiple USB 3.2 ports give additional external storage options. The unit is built for 24/7 operation with heat dissipation for component longevity and firmware features to mitigate ransomware risks.
Suitable for
Small and medium business file sharing and collaboration
Backup server and centralized data storage
Virtualization light‑duty storage and media streaming
Environments requiring rack‑mounted, space‑saving NAS

How to use
Install up to four 3.5" or 2.5" HDD/SSD drives into the drive bays and mount the unit in a standard 1U server rack. Connect network cables to the appropriate Ethernet ports and power on the NAS. Use Asustor’s ADM operating system to configure storage pools, RAID level, users and shared folders. For increased network throughput, configure link aggregation across the 2.5GbE ports or add a 10GbE PCIe card. Set up Snapshot Center and regular backup tasks in ADM to protect data and enable firmware/security options such as ADM Defender and AES encryption for MyArchive drives.
Usage recommendations
For best reliability, use enterprise‑class HDDs or SSDs, enable RAID and snapshot-based backups, and install the device in a climate‑controlled rack with adequate airflow. Combine the 2.5GbE ports or add a 10GbE PCIe card to achieve higher network throughput; keep firmware and ADM security settings up to date to reduce risk from ransomware.
