## Long description

The ASUSTOR Lockerstor 4RD is a 1U rackmount NAS designed for small and medium businesses that require space-efficient, expandable storage. It is powered by a Quad-Core Intel Atom C3538 CPU at 2.1 GHz and equipped with 8 GB of DDR4 RAM, offering stable performance for file sharing, backup and virtualization tasks. The unit provides four drive bays for SATA HDD/SSD, four Ethernet ports (two Gigabit and two 2.5GbE) and PCIe expansion capability for 10GbE or other add-on cards.
Advantages
The Lockerstor 4RD combines enterprise-grade processing and DDR4 memory in a thin 1U chassis to deliver reliable multi-user access and consistent throughput. Dual backup power supplies and multiple Ethernet ports enable redundancy to minimize downtime, while PCIe expansion and USB 3.2 ports offer flexible options to increase network speed and storage capacity. The system uses Btrfs and Snapshot Center for point-in-time data protection and includes ADM security features to reduce the risk of ransomware.
Suitable for

How to use
Install up to four SATA drives into the drive bays and configure RAID according to your redundancy and capacity needs using the ADM web interface.
