150% Faster with 2.5-Gigabit Ethernet

The Lockerstor 4 provides two 2.5-Gigabit Ethernet ports. Enable up to 150% faster performance than Gigabit Ethernet with compatible hardware and up to 5 Gbps using Link Aggregation.*

Four Bays with Two M.2 SSD Slots for Flexible Cached Storage

The Lockerstor 4 is a cost-effective high capacity NAS designed for enterprise environments. The Lockerstor 4 is flexible, supporting online capacity expansion and replacement. Online capacity expansion enables you to replace hard drives inside the NAS without downtime. If your budget and/or storage requirements are small, the Lockerstor 4 enables your NAS to grow alongside your needs by first purchasing smaller drives and then add more drives as you need. Additional drives can be purchased as your storage requirements grow and all drives can be fully replaced while continuing to use your NAS. Combining this with ASUSTOR’s MyArchive cold storage technology enables you to store a virtually unlimited amount of information.

24/7 Reliability and Durability

All ASUSTOR NAS are designed for and are suitable for 24/7 use. ASUSTOR NAS devices have also undergone rigorous tests, such as drop tests and burn tests to test durability in extreme conditions. Heatsinks were added to sensitive components to dissipate heat, helping to maintain the longevity of the device.

Protected From the Inside and Out

Protect your data from loss, damage and attacks with the ASUSTOR NAS. An ASUSTOR NAS is better protected by running the Linux-based ADM, employing a built-in firewall, ClamAV Antivirus, MyArchive and ADM’s various backup tools help protect ransomware even better.


Network Attack Protection

  • Firewall
  • ADM Defender
  • Cloud Backup Center offsite backups

Secure Data Transmission

  • VPN connection
  • SSL certificate connection
  • Automatic logout

Internal Data

  • MyArchive on and offsite backups
  • AES-256 folder encryption
  • Antivirus software

Access Control

  • File/folder/app isolation
  • 2-Step Verification
  • Wake-on-LAN (WOL)
  • Wake-on-WAN (WAN)

Wake Up From Anywhere

The Lockerstor 2 and 4 feature Wake on WAN technology. No specialized equipment or settings are needed to wake the NAS. Simply use ASUSTOR’s wide variety of mobile apps, including but not limited to AiMaster, AiMusic, AiVideos and AiData to turn the NAS on or off remotely. Wake on WAN helps protect data by keeping the NAS powered off when not in use; thereby helping to prevent attacks, protects data integrity by remaining powered off during power failures and Wake on WAN also saves electricity, making for an even more efficient NAS.

Protected From Ransomware

The Lockerstor comes with the most up-to-date version of ADM to help protect against ransomware attacks. Snapshot Center and Btrfs provide the ability to efficiently create snapshots to protect and easily restore lost data. Other security features found on the Lockerstor are the ability to create one or more replacement administrator accounts, a firewall by ADM Defender that features blacklists and whitelists, the ability to change default ports, disable SSH and Terminal to prevent remote attacks. MyArchive cold storage hard drive security can also be increased by implementing AES 256bit encryption.
