Product Features
Technical Overview
The TS3430DN utilizes a single Annapurna Labs Alpine AL524 processor operating at 2GHz with four processing cores. This ARM-based architecture provides power-efficient operation suitable for continuous 24/7 NAS workloads. The 2GB of DDR4 SDRAM supports the operating system and caching mechanisms for improved file access performance.
Storage management is handled through comprehensive RAID support including RAID 0, 1, 5, 6, 10, and JBOD configurations. The system accommodates up to four 3.5" or 2.5" SATA hard drives or SSDs, with two bays populated in this configuration. Network connectivity features two RJ-45 ports supporting both standard Gigabit Ethernet and faster 2.5 Gigabit Ethernet standards for flexible deployment in mixed-speed network environments.
Protocol Support
The TeraStation 3430DN supports multiple file access protocols including CIFS/SMB for Windows environments, AFP for macOS compatibility, FTP/FTPS for file transfers, SFTP for secure transfers, NFS for Unix/Linux systems, and iSCSI for block-level storage provisioning.
- Windows (CIFS/SMB)
- macOS (AFP)
- Linux/Unix (NFS)
- iSCSI Block Storage
Key Product Advantages
This TeraStation model combines pre-configured storage with enterprise-grade data protection features in a compact desktop form factor. The included 4TB of storage across two drives provides immediate capacity while leaving two additional bays available for future expansion or RAID migration.
These strengths make the product easier to deploy and manage in real environments, especially where reliability, usability, and day-to-day operational continuity matter. Notable benefits include Pre-Populated Drives, Expandable to 4 Drives, Hardware RAID, Dual Network Ports.
Deployment / Use Cases
The TeraStation 3430DN is optimized for small to medium business environments requiring centralized file storage with data protection. Its desktop form factor makes it suitable for office environments where rack space is limited or unavailable.
Typical deployment scenarios include departmental file servers, backup targets for workstations and servers, and shared storage for collaborative projects. The dual network ports enable link aggregation for increased throughput or failover configurations to maintain availability during network disruptions.
SMB File Server
Serve files to Windows, macOS, and Linux clients simultaneously through native protocol support. The RAID-protected storage ensures business continuity during hardware failures.
- Multi-Platform Access
- RAID-Protected Storage
- Concurrent User Support
Backup Repository
Function as a centralized backup target for workstation and server backup software. The 2.5GbE network support accelerates backup and restore operations compared to standard Gigabit Ethernet.
- High-Speed Transfers
- Centralized Storage
- Dedicated Backup Target
Physical Profile
The desktop enclosure measures 8.50" (215.90 mm) in height, 6.70" (170.18 mm) in width, and 9.10" (231.14 mm) in depth, with a weight of approximately 10.60 lb (4808.08 g) including installed drives.

User Manual
FAQ
What storage capacity comes pre-installed in this TeraStation 3430DN?
This configuration includes 4TB of total storage capacity pre-installed across two 2TB hard drives. The system has four drive bays total, leaving two bays empty for future expansion. You can add additional drives to increase capacity or reconfigure the RAID array as needed.
What RAID configurations does this NAS support?
The TeraStation 3430DN supports RAID levels 0, 1, 5, 6, 10, and JBOD. RAID 5 and 6 provide single and dual parity protection respectively, allowing continued operation during drive failures. RAID 10 combines mirroring and striping for both performance and redundancy. JBOD treats each drive independently without RAID protection.
What processor does this NAS use and how many cores does it have?
This model uses an Annapurna Labs Alpine AL524 processor with four processing cores (quad-core) operating at 2GHz. This ARM-based processor architecture provides efficient performance for NAS workloads while maintaining lower power consumption compared to some x86 alternatives.
How much memory is included and what type is it?
The TeraStation 3430DN comes with 2GB of DDR4 SDRAM installed. This memory supports the NAS operating system, file system caching, and concurrent user connections. DDR4 technology provides improved bandwidth and power efficiency compared to previous DDR3 memory generations.
What network connectivity options does this NAS provide?
This NAS includes two RJ-45 network ports that support both standard Gigabit Ethernet (1000BASE-T) and faster 2.5 Gigabit Ethernet (2.5GBASE-T) connections. The dual ports allow for link aggregation to increase throughput or failover configurations to maintain network availability if one port or switch connection fails.
What is included in the package with this TeraStation?
The package includes the TeraStation TS3430DN SAN/NAS storage system with pre-installed hard drives, a Category 5e Ethernet cable for network connection, an AC power cable, a quick setup guide, warranty documentation, and a front panel key for securing the drive bays. All necessary components for basic deployment are included.
