Key Features

  • Intel N95 Quad-Core CPU: Clocked up to 3.6 GHz, providing ample performance for file transfers, media serving, and light virtualization.
  • Triple M.2 SSD Slots: Three M.2 slots allow you to configure SSD caching or create separate high-speed storage pools, ideal for databases and virtual machines.
  • Dual 5GbE LAN Ports: Two 5GbE interfaces support link aggregation and SMB multichannel, achieving combined speeds of up to 1020 MB/s. Perfect for video editing teams and large file sharing.
  • Up to 84 TB Total Capacity: Combine two HDD bays (up to 44 TB each) with three M.2 SSDs (up to 4 TB each) for massive storage expansion.
  • TOS 6 Operating System: Intuitive management interface with apps for Docker, virtual machines, Plex/Emby/Jellyfin, CloudSync, TerraSync, and more.

Compatibility Guide

  • HDD/SSD Compatibility: Supports 3.5-inch SATA HDDs and 2.5-inch SATA SSDs. Check the official compatibility list before purchasing drives.
  • M.2 SSD Compatibility: Accepts M.2 2280 NVMe SSDs, preferably PCIe 3.0 x2 or x4.
  • Network Environment: To fully utilize 5GbE, you need a compatible switch or network adapter. It works with 1GbE networks but speed will be limited to 1 Gbps.
  • Memory Upgrade: Comes with 8 GB DDR4 SODIMM (non-ECC). Expandable up to 32 GB.

Ideal Use Cases

  • Creative Team File Sharing: Share large video projects and design files at high speed within a small team.
  • Small Office Backup Server: Use the Business Backup Suite to centralize backups for PCs and servers.
  • Home Media Server: Stream 4K/8K content with Plex, Emby, or Jellyfin, leveraging hardware transcoding.
  • Docker and Virtual Machines: Run development or testing environments directly on the NAS.

Upgrade Considerations

  • Diskless Model: You must purchase HDDs/SSDs separately. Factor this into your budget.
  • Network Bottleneck: To enjoy 5GbE speeds, your clients must also support 5GbE or higher. Older hardware will limit throughput.
  • M.2 SSD Usage: When used as cache, effectiveness depends on your access patterns. Random I/O workloads benefit the most.
