All-around storage solutionoptimizedto safeguard your data

MultimediaCompact yet powerful storage solution

Equipped with a dual-core processor and AES-NIhardware encryption engine, DS218+ delivers exceptional file transfer speeds. Supporting real-time 4K video streaming, DS218+ is ideal not only for protecting critical data butfor storing ultra-high definition media contents as well.

Next-generation file system for better data protection

The Btrfs file system introduces advanced storage technologies and optimized snapshots to prevent data corruption and reduce maintenance overhead. While ensuring high-level data integrity, it also offers flexible, efficient data protection and recovery tools.

  • Flexible Shared Folder / User Quota System provides comprehensive quota control on user accounts and shared folders
  • Snapshot Replication provides schedulable and storage capacity-saving data protection with 1,024 shared folder backups and 65,000 system-wide snapshots
  • File- or folder-level data restoration accelerates data recovery, providing more flexibility for businesses
  • Automatic file self-healing detects and recovers corrupted files without user intervention

4K Multimedia Server

Access and stream your 4K media content anytime and anywhere. DS218+ supports 4K H.264/H.265 online transcoding via Video Station and DS video, allowing 4K videos to be converted and played on the fly on other computers, smartphones, and media players that originally do not support Ultra HD formats.
