Our Take

Best for: Small business users needing a compact, high-performance NAS with 4K transcoding.

5-inch drive bays into a compact, desktop-friendly chassis. It's built for small offices that need reliable file storage and sharing without taking up much space. With dual Gigabit LAN ports, it delivers over 220 MB/s reads and 190 MB/s writes even with encrypted transfers, making it snappy for daily use. It also handles 4K video transcoding on the fly, so you can stream media to multiple devices without hiccups. The included DiskStation Manager (DSM) software is rich in features, from snapshot-based backups to cloud sync. The RAM is upgradeable from 2GB to 6GB, which helps with virtual machines or heavier workloads. 5-inch drives. The RAM is also DDR3L, not the newer DDR4, but for most NAS tasks the difference is negligible. 99 (7% off retail), it's a great value for a six-bay unit with this level of performance and software support.
