Your own personal private cloud in the palm of your hands. DS416slim might be diminutive in size at less than 2.5 liters, but it packs comprehensive file management capabilities with versatile dual LAN ports and hot swappable trays for maximum service continuity.
DS416slim is specially designed to fit in four 2.5-inch drives for flexible drive management. The small server consumes only 17W during operation, leaving lesser carbon footprint than traditional 4-bay NAS counterparts. Quiet and smaller than your palm, DS416slim easily blends into your environment.
Storage management is easy with Synology Hybrid RAID (SHR) technology. SHR is an automated RAID management system allowing you to easily create and expand storage volumes and migrate RAID types without requiring details on RAID. SHR provides 1 to 2-disk redundancy to safeguard your data during drive failures.
SHR maximizes the data capacity of your RAID when different sizes of HDDs are used. Calculate your RAID needs.
For novice users who have no technical background and still want to protect their data using RAID technology, a convenient installation wizard will guide you through all the steps during your first installation.
You can add new disks on the fly in Storage Manager with a simple click.
While creating a volume, you can plan ahead and leave empty and unallocated space for future usage.
Turn your Synology NAS into a home media hub and stream your digital contents to computers, mobile devices, Samsung TV, Apple TV, Google Chromecast, and DLNA devices.
