The DiskStation DS419slim 4-Bay NAS Enclosure from Synology is a cube-shaped device that provides on-the-go file access and sharing with secure file transfers. Designed to serve as a clever and reliable partner, it keeps your photos, videos, and files well organized. It is equipped with four 2.5" SATA HDD/SSD drive bays that support RAID 0, 1, 5, 6, 10, Basic, and Synology Hybrid RAID. Each RAID mode provides performance gains, data redundancy, or a combination of both. For those who do not need the benefits of a RAID, JBOD is also available.
