Synology DX517 inc. 5*WD RED 4TB NAS HDDs 5 bay expansion unit

About this deal

The Synology DX517 is a 5-bay expansion enclosure designed to add extra storage capacity to a compatible Synology DiskStation NAS. Supporting both 2.5" and 3.5" SATA drives, it connects to the host NAS via eSATA and is managed directly through DiskStation Manager, with the additional bays immediately ready to use once connected. On-the-fly volume expansion means storage and services on the host are not interrupted during expansion, and hot-swappable drive trays allow drives to be installed or replaced without powering the system down. This listing comes pre-populated with five WD Red 4TB NAS hard drives, making it a ready-to-use bundle. WD Red drives are designed for NAS systems, whether for home or small office use, and can run 24/7 without issues, with the 4TB model suited to 1 to 5 bay configurations. They include Rotation Vibration (RV) sensors to anticipate and counteract disturbances caused by increased vibration common in multi-bay NAS systems. Sold in used condition.
