Your Office Has Outgrown USB Hard Drives. Here Is the NAS That Replaces Them Without Requiring an IT Hire.

A USB drive plugged into the receptionist’s computer is not a backup. It is a single point of failure with a 3-year consumer warranty that stores the entire company’s file server. The Synology DS923+ is a 4-bay NAS that turns four hard drives into a RAID-protected, snapshotted, cloud-synced file server that any small business can set up in an afternoon. With an AMD Ryzen R1600 dual-core processor, 4 GB ECC RAM (expandable to 32 GB), dual 1GbE ports with link aggregation, an optional 10GbE upgrade slot, and Synology DSM 7.2, the DS923+ is the NAS that replaces the stack of USB drives without requiring a storage engineer.
