Synology RackStation 12 Bay Expansion Unit for: SA series:SA6400; 23 series:RS2423RP+; RS2423+ .
This Synology 12-bay expansion unit adds 12 additional 3.5" or 2.5" SATA HDD/SSD bays to a compatible Synology NAS once its own internal bays are full, rather than requiring a second, separate NAS system — the standard way to scale Synology storage without migrating to entirely new hardware. It's designed specifically for the SA6400 enterprise NAS platform and the RS2423RP+/RS2423+ rack-mount NAS series, connecting to the host system over a single MiniSAS-HD expansion cable rather than a network connection, which keeps the added storage running at direct-attached speeds rather than being bottlenecked by Ethernet.
This is a storage-scaling accessory for businesses that have already outgrown their NAS's internal drive bays but don't want to buy and migrate to an entirely new system — a common need for growing file servers, backup targets, or surveillance storage deployments. Multiple expansion units can typically be chained from a single compatible host NAS for larger-scale capacity growth, and the unit itself ships with dual power supplies for redundancy, so a single PSU failure doesn't take the expansion storage offline. Because it connects via a dedicated MiniSAS-HD link rather than a network cable, adding it doesn't consume one of the host NAS's Ethernet ports or compete with client and network traffic for bandwidth, keeping storage I/O isolated from the rest of the network.
