The 12 internal 3.5"/2.5" SATA bays scale out to a full 48 drives by daisy-chaining three RX1225RP expansion units, giving a maximum raw capacity of 1,152TB (using 24TB drives) for large file shares, backup targets, surveillance archives, or virtualization storage. Networking is built around 2x 10GbE RJ-45 ports plus a dedicated management port, with a PCIe 4.0 expansion slot available for an add-in 10/25GbE NIC or, per this listing, a GPU for hardware-accelerated video transcoding. It runs Synology's DSM operating system with Btrfs, Snapshot Replication, and Synology High Availability support for business-continuity deployments where downtime isn't an option. Dual redundant hot-swappable power supplies round out the enterprise reliability story, letting the unit keep running through a single PSU or power-feed failure without any interruption to storage availability.
