SKU CH-4WBV-9B0RT

12-bay SATA rackmount enclosure adds raw drive capacity to compatible Synology NAS systems

  • Rackmount form factor fits standard server cabinets
  • SATA interface supports broad drive compatibility
  • Diskless design lets you choose your own drives

Synology RX1225RP 12-bay SATA expansion

The Synology RX1225RP is a 12-bay rackmount enclosure that connects to a compatible Synology NAS over SATA. It adds raw drive slots without an embedded operating system. IT administrators and small-business operators use it to grow capacity behind a single management interface.

Capacity and headroom with twelve SATA bays

Twelve 3.5-inch bays accept SATA hard drives or SSDs so total raw space scales with the drives you install. The unit stops at twelve devices; workloads that need more simultaneous spindles or a second controller must look beyond this chassis.

Highlights

  • 12-bay expansion adds high-density capacity
  • Rackmount form factor fits standard server cabinets
  • SATA interface supports broad drive compatibility

Questions about this item

Will the 12-bay SATA enclosure connect to my existing Synology NAS without replacing its current drives?

The RX1225RP attaches via the host NAS expansion port, so your original drives stay in place while the 12 additional SATA bays add raw capacity.

How can I confirm the 12 SATA bays are recognised after I cable the RX1225RP to my NAS?

In DSM open Storage Manager; all 12 new drive slots should appear under the expansion unit with healthy status and correct model names.
