  • Power and Cooling: Engineered for reliable operation in rack environments; exact power specifications depend on deployed drives and NAS configuration

The RX1222SAS is built to integrate smoothly with Synology’s ecosystem, enabling streamlined storage management across multiple devices. When used as an expansion unit, it expands capacity for existing volumes and pools, allowing you to grow storage without migrating data to a new system. The 12-bay layout provides ample space for a robust RAID strategy, enabling you to configure redundancy, performance, and capacity to match business needs. The diskless design is particularly advantageous for organizations that want precise control over drive choice, from enterprise-grade SAS drives to cost-conscious SATA options, ensuring that total cost of ownership aligns with your long-term IT strategy. In environments where data integrity and availability are paramount, the RX1222SAS works in concert with Synology’s DSM features—such as storage pool management, data scrubbing, and resilient volume creation—to deliver a scalable, reliable foundation for your data workloads.

For environments that value quiet operation and clean rack aesthetics, the RX1222SAS delivers a compact footprint with a professional appearance and straightforward deployment workflow. Its 2U rack footprint means it fits neatly into standard racks without occupying excessive space, while the enclosure’s design emphasizes airflow and cable management to maintain thermal stability as drive counts rise. When paired with compatible Synology NAS units, this expansion enclosure becomes part of a cohesive storage solution—one that scales with your business, supports data protection policies, and aligns with IT governance requirements. Whether you are archiving large media libraries, maintaining multi-site backups, or supporting a high-demand editing workflow, the RX1222SAS provides the scalable, dependable storage platform you need to keep data accessible and well organized.

How to install Synology RX1222SAS Drive Enclosure

  • Verify compatibility: Confirm that your Synology NAS model supports SAS-based expansion and has the appropriate PCIe or SAS interface to connect the RX1222SAS.
  • Prepare your rack: Schedule downtime if needed for maintenance, then mount the RX1222SAS in a standard 19-inch rack using the included rails or compatible mounting hardware.
  • Connect the expansion: Use the appropriate SAS connection from your NAS to the RX1222SAS. Ensure that cables are secure and routed to avoid interference with airflow or other equipment.
  • Install drives (optional): If you are populating drives at install, slide SAS or SATA drives into the 12 bays, ensuring proper seating and alignment with hot-swappable trays. If you are leaving the enclosure diskless, you can populate drives later as needed.
  • Power up and configure: Power on the RX1222SAS and your NAS, then open DSM to initialize the expansion by adding it to your storage pool or creating new volumes. Follow the storage manager prompts to assign RAID configurations, hot-spare drives, and storage quotas.
  • Monitor and manage: Use DSM to monitor drive health, set up alerts, configure data protection like snapshots or replication, and plan future expansion if capacity goals change.

Best DIY Bookshelf We've Gotten
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
Just finished putting this together and we're fully impressed. The product itself is exactly what it says on the tin, looks just like the photos. It takes a little bit of extra effort from your standard DIY bookshelf just because it has some extra decorative pieces, but we think it's worth it and that's one of the reasons we picked it out. Did have a MINOR bit of confusion since some of the decorative pieces weren't labeled, but they were easy to identify with the instruction manual. Which, let me just say, this is clearly a company who has seen the problems in the DIY furniture industry and has actually taken HUGE strides to make the whole experience easier on the customer and make the product sturdier. There are no bamboo pegs that might not even fit into their assigned holes, no weird turn-to-lock things that may are may not be tight enough to not unlock themselves, no ten different pieces of tiny hardware that barely look different from each other, and NO ALLEN WRENCHES. The entire piece can be put together with a regular screwdriver and a hammer (or just the screwdriver if you can't find the hammer and are determined enough, since you only need the hammer to tack on the cardboard backing); and because the structure's entirely put together with screws and because it's actually separated into two pieces, it makes the entire structure way more stable than your standard DIY bookshelf. The instruction manual is also not only EXCEEDINGLY, PAINSTAKINGLY clear about which way each piece should be facing and what hole you should be screwing it into, spelling it out for you when they can't just point it out on the diagram, or sometimes even doing both; it also comes with a little pre-measured spacer that you can cut right out of it to help you center the moldings on the shelves just right. And just as the icing on the cake, they also include a marker in the color of the laminate to fill in accidental scratches. We are extremely happy with this bookcase, and we'll be looking at Sauder products for future DIY furniture needs.

To be fair this is the worst side the other side is about an eighth of ...
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26", Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I used to work at big box store some twenty years ago and there were two selling points for Sauder furniture at the time. The furniture was 3/4 inch particle board and ease of construction. Well neither of those are the case any longer. I am putting this together and the L brackets that Sauder provides are of the adjustable variety. This lets one slide the two wooden pieces so to obtain a match on their edges. Well in theory, in reality one cannot slide them far enough so one has a 1/4 inch mismatched edge. On part H which is a horizontal trim piece. It is not long enough to cover the trim pieces edges that are below it in the vertical. Those edges are raw wood, but do not worry Sauder has been kind enough to include a brown magic marker so I will be able to cover up that raw wood. I included a photo of one side. To be fair this is the worst side the other side is about an eighth of an inch. And to be even more fair, there should not be any raw wood showing. It is not very sturdy either, the only thing that makes it from really wobbling is the fiber board backing at the rear of the bookcase. My expectations when I bought this piece of furniture was not that great. I wanted to buy a piece of furniture that was fairly easy to put together. I also wanted a piece of furniture that looked okay. This piece of furniture achieved neither one, I would have been better off going to a second hand furniture store and buying a bookcase there. Even if I had to refinish the second hand bookcase it would of been less hassle then this thing. Oh, Sauder I do not want to see a response saying please contact us at 1-800 whatever. When do most people put this furniture together? I would hazard to guess the weekend. When is Sauder customer service open? I can tell you it is not the weekend. If you are thinking of buying this, I would think twice.

Perfect buy
Color: Classic Cherry, Size: L:29.80" x W:12.99" x H:71.26"
I absolutely love this bookcase. It’s stable. It has the perfect color. It’s the perfect height not too tall, but definitely not short. And if it’s perfectly in the corner of my room, the only issue I had with this is the assembly process. Definitely don’t recommend you assembling it on your own. Definitely having someone there to help you assemble it. It’s definitely something I would do. It stores a lot of books, but definitely follow the weight capacity. I didn’t follow the weight capacity and now I have slightly bent shelves. It has good stability.The value is fair for how long it lasts because I still haven’t and it’s still standing.

Difficult to assemble, low quality, but looks nice
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
It looks nice when finished, but it's a major pain to put together. I've assembled a lot of DIY furniture over the years, but this was one of the more frustrating ones, mainly because of the unnecessarily difficult way the finishing slats need to be attached. Also the frame was very unstable during assembly. This bookcase is also not exactly sturdy even when finished. It's a low-quality product in all respects, really, except the nice way it looks. Value for money? meh. Color is nice.

Excellent Customer Service. Follow instructions.
Color: Classic Cherry, Size: L:29.80" x W:13.09" x H:71.26"
I LOVE the color of this bookcase. The bookcases at the big chain store generally cost around $100, so this is about what I was expecting. It's a nicer quality with thicker shelves than the big chain store bookshelves and I really wanted the cherry color, which, on this bookcase, is gorgeous. It was a bit difficult to assemble only because I asked for help from a male friend who insisted that we skip through the directions. We ended up getting a screw caught between two beams because he didn't want to sort out the screws like I ALWAYS do before assembling any furniture. Note: just breathe, relax and take your time and follow the directions, and if you ask for help from someone, give them a sedative, like a big dose of kava or something because it's going to take several hours. Once it's finished, though, it's really lovely. I filled it with books and so far, it's been fine. It is particle board with a finish, so if you scratch it, it's going to show. But, it comes with a brown color-coordinated marker so you can cover up minor scratches or flaws in the finish. I was a little surprised that the top of the bookcase is unfinished, but maybe a lot of bookcases are not nowadays. I wouldn't put it in a location where the top of it shows - like next to a staircase. The backboard is cardboard folded in half with the same cherry finish, which for me really wasn't an issue because I always fill my bookcases completely with books so the back doesn't really show. There are weight restrictions for each shelf, so make sure you pay attention to those - some shelves hold more weight than others. I plan to assemble the second one by myself now that I understand what's involved. I have to give five stars because customer service was so amazing. I didn't open the second bookcase for a long time, but despite the time that had passed, they still replaced a damaged beam very quickly, and even reshipped the beam a second time because I had given the wrong address. That was really amazing! Never had such a good experience with customer service before.
