How interesting do you think of Synology DX vs. Synology DX? They are pretty similar, but still, they also have differences that affect the final choice you make.

In case you want to expand its storage, it is an excellent idea for a great solution. Quickly said, Synology DX is considered a flexible solution that serves as a local backup destination and support the volume expansion on the fly. As for its online volume expansion, it should be managed from the DiskStation Manager. Then, the additional bays will be ready for use.

Never dropped a single disk or had to rebuild. Pros: Basically plug and play Cons: Not the cheapest NAS in the world, but you get what you pay for. Also, documentation is erroneous see "Other Thoughts". Overall Review: If you have a compatible device that's full, then this is a no-brainer.

Yes, it may be expensive if you consider it to be just another set of slots and a power cord, but that's selling the architecture short. Price, not so much, but if you're looking to save money, you're not looking at Synology devices anyway.

At least in my experience, the cable simply didn't go that way; I had to insert it with the "Synology" logo facing up on both the master device and the DX Worked just fine. This is intentional, near as I can tell: just put at least one disk in the DX and power it on, and it'll stay powered on and the device and the disk s will show up in DSM on the master device just fine. Also, kudos to Synology support for getting back to me so quickly. Synology is the best, and you get what you pay for.

Pros: Connect the power cable and the esata cable and your done. That simple? Loaded my box with 5xWD Red 2TB and purrs like a kitten using very little power, little to no noise and zero issues.

Or put it like this. I can build a rack box for 5 drives cheaper. Overall Review: I bought this, then filled it with 5 drives and immediately expanded my SHR volume and dumped data on it. I'm still in the process of moving all my data offsite so I can blast the volume and rebuild the whole thing with new drives, so I can't yet tell if I got a Lemon that will destroy drives or if I got bad drives.

If you can predict about 4 years down the road from how many drives you think you want now, just buy a bigger base unit and then you won't need to bother with the expansion units. Synology is great in that you can dynamically add drives to the raid volumes.

Even in a RackStation unit, you don't need to fill all the bays at the get-go. Pros: Easy Setup. Even though the drives I was using were on the Synology approved drives list they caused most of the trouble I was having with this unit and once I figured that out things went much better.

I assume it has something to do with the esata connection.

Cons: Poor error reporting, it would have saved me a lot of trouble if I had gotten some indication of what was going on instead of just locking up or telling me the volume was crashed. Overall Review: Once the drives issue was figured out, seems stable although still a bit slow on the volume creation functions.

Cons: Piece of junk. Keeps telling me fan has failed, even though they are both running. Slows down volume creation to a crawl. Crashes the main unit connection lost reboot. Overall Review: So far I'm not impressed at all with this unit. I Suggest simply buying a larger main unit to begin with. Being able to add storage on later is a nice idea but poor execution in this case.

Top positive review. Reviewed in the United States on September 5, The price Synology wants for these expansion units is excessive. I can only recommend it if you can get it on sale, which I did. Otherwise you are better off buying another complete NAS.

With each NAS you get 2 camera licenses included, so that is another negative for the expansion unit. I've also noticed a performance drop for data going to the expansion unit. So in summary I think this is only practical if you simply must have some extra drives attached to your main unit, either in a busy office where you don't want to change anything or some similar reason.

Just be aware that extending your volume onto the expansion is risky. Always have backups! Top critical review. Throw away equipment! Reviewed in the United States on July 25, I have been using Synology equipment since I have gone through many bugs, deficiencies, enhancements and software updates during that time. As with any hardware platform driven by software there is inevitably these kind of challenges but what I didn't expect was to be forced to throw away equipment in less than 4 years due to Synology's approach to hardware repair.

If you encounter a hardware issue with Synology hardware after the warranty period you will have no way of getting it repaired by this company and will have to throw it away! I made this inquiry to Synology: "Hi do you have a repair service for this unit? Unfortunately it is just outside the warranty period.Make informed decisions with expert advice. Learn More.

Or put it like this.With the ever-increasing nature of enterprise-level storage demands, administrators not only have to focus on fulfilling current needs, but also keep an eye on scalability and future-proofing.

Replacing or upgrading infrastructure can often be costly and time-consuming, to say nothing of inconvenience or lost opportunity. The RXRP submodel also features two power supply units, ensuring that if one PSU fails, the unit automatically continues drawing power to prevent downtime and loss.

It features the same energy-saving and local backup you would expect from its counterparts, but like the RX is lacking in an option for a redundant power submodel. The DX provides for an additional 2 bays of expansion, while the DX provides 5. One of the main advantages of the Synology expansion units is they operate exactly how a standard JBOD shelf would in an enterprise environment.

As soon as the expansion unit is connected the HDDs or SSDs become readily visible as if they were inserted into the main unit itself.
