It has its own data control backplane that works independently of the main unit, and allows each disk inside to be individually addressed or built into volumes, queried for diagnostic status or temperature, and perform any of the functions of a locally attached disk. The main NAS unit also has full control of the expansion unit's fan speed, power state, LEDs and power button function, so it really is just a good as flexible as having a NAS with more drive slots.The build quality is just as solid as my DS716+, and the dimensions match up so they look natural sitting next to one another - the DX513 is noticeably deeper, however, and the side bezels are a little thicker.It has an internal power supply that connects with a standard and included IEC three prong cable( which differentiates it from the 716+, which comes with an external switching-type "brick") - this is a nice feature that creates less clutter and alleviates some of my fear of accidentally disconnecting it.It uses the same toolless, screwless drive sleds as the DS716+. Mounting laptop-profile drives requires screws, and it comes with all the screws that you'd need to put laptop drives in all fives bays at once (if that were for some reason a thing you actually wanted to do), but most people shouldn't need to touch a screwdriver in the setup.It's also impressively quiet, and I'm comfortable having it set up in my bedroom without it being a distraction - I've been running it for months and the fans have never spun above a low, almost inaudible level.Altogether, if you already have a Synology NAS and you want more drive bays, I'd highly recommend it. If you're planning to buy a Synology NAS for the first time, it would be feature equivalent but more cost effective to buy a unit that already has the capacity you need. ### ⭐⭐⭐⭐⭐ VERY powerful and easy to use NAS *by C***Y on April 6, 2013* I used to run a Windows Home Server setup, and this is MUCH easier to work with and add drives to - especially after Microsoft removed the Drive Extender feature in WHS 2011. I highly recommend Synology devices to all my friends - and even if this unit is out of your price range, there are lower cost units that don't hold as many drives that perform just as well.I'd say the only possible downside (if you would even call it that) is the amount of time it takes the unit to ingest additional drives. I have 12 drives in the unit currently (Using the DX513 expansion module as well) and it takes about 24 hours to add an additional 3TB drive. BUT, this is a ONE TIME ordeal and the system is accessible and usable the entire time. Other reviewers have mentioned the long delay, but they aren't understanding what the system is doing - It's formatting it, then running a consistency test/testing the drive for errors, and then migrating+balancing data from all the other drives across the new array.Overall, I can't say enough good things about this unit. - I would HIGHLY recommend pairing this system with the WD Red NAS drives - they cost a little bit more, but the 3TB version can usually be had for $140-160 and they are worth every penny. ### ⭐⭐⭐⭐ A great workhorse *by D***S on November 8, 2015* this is a great unit, I have been running it with one of the expansion bays for nearly three years. It did give me a few scares at times when it stops working and would not turn on. Then i realised that it was getting too hot and I had to create proper ventilation for it, now it works like a charm. I will be looking to upgrade once the new Intel processors are out. --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/1211830-synology-5bay-expansion-unit-dx513-diskless-black](https://www.desertcart.co.uk/products/1211830-synology-5bay-expansion-unit-dx513-diskless-black) --- *Product available on Desertcart Great Britain* *Store origin: GB* *Last updated: 2026-04-23*
