Having recently reviewed the Synology DS1010+ NAS server, and coming to a more than satisfactory conclusion taking into account performance, practicality and ease of use, today’s review focuses on an expansion unit  compatible with both the DS1010+ and DS710+ units.

In keeping with the typical Synology style, the packaging consists of cardboard box stamped with just the Synology logo and product name. The accessory bundle has also been stripped back from the DS1010+ with the DX510 only intended for expansion: a few screw packets for HDD installation, user manuals, power cable and an eSATA cable for connecting the unit to the main NAS server.

The DX510 aesthetically is a direct replica of the DiskStation 1010+ NAS server featuring a shiny black front fascia and matte black panelling. A number of status LEDs occupy the upper part of the front panel labelled RAID, eSATA, STATUS and ALERT.

Indeed, the DX510 compliments its target market - small and medium businesses – with its plain black styling and overall appearance.  

The hard drive trays are in vertical alignment and are compatible with both 2.5” and 3.5” SATA drives offering up to 10GB of storage in total. As with other Synology NAS products, the storage can be configured in a selection of RAID configurations including basic, JBOD, RAID 0, 1, 5, 5+Spare and 6. Naturally, managing the device is done through Synology’s DiskStation Manager – the latest version being 2.3 offering a wide variety of applications and features as seen in our DS1010+ article.

Installing a hard drive simply involves pulling out one of the trays, screwing the hard drive into place and then replacing the tray to the device; pushing the tray back in fully connects both the SATA and power connections without needing to fiddle with any cables.

Flipping the DX510 around reveals vents for the dual 80mm cooling fans screwed to the rear of the device plus the power connection, Kensington lock and eSATA port. Using the bundled eSATA cable allows the expansion unit to be connected up to the main NAS server and should ensure a reliable connection. eSATA throughput speeds are also far in excess of USB limited at standard SATA speed: 3Gbps so as to maximise data throughput.

Conclusion

The DX510 expansion unit does exactly what is says on the tin: offer volume expandability with an additional five hard drive slots available for significantly increasing storage size by up to 10GB.

The hot swappable hard drive design and single cable connection ensure the DX510 is incredibly simple to use and perfect for backing up data. For a business NAS setup, the DX510 really is the perfect accompaniment to the DS1010+ if you’re looking to increase the storage capacity but it does came at a price... just over £380 inc. VAT.

Still if you’re willing to spend in that sort of price range, the Synology DX510 is an ideal storage expansion unit for either the DS1010+ or DS710+ NAS servers.
