The Synology DiskStation DS2015xs is an 8-bay, tower-chassis NAS with a maximum internal capacity of 48TB that can be deployed in tandem with Synology's 12-bay DX1215 expansion shelf for a total raw capacity of 120TB.

Upgradable to a total of 120TB of storage capacity and 8GB of system RAM; Proven DiskStation Manager operating system and management interface with a robust ecosystem of built-in and optional applications; Passively cooled processor reduces power requirements and possible points of failure

Lackluster performance compared to the Synology DiskStation DS1815+ across most benchmarks

In order to keep testing consistent across all 8-bay units, we performed all our expansion / rebuild testing as well as power consumption evaluation with the unit configured in RAID-5. The disks used for benchmarking (OCZ Vector 4 SSDs) were also used in this section.

Marketed as a medium-sized business solution, the 8-bay DiskStation DS2015xs from Synology is a very scalable NAS appliance which, when teamed with an optional 12-bay expansion unit, has an impressive raw capacity of 120TB.

Be advised, you can not transcode videos on this model. Synology seems to have chosen a less powerful processor and provided the 10Gbt LAN ports. I'm returning this and getting the DS1815+.

Synology's DS2015xs makes 10GbE storage networks even more affordable

Very good value; dual 10GbE SFP+ ports; Good NAS performer; Feature-rich DSM software

10GbE transceivers increase price; Alpine SoC delivers poor iSCSI write performance

I am really the wrong person to review this item to fully give a true technical opinion. After a lot of research, I decided to go with this item which if you look at the specs is total overkill for my requirements, allowing 200 people to connect to it when I have it just for myself but I am not your...
