Synology

Synology Inc. (Chinese: 群暉科技; pinyin: Qúnhuī Kējì) is a Taiwanese corporation that specializes in network-attached storage (NAS) appliances. Synology's line of NAS is known as the DiskStation for desktop models, FlashStation for all-flash models, and RackStation for rack-mount models. Synology's products are distributed worldwide and localized in several languages. Synology's headquarters are located in Taipei, Taiwan, with subsidiaries located around the world. In 2018, product review website Wirecutter described Synology as a "longtime leader in the small-business and home NAS arena," albeit still a newcomer in the field of Wi-Fi routers. For years, Synology NAS units supported third-party hard drives, giving users the freedom to choose from various brands and capacities. That changed in 2025, when Synology started locking its NAS devices to only accept Synology-branded hard drives, effectively ending their long-standing tradition of open drive compatibility. With the release of DSM 7.3 in October 2025, Synology reversed its lock on only allowing NAS devices manufactured in 2025 (i.e. - DS425, DS225, etc) to use Synology-branded hard drives (HDD) and once again third party hard drives can be used, but M.2 drives are still locked to Synology's own brand.
