Designed for home and personal users who need to store and share photos, videos, and documents, the DiskStation DS220j 2-Bay NAS Enclosure from Synology is an entry-level NAS for personal cloud storage that delivers an intuitive user interface and safe data protection approaches for easy digital asset backups from computers and mobile devices at no additional cost. It is equipped with two drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs with a drive bay adapter. It is capable of read and write speeds of up to 112 MB/s.

The DS2120j runs on Synology DiskStation Manager (DSM) OS, which is a browser-based operating system which helps to simplify managing your Synology NAS. Its CPU is a 1.4 GHz Realtek RTD1296 Quad-Core and its 512MB of DDR4 RAM allows frequently-used files and applications to be quickly accessed. Also featured are two USB 3.0 Type-A ports which allow it to be connected to external drives or other peripherals, and network connectivity is achieved via the integrated Gigabit Ethernet port, allowing your stored data to be shared with users throughout the network. Data may also be made remotely available through the free iOS and Android applications. The DS220j is also able to function as a multimedia solution for management, streaming, and playback.

For those who require RAID support, the DS220 supports RAID 0 and 1, as well Synology Hybrid RAID and Basic RAID, each of which offers performance, data redundancy, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.

The DS220j is engineered to be energy efficient. Not only does it offer a 92 x 92mm fan to help keep the system running cool at all times, its noise dampening design of 18.2 dB(A) makes for quiet operations. The server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimize power consumption and operation expenses.
