The Synology RackStation RS1619xs+ 40TB 4-Bay NAS Enclosure (Enterprise Gold) delivers high performance and scalability for businesses that require a flexible, reliable, and efficient storage solution. This unit has four drive bays, each of which natively supports 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs. Should users need to expand the overall capacity of their RS1619xs+, the optional RX1217/RX1217RP expansion units offer an additional twelve drive bays.

The RackStation RS1619xs+ has a 1 RU form factor is powered by a 2.2 GHz Intel Xeon D-1527 Quad-Core processor, which will allow you to run multiple functions simultaneously. The 8GB of DDR4 ECC RAM will allow quick access to frequently used files and programmes and may also be upgraded to a total of 64GB by installing a 16GB module into the four DIMM slots. Also featured are two USB 3.0 Type-A ports which allow it to be connected to your Windows or Mac system. Network connectivity is achieved via the four Gigabit Ethernet ports with failover support, which help to provide redundancy in the case that a LAN connection malfunction occurs on one port. In addition, link aggregation, powered by four LAN ports, helps to increase connection speeds beyond the limits of a single network port or cable. If you're looking to expand this NAS, there is one PCIe 3.0 x8 slot that supports x8 cards and can be used to instal a 10GbE/25GbE NIC for fast data transmission. Furthermore, dual M.2 2280 slots support NVMe and SATA SSDs for caching.

The RackStation RS1619xs+ runs on the DiskStation Manager (DSM) operating system, which helps simplify managing your NAS, as well as accessing and sharing data. A variety of RAID modes are supported, which help provide users with data redundancy, speed, or a combination of both. Supported RAID modes include RAID 0, 1, 5, 6, 10, and Basic, each of which offers redundancy, performance, or a combination of both. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilised. Sequential read speeds are supported up to 1527 MB/s.

Synology has engineered the RackStation RS1619xs+ to be energy efficient. Not only does it offer two 40 x 40mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard drive hibernation to further minimise power consumption and operational expenses. The RackStation RS1619xs+ is equipped with dual redundant 150W power supplies that operate using 100-240 VAC at 50/60 Hz. Included is an accessory pack and two AC power cords. Protection is provided by a limited 5-year hardware warranty.
