Designed to provide space-sensitive deployments for business and IT enthusiasts, the RackStation RS1221+ 8-Bay NAS Enclosure from Synology is equipped to handle heavy workloads in data-intensive environments, with sequential read speeds of up to 2315 MB/s and sequential write speeds of up to 1147 MB/s. This unit has 8 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 RS1221+, the optional RX418 expansion unit offers an additional four drive bays. This model is powered using a single 250W power supply.The RackStation RS1221+ is powered by a 2.2 GHz AMD Ryzen V1500B Quad-Core processor, which will allow you to run multiple functions simultaneously. The 4GB of DDR4 ECC RAM will allow quick access to frequently used files and programs and may also be upgraded to a total of 32GB by installing a 16GB module into each of the SO-DIMM slots. Also featured are two USB 3.0 Type-A ports and one eSATA port. 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/x4 slot that can be used to create an NVMe M.2 SSD cache, add a 10GbE network card, and more.The RackStation RS1221+ 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, Basic, and Synology Hybrid RAID. For those who do not require a RAID, JBOD is also available, allowing each drive bay to be individually utilized.Synology has engineered the RackStation RS1221+ to be energy efficient. Not only does it offer two 80 x 80mm fans to help keep the system running cool, the server supports numerous scheduled power on / off cycles and hard-drive hibernation to further minimize power consumption and operational expenses. The RackStation RS1221+ operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, an AC power cord, and a C13 to C14 power cord. Protection is provided by a limited 3-year hardware warranty.
