Built with a quad-core processor, an AES-NI hardware encryption engine, and Btrfs file system support, the DiskStation DS1621 6-Bay NAS Enclosure from Synology is a high-performance system designed to store and protect critical assets, while also offering storage scalability so you can start small and expand as your data grows. Boost storage performance by installing dual M.2 2280 NVMe SSDs for high-IOPS system caching, or enhance network speeds by adding a 10GbE SFP or RJ45 NIC to the PCIe 3.0 x8/x4 slot. This NAS is equipped with six drive bays that are capable of natively supporting 3.5" SATA hard drives, as well as 2.5" SATA hard drives and SSDs, for data storage. Using its six drive bays, this NAS will allow you to store and share many files, including videos, music, photos, and documents with up to 2048 user accounts and 1000 maximum concurrent connections.





The DS1621 runs on the Synology DiskStation Manager (DSM) OS, which is a browser-based operating system that helps to simplify managing your Synology NAS. Its CPU is a 2.2 GHz AMD Ryzen V1500B Quad-Core and its 4GB of DDR4 ECC RAM, which be upgraded to 32GB, allows frequently used files and applications to be quickly accessed. The NAS is capable of sequential write speeds of up to 2300 MB/s, as well as 110,000 4K random read IOPS.





Also featured are three USB 3.2 Gen 1 Type-A ports, plus two eSATA ports for storage expansion, and network connectivity is achieved via the four Gigabit Ethernet ports, allowing your stored data to be shared with users throughout the network. For those who require RAID support, the DS1621 supports RAID 0, 1, 5, 6, and 10, 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 DS1621 is engineered to be energy efficient. Not only does it offer two 92 x 92mm fans to help keep the system running cool, it supports numerous scheduled power on/off cycles and hard drive hibernation to further reduce power consumption and operation expenses.





The Synology DiskStation DS1621 6-Bay NAS Enclosure operates on 100-240 VAC at 50/60 Hz and includes an accessory pack, a power cord, and two RJ45 LAN cables. If you need to expand its storage, the DS1621 can be connected to two DX517 expansion units. Protection is provided by a limited 3-year hardware warranty.Designed for use in 1-8 bay NAS environments within home, SOHO, and SMB environments, the 12TB IronWolf 7200 rpm SATA III 3.5" Internal NAS HDD (CMR) from Seagate is built to withstand 24x7 operations, or 8760 hours per year. This 12TB drive has been equipped with a SATA III 6 Gb/s interface, a rotational speed of 7200 rpm, a 3.5" form factor, and a 256MB cache, providing users with an ample storage capacity and data transfer speeds of up to 210 MB/s. This IronWolf hard drive also has an MTBF rating of 1 million hours, 600,000 load/unload cycles, 1 in 1015 non-recoverable read errors per bits read, and a workload rate of up to 180TB per year.
