Synology announces new 8-bay NAS, the DS1821+ — Apple World Today

The DS1821+ provides eight drive bays with the ability to expand to 18 with the use of expansion units. Powered by Synology DiskStation Manager (DSM), in addition to standard RAID arrays, Synology Hybrid Raid (SHR) allows users to create arrays using odd-sized drives while still maximizing the storage potential of the array. This enables older drives to be serviceable, without requiring an upfront commitment to only installing drives of the same capacity.
DSM also provides a means of upgrading storage capacity after the device has been set up. You can add in a new drive and expand your array. RAID options can similarly be upgraded, from a lower protection level to a higher one, such as from SHR-1, one drive redundancy, to SHR-2, two drive redundancy.

To protect IT infrastructure, Active Backup Suite allows centralized backup from Windows and Linux-based PCs and servers, virtual machines on VMware and Hyper-V hypervisors, along with Google Workspace and Microsoft 365 SaaS platforms. 

Snapshot Replication creates schedulable point-in-time recovery points, allowing ways to roll back unintended file edits or even ransomware encryption for both Shared Folders and for iSCSI LUNs. Synology Hyper Backup enables schedulable protection to keep your data backed up to another Synology NAS, a USB drive, Synology C2 cloud storage, and other public cloud providers.
