Synology 4 Bay NAS DiskStation DS920+ Description
Synology NAS DiskStation DS920+ is an ideal network-attached solution created to improve productivity and data management. As your data grows, you can start small and use the Synology DX517 to increase storage capacity with the DS920 scalable + 's storage design.
With its two integrated M.2 SSD slots, which support Synology SSD Cache technology, you can cut the random I/O response time by 20 times compared to mechanical drives without taking up any front drive bays. For increased storage capacity, use the Synology DX517 and add five more drives. Users of DS920+ have access to a variety of backup options for on-premises and cloud environments. On compatible NAS models, backing up and restoring data is simple and completely cost-free.
The Btrfs file system on the DS920+ has been enhanced by Synology to provide you with excellent performance, high reliability, and support for cutting-edge storage technologies that satisfy the demands of modern business.
Streamline your Data Management Experience:
The Synology DS920+ is a strong 4-bay desktop NAS with sequential read and write throughput of over 225 MB/s3. It benefits computing-intensive applications, increasing the speed of Synology Drive and Moments by an average of 15% and increasing the efficiency of Web PHP response by approximately 130% over its predecessor, making data management efficient and simple.
On-site Synching and Collaboration Solution:
The DS920+ includes Synology Collaboration Suite, a productivity and file sharing solution that powers team collaboration while leveraging the benefits of the private cloud to fully control data and prevent data leaks via HTTPS support, a built-in firewall, and multiple IP and account intrusion auto-blocking mechanisms.
Automated Video Surveillance System:
The Synology Surveillance Station allows the DS920+ to function as a full-featured video surveillance system. Simply connect network-connected cameras and you can immediately monitor live feeds, play back recordings, and receive instant event alerts. Unlike security cameras that require a monthly cloud storage subscription, all of your recordings are stored on the DS920+ and are completely under your control.
Protecting and Running Virtual Machines:
Synology Virtual Machine Manager (VMM) is a user-friendly hypervisor application that allows users to easily create virtual machines and run operating systems such as Windows®, Linux®, and Virtual DSM. Users can create a cluster environment with multiple Synology systems while maintaining the ability to scale out online and migrate virtual machines for load balancing and resource allocation using VMM.
Virtual Machine Manager (VMM) Pro licenses:
Disaster recovery features such as replication, instant snapshot, cloning, restore, and failover help you fully protect each virtual machine and safeguard your digital assets at no additional cost. VMM Pro licences provide access to advanced features such as remote storage migration, remote replication, high availability, and live migration, allowing users to further reduce the risk of service downtime and manage IT resources with maximum flexibility.
