Improved management experience
New Storage Manager makes it easier to troubleshoot, monitor, and maintain your Synology NAS.
Graphic overview
Identify the source of drive problems at a glance. Avoid accidentally removing or replacing the wrong drives.
Manage available drives
Wizards automatically guide users through the steps to set up available drives.
Volume usage details
View exactly how much storage individual DSM services use on your Btrfs volumes.
Enterprise class storage features
Maintenance and repair need not affect performance or uptime with new advanced drive replacement options.
Seamless manual drive replacement
Clone an old drive to a reserved spare, seamlessly switch to the clone, and remove the old drive without ever degrading the storage pool.
Predictive auto drive replacement
Let DSM automatically clone drives to an available hot spare when they reach critical or failing status and switch without RAID rebuild time.
Faster RAID rebuild
The new Fast Repair function restores only active storage capacity, so RAID arrays spend less time in a degraded state.
Petabyte Volume support1New in 7.0.1
Create up to 1 PB volumes for data archives, video management systems (VMSs), or file servers requiring bulk storage.
Flash volume deduplication2New in 7.0.1
Select models support volume-wide deduplication to optimize VM and container storage by removing duplicate data on all-flash arrays. Deduplication can be run manually or as a scheduled task.
Safely eject storage pools
Safely ejecting storage pools and removing devices on expansion units leaves unrelated services online and unaffected.
SSD cache enhancements
Flexible online management
Create and remove SSD cache without interrupting system services.
SSD Cache Advisor
Monitors I/O operations and provides more accurate storage capacity recommendations.
Rapid write-back
Faster data write-back speeds up synchronization from SSD cache to HDD and automatically protects cached data.
Btrfs metadata caching
Store all Btrfs metadata to your SSD cache to speed up response and accessing times for all files.
