Fixed an issue where the throughput in Resource Monitor might not be displayed correctly when the system network traffic or the throughput of disks or volumes was heavy. On a newly installed version of DSM, file rename and deletion log events for SMB will be enabled by default. Fixed an issue where Finder might stop responding when users search for content within mounted folders on macOS Big Sur 11.1 and 11.2. Fixed an issue where enabling the "Collect debug logs" option for SMB might result in excessive system space usage. Added a new Fast Repair mechanism to reduce the time needed for RAID repair based on storage usage and thus reduce the time of RAID degradation.

For users with the DS918+, it’s a marginal upgrade if you’re just using it for file sharing purposes. The faster processor will help with things like transcoding media, and VMs also run a bit better provided you’ve add in an extra RAM module.Fixed an issue where certain models might experience abnormal shutdown after updating to DSM 7.2.1. Fixed an issue where certain models might experience unsuccessful replication with Snapshot Replication after updating to DSM 7.2. Fixed an issue where iSCSI services may be unstable when the host is too busy or when users disable iSCSI targets and ending sessions simultaneously. The following DDNS providers are removed from the service provider list at Control Panel > External Access > DDNS:

Creating M.2 storage pools requires the use of Synology-verified SSDs, which are rigorously tested under extreme temperature conditions. Thermal parameters for SSDs and NAS units are fine-tuned to ensure optimal management of thermal conditions under I/O-intensive environments. ( Learn more) Fixed an issue where enabling OVS might affect the performance of 10Gb network interface controllers.Storage figure calculated based on a RAID 5 configuration. Total storage capacity may vary depending on hard drives used and RAID configuration.

Improved fan speed control based on the Synology network interface card temperature for 19-series and newer models.

Fixed the issue where a DS920+ or DS720+ might not enter hibernation when its connected expansion unit has entered deep sleep. Added the Auto Repair feature to automatically run a RAID repair when a malfunctioned drive is replaced with a healthy one in the same drive slot. Plus Series: RS2416RP+, RS2416+, DS916+, DS716+II, DS716+, DS216+II, DS216+, DS1817+, DS1517+, RS2818RP+, RS2418RP+, RS2418+, RS818RP+, RS818+, DS1618+, DS918+, DS718+, DS218+, RS1219+ Added the Greenwich Mean Time (GMT+00:00) time zone option at Control Panel > Regional Options > Time. Fixed an issue where there is a slight possibility that the SMB service might be shortly disconnected the moment users apply SMB setting modifications.

The URLs used by DSM when updating or running services have been modified. Please read this article and make sure that your firewall rules are configured appropriately. Updated C2 Identity Edge Server to version 1.52.0-0186 to ensure its availability and functionality. DDSM is incompatible with DSM 7.0. To continue using DDSM, you should retain the current DSM version. To update to DSM 7.0, please delete DDSM first. Fixed an issue where file access failed due to errors during soft link creation in Btrfs file systems. Surveillance Station must be updated to version 9.0.1- 7673 or above to be compatible with this update.The Synology DS920+ will vary on performance based of course on your drive and RAID setup, as well as whether or not you’re using the NVMe slots for caching. Our test setup used two Seagate 4TB drives in a RAID 1 array, without caching. Network file copy of a folder with multiple file sizes peaked at about 127MB/s when copying to the NAS, and about 134MB/s when copying from it. series: RS2818RP+, RS2418RP+, RS2418+, RS818RP+, RS818+, DS1618+, DS918+, DS718+, DS418, DS418play, DS418j, DS218+, DS218, DS218play, DS218j, DS118 Added support for memory cache mirroring across controllers for better data consistency on SA3200D. Supports creating volumes of up to 1 PB in Btrfs (Peta Volume) format on the XS/XS+, SA (SA3200D excluded), and FS-series models. ( Learn more)
