Its CPU is a 2.6 GHz AMD Ryzen R1600 Dual-Core with a burst frequency of up to 3.1 GHz, and its 4GB of DDR4 RAM, which can be upgraded to 32GB, allows frequently used files and applications to be quickly accessed. This NAS is capable of sequential read speeds up to 625 MB/s and sequential write speeds up to 559 MB/s.

Also featured are two USB-A 3.2 Gen 1 ports that allow it to be connected to external storage or other USB devices, an eSATA port for the DX517 expansion unit, and network connectivity is achieved via the dual integrated Gigabit Ethernet ports that support link aggregation and failover, allowing your stored data to be shared with users throughout the network. For those who require RAID support, the DS923+ 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 DS923+ is engineered to be energy efficient and its dual 92 x 92mm fans to help keep the system running cool at all times. The server supports numerous scheduled power on/off cycles and hard drive hibernation to further minimize power consumption and operation expenses.

Q: 4. I found it really hard to look for footage inside the nas because it’s slow, what should I do to increase the speed? Already installed two fast nvme.

A: NAS performance can be linked to many factors, such as drive speed, the type of RAID you are using, and the speed of your local network. If you have your DS1522+ configured in RAID 1 or JBOD, consider using a faster configuration such as RAID 0 or 5. If the NAS is connected to a network switch, make sure that it is using a gigabit port. If it is connected directly to your router, make sure that your local network is operating with appropriate speed and bandwidth and that the computer you use for editing is using a wired Ethernet connection instead of WiFi.
