Know before you buy
Yes, the DS425+ comes with 2GB of DDR4 memory pre-installed and can be expanded up to a maximum of 6GB to improve multitasking performance.
The two M.2 slots are designed for NVMe SSDs, which act as a cache to significantly speed up random I/O performance and reduce latency for frequently accessed data.
To take full advantage of the 2.5GbE networking, your router, switch, and the computer or device you are connecting from must also support 2.5GbE speeds. If your network equipment is limited to 1GbE, the connection will default to that lower speed.
You can use either 3.5-inch HDDs or 2.5-inch SATA SSDs in the four main drive bays. While you can mix drive types across different bays, it is generally recommended to use identical drives within a single RAID volume for optimal performance and reliability.
The DS425+ supports a maximum raw storage capacity of up to 108TB, depending on the size of the drives you install in the four available bays.
The unit supports a wide range of configurations including RAID 0, 1, 5, 6, 10, JBOD, and Synology’s proprietary Synology Hybrid RAID (SHR). SHR is often recommended for home and small office users as it allows for more flexibility when mixing drives of different sizes.
