FAQs

Q1: What is the maximum memory supported?
Up to 32 GB ECC DDR4 (2 × 16 GB modules); one 4 GB module pre-installed.

Q2: Can I install non-Synology ECC RAM?
Some third-party modules may work, but Synology recommends using certified RAM to maintain support and compatibility.

Q3: Do the NVMe slots support storage volumes?
No, the two M.2 slots are for SSD caching only—not for hosting storage volumes.

Q4: Is this NAS suitable for virtualization and Docker?
Yes—with upgraded memory and SSD cache, it reliably supports multiple VMs and container workloads.

Q5: How noisy is the unit during operation?
Extremely quiet under normal settings—fan noise levels around 22 dB(A).

Q6: Does it support media transcoding (e.g., Plex)?
It supports direct video playback, but lacks hardware transcoding support; high-resolution transcoding may be limited.
