FAQs

Q1: Can I upgrade the memory beyond 2 GB?
Yes, you can increase RAM up to 6 GB by adding a second DDR3L SODIMM (maximum supported).

Q2: Is this NAS suitable for HDDs or only SSDs?
While it supports 2.5″ HDDs, the DS620slim is optimized for SSD performance and works best when populated with SSDs.

Q3: Does it support multiple RAID types?
Yes—it supports SHR, RAID 0/1/5/6/10, JBOD, and Basic configuration options.

Q4: What network performance should I expect?
Dual Gigabit ports support aggregation for higher throughput, but max real-world speeds are capped by Ethernet (~100 MB/s).

Q5: Can this handle Plex or Docker tasks?
Yes for direct-play usage and lightweight container workloads. Plex transcoding and heavy multi-client usage may be limited by CPU and memory.

Q6: Is the unit noisy during operation?
No—the DS620slim is designed for quiet operation (~20.5 dB(A)), and many users upgrade to ultra-quiet Noctua fans for near-silent use.
