FAQs
Q1: Can I use this card for data storage?
No. The M2D20 is designed specifically for SSD caching, not as a standalone storage volume.
Q2: Is it compatible with SATA M.2 SSDs?
No. It only supports NVMe SSDs (M key or B+M key, depending on slot).
Q3: Which Synology NAS models support this card?
Models like DS1621+, DS1821+, RS1221RP+, and others with available PCIe slots. Always confirm on Synology’s compatibility list.
Q4: Can I use just one SSD in the M2D20?
Yes. You can use a single SSD for read cache or two for read-write cache.
Q5: Is active cooling required?
The included passive heatsinks provide sufficient thermal dissipation for most use cases.
Q6: How do I configure SSD caching in DSM?
Use Storage Manager in DSM to set up read or read-write caching with step-by-step guidance.
