M2D18

Dual M.2 SSD adapter card for extraordinary cache performance

Elevate Your Storage Performance To the Next Level

Designed to supercharge your NAS I/O performance, Synology M.2 SSD adapter M2D18 significantly reduces random I/O latency, benefiting applications such as photo indexing, file search, and virtualization environments.

The dual M.2 SSD slots support both SATA and NVMe SSD, meaning higher SSD read/write caching and more primary drive bays reserved for data storage.1 Attachable heatsink accelerates thermal dispatching of M.2 SSD and assures system stability with excellent performance. Its flexibility in supporting 2280/2260/2242 form factors and meeting various SSD options saves you from vendor lock-in.

Notes:

  1. Please choose endurable SSDs designed for mission-critical workloads.
    Since the longevity of an SSD is limited to a finite number of writes, please make sure you use higher endurance SSDs in I/O-intensive environments to prevent potential data loss.
