Synology Dual M.2 SSD Adapter Card for Extraordinary Cache Performance

Elevate your NAS performance with the Synology Dual M.2 SSD Adapter Card, designed to slash random I/O latency and turbocharge cache acceleration. The M2D18 provides two M.2 NVMe SSD slots that turn your Synology NAS into a powerhouse for workloads such as photo indexing, rapid file search, virtualization environments, and demanding database and media tasks. With its compact PCIe expansion design, this adapter enables extraordinary cache performance without compromising system stability or reliability.

• Dual M.2 NVMe SSD slots dramatically boost NAS cache capacity, enabling larger and faster cache pools that improve read and write operations across intensive workloads.
• Significant reduction in random I/O latency translates to snappier file searches, quicker photo and media indexing, faster boot storms for virtual machines, and smoother virtualization tasks.
• Designed for seamless integration with compatible Synology NAS models that support PCIe expansion, providing a straightforward upgrade path for existing storage environments.
• Optimized cache acceleration with two-drive support, allowing flexible caching strategies and improved data access patterns for multi-user environments.
• Enhanced workload efficiency reduces wear on main storage pools by offloading frequent cache operations to the high-performance NVMe SSDs, improving overall NAS responsiveness and uptime.

how to install Synology Dual M.2 SSD Adapter Card

• Power down your Synology NAS and unplug from the power source. Ensure you follow safety procedures and discharge any static electricity before handling components.
• Open the NAS chassis access panel to locate the PCIe expansion slot. Verify there is an available PCIe slot that supports an add-on card.
• Install the M2D18 adapter card into the PCIe slot, aligning connectors carefully and pressing firmly until it sits securely in place.
• Insert two NVMe M.2 SSDs into the two slots on the adapter card. Confirm that each drive is fully seated and that there is proper clearance for airflow within the chassis.
• Reconnect power, boot the NAS, and use DSM (DiskStation Manager) to configure caching. In Storage Manager, enable SSD cache and select the M2D18 drives as cache devices, choosing the appropriate read/write cache mode based on your workload.

Frequently asked questions

• What is the Synology M2D18 Dual M.2 SSD Adapter Card used for?
• It adds two M.2 NVMe SSD slots to compatible Synology NAS models via PCIe, enabling accelerated SSD caching to reduce latency and improve performance for demanding workloads.
• Which NAS models are compatible with the M2D18?
• Compatibility depends on whether the NAS model includes an available PCIe expansion slot and supports SSD caching. Check your model’s hardware specifications and DSM guidance for caching support.
• Do I need to buy SSDs separately?
• Yes. Two compatible NVMe M.2 SSDs are required to take full advantage of dual-cache operation. The NAS and DSM software will manage caching once installed.
• Can I use SATA M.2 SSDs with the M2D18?
• Typically, the M2D18 is designed for NVMe PCIe M.2 SSDs. SATA-based M.2 drives are not recommended for this caching adapter in most configurations.
• What benefits can I expect from using this adapter?
• Expect reduced random I/O latency, faster indexing and searches, improved virtualization performance, and smoother operation during cache-heavy tasks, especially in multi-user and media-rich environments.
