QNAP QM2-2S-220A

Overview

The QNAP QM2-2S-220A is a PCIe Gen2 x2 expansion card designed to add two M.2 SATA SSD slots to compatible QNAP NAS devices or Windows and Linux workstations. It enables faster file transfers, backups, and database operations by connecting SSDs directly to the PCIe bus. Supporting both 2280 and 22110 drive lengths, this card offers flexible storage options and can be configured in RAID 0 for increased speed or RAID 1 for data protection.

With integrated thermal management including a real-time temperature sensor and an aluminum heat sink paired with a smart fan, the card maintains consistent performance during demanding tasks like 4K video editing or virtual machine hosting. Its versatile bracket options ensure compatibility with compact NAS enclosures and standard desktop towers, making it a practical upgrade for boosting storage speed without replacing existing arrays.

Key features

• Supports two M.2 SATA SSDs in 2280 or 22110 sizes for flexible storage expansion
• Enables RAID 0 for enhanced throughput or RAID 1 for data redundancy to suit different performance needs
• Works seamlessly with QNAP’s Qtier technology to automatically move frequently accessed files to SSDs for faster access
• Real-time SSD temperature monitoring helps prevent overheating and maintain reliability during intensive workloads
• Aluminum heat sink combined with a smart fan provides efficient cooling that adjusts based on system demand, reducing noise when idle
• Includes multiple bracket options (pre-installed low profile, flat low profile, and full height) for easy installation in various system types
• Ideal for accelerating storage performance in NAS setups, workstations, and environments requiring fast cache or tiered storage

Connectivity and compatibility

This expansion card connects via a PCIe Gen2 x2 slot, making it compatible with a range of QNAP NAS models as well as Windows and Linux workstations that have available PCIe slots. It supports SATA M.2 SSDs, which are widely available and cost-effective for adding fast storage layers. The included bracket options ensure it fits both compact NAS enclosures and standard desktop towers, providing flexibility for different system builds.

Performance and reliability

By connecting SSDs directly to the PCIe bus, the card significantly reduces latency and increases data throughput compared to traditional SATA connections. The RAID options allow users to tailor performance or data protection according to their needs. The thermal management system, including a temperature sensor and adaptive cooling fan, helps maintain stable operation during heavy workloads, protecting the drives and extending their lifespan.

Ideal uses and environments

The QM2-2S-220A is well suited for users who need to boost storage speed without overhauling their entire system. It fits well in home or small office NAS setups, professional workstations handling 4K video editing, virtual machines, or large data analytics. IT teams and system builders can quickly add a high-speed flash layer to existing storage arrays, improving responsiveness and efficiency in data-intensive tasks.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
