QNAP QM2-4P-384

Overview

The QNAP QM2-4P-384 is an internal expansion card designed to add up to four M.2 2280 NVMe SSDs to a compatible QNAP NAS system. It connects via a PCIe Gen3 x8 interface, significantly increasing data throughput and reducing latency without occupying traditional 3.5-inch drive bays. This card integrates seamlessly with QTS features like SSD caching and auto-tiering, optimizing storage performance by keeping frequently accessed data on fast NVMe drives while offloading less active files to hard disks.

Key features

• Supports four M.2 2280 NVMe SSDs through a high-speed PCIe Gen3 x8 interface for enhanced data transfer rates.
• Works with QTS SSD caching and auto-tiering to accelerate access to critical data and improve overall system responsiveness.
• Built-in temperature sensors provide real-time monitoring of each drive’s thermal status via the QTS dashboard.
• Includes a cooling module combining a heatsink and smart fan to prevent thermal throttling during intensive tasks like backups or sustained writes.
• LED indicators on the bracket offer immediate visual feedback on drive activity and status, simplifying maintenance and troubleshooting.
• Compact design consolidates multiple SSDs into a single PCIe slot, saving space and avoiding the need for external enclosures.

Connectivity and compatibility

This expansion card connects directly to a PCIe Gen3 x8 slot on compatible QNAP NAS devices, enabling high-speed communication with the system. It supports M.2 2280 NVMe SSDs, which are widely available and offer fast storage options. By integrating with QTS software, it enhances existing NAS capabilities such as SSD caching and auto-tiering, making it a versatile upgrade for users looking to boost storage performance without replacing their entire setup.

Performance and reliability

The QM2-4P-384 is engineered to maintain stable performance even under heavy workloads. Its cooling module actively manages heat, preventing performance drops caused by thermal throttling during long data transfers or backups. Real-time temperature monitoring ensures that users can keep an eye on drive health, reducing the risk of unexpected failures. This makes the card a dependable choice for demanding applications like virtualization, database management, and 4K video editing.

Ideal uses and environments

This expansion card suits IT administrators who require higher IOPS for virtual machines, content creators needing fast scratch disks for video projects, and home lab enthusiasts seeking rapid data access. It fits well in environments where maximizing storage speed and efficiency is critical, while preserving existing hard drive capacity for bulk storage. The card’s compact design and integration with QTS features make it a practical upgrade for enhancing NAS performance without adding external hardware.

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.
