Given the limited number of M.2 slots on motherboards for desktop PCs, workstations, and NAS devices, expanding with multiple NVMe SSDs requires motherboard support for lane splitting, which involves a cumbersome setup process. older platforms lack native support for multiple NVMe storage devices, and stacking multiple drives can lead to poor thermal performance. The LeKuo PX24M41 PCIe x16 to 4 xM.2 NVMe adapter card, equipped with the high-performance IX8024 PCIe switch chip and featuring a PCIe Switch architecture design, eliminates the need for motherboard lane splitting support; allowing a single physical PCIe x16 slot to expand to four NVMe SSDs. It supports independent identification and concurrent access to multiple drives. Featuring an all-metal cooling structure and a built-in fan, it is suitable for a variety of scenarios, including video editing, high-performance computing, and multi-drive storage acceleration.
Most traditional multi-M.2 expansion solutions rely on the motherboard’s lane splitting feature, which places high demands on the motherboard chipset and BIOS settings; some older motherboards do not support this at all. Simple adapter cards without a switch chip are prone to issues such as bandwidth conflicts and mutual interference between drive slots, resulting in insufficient stability for concurrent operation of multiple drives.
The LeKuo PX24M41 employs a hardware-level PCIe switch architecture, utilizing the IX8024 chip to handle lane allocation and data scheduling, enabling stable multi-drive expansion at the hardware level: PCIe 4.0 upstream lanes
The upstream interface utilizes PCIe 4.0 x8 bandwidth, with a single-channel data rate of 16 GT/s, providing ample transfer support for up to four NVMe SSDs; the product must be installed in a physical PCIe x16 slot on the motherboard and is compatible with PCIe 4.0 and 3.0 motherboards, making it suitable for both new and older platforms.
Hardware-Level Independent Channel Allocation
A dedicated switching chip assigns an independent transmission channel to each SSD, allowing all four SSDs to be recognized by the system and operate concurrently. There is no need to enable channel splitting in the motherboard BIOS, which significantly lowers the deployment barrier and allows even ordinary users to get started quickly.
Key Technology Breakdown: Stable Operation with Four-Drive Expansion; Adaptability to Multiple Scenarios
1. Concurrent NVMe operation across four drives delivers stable performance
- A single card supports the simultaneous connection of up to four M.2 NVMe solid-state drives, with all SSDs sharing the upstream total bandwidth; this provides higher available bandwidth when a single drive is in use and maintains relatively stable transfer performance when multiple drives are operating simultaneously.
- Complies with the PCI Express M.2 Specification versions 1.0 and 1.1, and is compatible with NVMe solid-state drives that meet the PCIe 4.0 and PCIe 3.0 specifications.
- Supports M.2 SSDs in four common form factors: 2230, 2242, 2260, and 2280; storage devices of different specifications can all be installed and used.
2. No-Channel-Splitting Design for Easier Deployment
- No need for the motherboard to support PCIe channel splitting; simply insert the card into the corresponding PCIe slot for automatic detection and use. With minimal BIOS configuration steps, it is more user-friendly for general users and non-professional IT staff.
- Supports software RAID expansion, allowing users to configure RAID modes through the operating system to meet various needs such as data security, capacity consolidation, and performance scaling.
3. Active cooling design for more reliable long-term operation
- Features an all-metal heat sink enclosure that provides physical protection against wear and pressure while also helping to dissipate heat generated during hard drive operation.
- Includes a built-in cooling fan that creates an active cooling airflow path, alleviating heat buildup when multiple NVMe SSDs are operating under heavy loads and helping to ensure stable, long-term device operation.
4. Compatible with Multiple Operating Systems and Platforms
- Supports Windows.
- Supports Linux systems and is compatible with Linux environments such as servers, software routers, and NAS devices.
- Supports macOS; Apple workstations can also use this product to expand NVMe storage capacity.
Real-World Scenarios: Solutions for High-Speed Storage Expansion Across Multiple Domains
1. Expanding NAS Storage with Multiple Drives
Home or small-office NAS devices have a limited number of native M.2 slots, which restricts the expansion of cache drives and storage drives, thereby affecting the system’s overall read/write performance and maximum capacity.
Solution Benefits: A single PCIe slot can support up to four NVMe SSDs, which can be used as a cache layer or an all-flash storage pool to enhance the NAS’s random read/write capabilities and performance during concurrent access by multiple devices.
Actual Performance: When multiple users simultaneously access shared files or perform real-time data backups, the system responds more quickly, and storage performance fluctuates less under heavy loads.
2. High-Speed Storage Server for Small Studios
Content creation studios require high-capacity, high-speed storage to handle 4K/8K footage and project files; the read/write speeds of traditional SATA hard drives struggle to meet the demands of real-time access to multi-track footage.
Solution Benefits: A high-speed storage pool comprising four NVMe drives delivers significantly faster media read and write speeds compared to SATA SSDs, supporting workflows such as multi-camera editing and 3D rendering.
Actual Performance: Loading times for large project files are reduced, real-time previews of multi-track media are smoother, and rendering and export efficiency are improved.
3. Local AI Inference and Deep Learning Computation
Local AI training and inference scenarios demand high storage read speeds; a single NVMe SSD can easily become a performance bottleneck during dataset loading.
Solution Benefits: Concurrent read operations across multiple NVMe drives accelerate dataset loading and, when combined with GPU computing, reduce data wait times.
Practical Applications: Suitable for local deep learning model training, AI inference, and similar scenarios, ensuring more reliable storage performance.
4. NVMe Expansion and Upgrade for Older Motherboards
Older desktop and server motherboards have few native M.2 slots or may not even support the NVMe protocol, making it impossible to use high-speed SSDs directly.
Solution Benefits: Multiple NVMe SSDs can be expanded via PCIe slots without replacing the motherboard, enabling a storage performance upgrade at a lower cost.
Actual Performance: Even older platforms can benefit from the high-speed read/write capabilities of NVMe SSDs, improving the system’s overall storage response time and helping to extend the device’s lifespan.
5. Professional Content Creation Workstations
In tasks such as video editing, 3D rendering, and audio production, project files are large and place high demands on both storage read/write speeds and capacity.
Solution Benefits: A single card expands to four high-speed SSDs, simultaneously boosting both capacity and speed, allowing for the storage of source material, project caching, and final output to be handled entirely on high-speed storage media.
Actual Performance: Faster read/write speeds for copying large source files and project caching, resulting in reduced wait times during the creative process.
