Universal Compatibility - Works with ANY Motherboard

The Lekuo PX24M41 PCIe 4.0 x16 to 4x M.2 NVMe Adapter eliminates the need for motherboard bifurcation support. Featuring an integrated PCIe Switch chipset, this expansion card provides four fully independent M.2 NVMe slots that are automatically recognized by the operating system - no BIOS configuration required.

High-Performance PCIe 4.0 Connectivity

Utilizes PCIe 4.0 x8 electrical interface (requires x16 physical slot) to deliver up to 16 GB/s aggregate bandwidth across four M.2 NVMe SSDs. Each SSD operates independently with concurrent read/write access, making it ideal for high-throughput applications such as video editing, large database operations, and virtualization workloads.

Flexible M.2 Form Factor Support

Accommodates M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 lengths. Adjustable mounting positions with included screws and thermal pads ensure secure installation and optimal heat dissipation for drives of any length.

Advanced Thermal Management

Equipped with a precision-machined aluminum heatsink and four self-adhesive thermal pads to effectively dissipate heat generated during sustained high-speed data transfers. Maintains stable performance even under continuous heavy loads.

Plug-and-Play Installation

Fully compatible with Windows 10/11, Linux (Kernel 4.6.4+), and macOS. No drivers required - simply insert the card into an available PCIe x16 slot, mount your M.2 SSDs, and start using them immediately.

Q: Does the Lekuo PX24M41 require motherboard bifurcation support?
A: No. The Lekuo PX24M41 features an integrated PCIe Switch chipset that automatically handles bandwidth distribution. It works with ANY motherboard that has a PCIe x16 slot - no BIOS bifurcation configuration required. ---

Q: What is the difference between PCIe x16 physical and x8 electrical?
A: The card uses a PCIe x16 physical connector (the long slot) but only utilizes 8 lanes electrically (x8). This provides up to 16 GB/s total bandwidth, which is dynamically shared among all four M.2 SSDs. Most PCIe x16 slots support x8 electrical devices.

Q: Can I use SATA M.2 drives with this adapter?
A: No. This adapter only supports NVMe protocol M.2 SSDs (M-Key). SATA M.2 drives (B-Key or B+M-Key) are NOT compatible. Check your SSD specifications before purchasing.

Q: Do I need to install drivers?
A: No drivers required for Windows 10/11, Linux (Kernel 4.6.4+), or macOS. The adapter is fully plug-and-play - simply insert the card, mount your SSDs, and they will be automatically recognized by the operating system. ------

Q: Can I boot from an M.2 SSD installed on this adapter?
A: Yes, in most cases. Boot support depends on your motherboard's UEFI/BIOS. Most modern motherboards (2015+) support booting from PCIe-based NVMe drives. Check your motherboard manual or BIOS settings for NVMe Boot or PCIe Storage Boot options.

Q: How is the 16 GB/s bandwidth shared among four SSDs?
A: The bandwidth is dynamically allocated based on real-time usage. If one SSD is performing heavy read/write operations, it can utilize more bandwidth. If all four SSDs are active simultaneously, the bandwidth is distributed proportionally. Total throughput depends on workload and SSD performance.

Q: What M.2 form factors are supported?
A: The adapter supports M.2 NVMe SSDs in 2230, 2242, 2260, and 2280 lengths. Adjustable mounting positions with included screws and thermal pads accommodate all standard sizes.

Q: Does the heatsink provide adequate cooling?
A: Yes. The aluminum heatsink combined with four self-adhesive thermal pads effectively dissipates heat during sustained high-speed transfers. For extreme workloads (24/7 operation at maximum throughput), consider adding case fans for additional airflow.

Q: Can I use the Lekuo PX24M41 for software RAID?
A: Yes. The Lekuo PX24M41 is ideal for software RAID configurations (RAID 0/1/5/10) using Windows Storage Spaces, Linux mdadm, or macOS Disk Utility. Note: Hardware RAID is NOT supported - this is a passive PCIe switch adapter without RAID controller functionality.

Q: Is the Lekuo PX24M41 compatible with PCIe 3.0 motherboards?
A: Yes. The Lekuo PX24M41 is backward compatible with PCIe 3.0 and 2.0 motherboards. On a PCIe 3.0 x8 slot, total bandwidth is approximately 8 GB/s (half of PCIe 4.0). For maximum performance, install the card in a PCIe 4.0 x16 slot.
