Bude to fungovat v PCIe x16, který má už ale pouze 4 linky???

The AXAGON PCEM2-ND PCI-Express controller allows you to connect two NVMe M.2 SSDs to a desktop computer and create a RAID array. Its high-quality workmanship, compact size, and thoughtful design make the adapter an ideal choice for upgrading a desktop computer that doesn't have an M.2 slot. It is also useful if you're short on M.2 slots. The adapter is universal and compatible with any motherboard, and will even work on motherboards without PCI-Express bifurcation support. This unique functionality is powered by a high-quality chip from Asmedia. Thanks to the PCI-Express 3.0 interface, compatible with x8 and x16 slots, you can achieve maximum transfer speeds of up to 4000MB/s (4GB/s). The controller supports both single-sided and double-sided NVMe (PCI-Express) M.2 SSDs. The adapter has no SSD capacity limitations and can be used with M.2 drives up to 22×110mm in size.
When fitted with drives shorter than 22110, the rear part of the card can be detached to fit into a small space. A low-profile bracket is included for mounting the adapter in low-profile cases. The M.2 controller card also has an integrated PCI-Express slot lock for a more secure fit in the PCIe slot. The lock can be easily broken off if necessary. The PCIe adapter supports SW RAID, which can be created using suitable software or the integrated tools in your operating system. By setting up RAID 1, you achieve effective data protection through mirroring. The chip is cooled by a high-performance passive heatsink. For cooling M.2 drives, you can use heatsinks up to 22mm wide; the AXAGON M.2 CLR-M2L3, CLR-M2L6 and CLR-M2L10 heatsinks are suitable. An LED indicator signals connection or data transfer in the M.2 slot. Installation is completely automatic and can be done by anyone.
