PCIe X4 Adapter Card For NVME SATA M.2 NGFF SSD Dual Purpose Hard Drive Features: Adapter card size:126*68MM Points to note This adapter only supports M.2 NGFF SATA protocol SSD hard disk 2280 2260 2242 2230 size And M.2 NVME PCIE x2 x4 22110 2280 2260 2242 2230 size SSD hard disk to be used on the computer motherboard slot PCIe x4 interface Note SATA protocol M.2 NGFF SSDs to SATA interface This SATA interface needs to be connected to the SATA interface of the motherboard with a SATA cable in order to be used This adapter is PCIEx4 interface,can be inserted into the computer PCIe x16 x8 and PCIex4 slots But the speed is still running PCIe x4 speed This product is compatible with PCIe 4.0 3.0 2.0 1.0, but the interface bandwidth is different speed Whether it can be used as a system disk is related to your motherboard,not related to the adapter card General use of DDR4 memory motherboards can support NVME protocol hard disk as a boot disk This product is inserted into the motherboard's PCIEx4 3.0 4.0 or PCIEX8 3.0 4.0 Or PCIEX16 3.0 4.0 slot,which is the motherboard's graphics card slot Don't insert the PCI slot by mistake Inserting the wrong one may burn the motherboard,the adapter and your SSD Note: SSDs cannot run at full speed with this adapter,try to plug it into the PCIE 3.0 4.0 slot on your motherboard If plugged into a PCIE 2.0 or PCIE 1.0 slot, the speed is very slow If your motherboard chipset is below 9 series,using NVMe hard disk is not supported as system boot disk It is only supported as a data storage disk,unless you will change and re-flash your motherboard BIOS It is not the case that if your motherboard has a PCIE interface,you can use a PCIE interface SSD The key is to see if your motherboard BIOS can support PCIE interface SSDs 9 Series of chipsets below normal circumstances is certainly not support PCIE interface solid state disk startup Please insert the adapter into your motherboard's PCIe connector correctly, not into the PCI connector Wrong insertion may burn the adapter and the motherboard Installation of the system must use the original installation disk of Win 10 Package includes: 1*PCIe x4 Adapter card Note: Only include the above package products,Battery not included Specifications are manually tested and are for reference only Please allow 0-1cm error due to manual measurement Please make sure you don't mind before bidding Due to the difference between different monitors Pictures may not reflect the actual color of the item.Thank
