Specification Brand : GELRHONR BulletPoint1 : ✪ The M.2 NVME to PCIe3.0/4.0 adapter only fit for PCIe M.2 NVME based M Key.Do not support B&M Key.Support PCI-e 4x 8x 16x interface.Ideal for 1U. BulletPoint2 : ✪Help your computer work faster: M.2 NVME SSD to PCIe 3.0/4.0 adapter card for your computer,providing extremely fast read/write speeds, high-speed file access and transfers, and rapid boot times. BulletPoint3 : ✪ High Transmission Speed:Up to 32Gbps.The transfer mode is PCIe4.0x4 full speed.The SSD transmission speed of pci-e protocol is faster than that of SATA protocol and HDD.The LED will light up when the SSD is connected, and the read/write LED of the SSD can flash. BulletPoint4 : ✪The PCIe to M.2 NVMe adapter supports Windows/M-a-c/Linux OS.No driver required.Support M.2 NVME protocol SSD.Compatible 2280/2260/2242/2230mm size M.2 NVME SSD! BulletPoint5 : ✪Pay attention:Before you buy this adapter, you have to find out whether your mainboard is NVME-capable at all. Most old mainboards should have received BIOS updates in early 2015 that add NVME functionality. But you have to check that on the manufacturer's website!

Supports 2280/2260/2242/2230mm size NVMe M.2 SSDs.NOT supports any SATA based M.2 SSD.NOTE: It will not fit the PCIe x1 slot. Compatible with Windows, M*ac & Linux OS and no driver required. With advanced heat dissipation solution, double-sided copper hole porous heat dissipation structure reduces high heat generated. There are 4 fixing holes on the board, which are 22 * 32 mm, 22 * 42 mm, 22 * 60 mm and 22 * 80 mm. Note: The adapter only work for M-key socket, cannot work for B-key or B/M-key socket. PCI-e 4.0 down compatible with PCI-e 3.0 Indicator status: it is always on when it is powered on, and flashes when reading and writing. Package Contents: 1 * M.2 M KEY NVME to PCIE4.0 Adapter Card 1*Screwdriver 2*Screws Pay attention: 1.You have to find out whether your mainboard is NVME-capable at all. Most old mainboards should have received BIOS updates in early 2015 that add NVME functionality. But you have to check that on the manufacturer's website! 2.If your slot is PCIe 2.0 16x, the data transfer rate is limited to 2,000 MB/sec gross.So you have to be aware that your PCIe 4.0 16x slot is available ,then you will not achieve the full transmission rate. Generally maximum possible speeds for M.2 NVME SSDs: PCIe 1.0: 1GB/sec PCIe 2.0: 2GB/sec PCIe 3.0: 4GB/sec PCIe 4.0: 8GB/sec PCIe 5.0: 16GB/sec PCIe 6.0: 32GB/sec 3.Initialization on older boards: Once the NVME PCIe adapter is plugged into the board, nothing happens! The SSD is neither recognized as a boot device nor does it appear under the PCI devices under Linux, for example. But don't worry, neither the SSD nor the adapter are defective, because the SSD is only recognized under Windows as soon as you open the disk management. 4.The UEFI BIOS of older mainboards probably only recognizes an NVME SSD if it has already been GPT partitioned.
