PCIe 3.0 NVMe M-Key M.2 to U.2 Adapter Card, SFF-8639 Full Aluminum U.2 Hard Drive Enclosure for 2.5" SSD

Note: This adapter card has a 2.5-inch NVMe PCIe interface, not the ordinary 2.5-inch SATA interface! The 15-pin position of the 2.5-inch SATA interface on the adapter card is the power interface, while the SATA interface is vacant. Don't come to me and tell me that the SATA interface doesn't work at that time.

If you want to test this adapter card, your motherboard chipset must be of the 9 series or above, and you should be using Windows 8.1 or Windows 10 operating system. AMD chipset motherboards are not recommended for testing this card! Disks using the NVME protocol without a dedicated hard drive driver have poor compatibility with AS SSD testing software. It is recommended to use Crystal DiskMark software to test the speed!

Please all stop inquiring about the speed of the adapter card. This adapter card merely changes the shape of the interface, that is, it takes the signal lines from the original hard drive interface and converts them to another interface shape. Such a conversion does not require passing through an integrated circuit chip. Since it does not pass through an integrated circuit chip, it has no impact on the speed performance of your hard drive, nor does it require any drivers (the operating system loads the driver for your hard drive, the adapter card does not need a driver because there is no chip). The overall speed depends on how fast your hard drive is and how fast your computer can support (many computers can increase the speed significantly by upgrading the BIOS). This is to be stated.
