Small size, easy to plug and unplug, multiple PCI-E interfaces on the motherboard can test multiple SSDs at the same time.This converter card uses differential line pair routing and supports PCI-E 3.0 4X signals.Supports M.2 of NVME protocols such for PM961, 960EVO, SM961, PM951, sm951, 600P, and T10. M.2 of the SATA protocol is not supported.M.2 hard drives with standard PCI-E or NVME on the SSD can be used.Support Solid State Disk Size: 2230, 2242,2260, 2280Performance: Solving the reading and writing of NVMe M.2 interface SSDInput interface: M-Key M.2 (Not Support SATA protocol M.2 NGFF)Output Interface: PCI-e X16Support Slot: PCI-e X4/X8/X16 (Not Support X1)NVMe SSD installation conditions:1.PCI-E X4/X8/X16 are available;2. install for Win10 system, for Win7 needs to install the driver, and the speed does not go up.3.The motherboard that does not support the NVME protocol cannot be used as a system disk and can only be used as a storage disk.About the motherboard:1.for motherboard chipset:B250/B150/H170/Z170, as long as the motherboard with M.2 interface generally supports NVMe.Support part of the Z97, specifically query the website or BIOS the Nvme option.B85/Z87 needs to update BIOS and be supported, most B85 does not M.2 Interface, you can use this adapter card.2.for AMD motherboard chipset:Support for the B350/X370/X399/A320 must be supported by Ryzen's CPU motherboard.Warm Tip:M.2 NGFF to PCI-E X16 converter card. Use this converter card to transmit the normal PCI-E X4 X8 X16 interface to M.2 NGFF interface.
