Feature:1.Adapter card support socket 3 (GEN 3 PCIe X4 or NVME) M key M.2 NGFF SSD and socket 2 (GEN 2 PCIe X2) B+M key M.2 NGFF SSD SSD to PCIe X4 slot.2.The speed and other properties is not changed，only form conversion interface.3.Support size: 22*42 mm，22*60 mm，22*80 mm M.2 NGFF SSD.4.You can connect it to desktop5.It's compatible with Windows 7，8，8.1，10，MAC OS 10.9，MAC OS 10.10 or higher version operating system and does not require any software drivers，because adapter card does not need through the integrated circuit to complete this function.About M.2 NGFF SSD interface standard:1.Socket 2(B+M key):there are SATA mode (such as THNSNH128G8NT/ THNSNH128GDNT/MZNTD256HAGM etc models of SSD) and PCIe X2 mode (such as PX-AG128M6E PX-AG256M6E PX-AG512M6E SD6PP4M-128G SD6PP4M-256G HFS256GA6MND HFS512GA6MND HFS128GB9MND HFS256GB9MND HFS512GB9MND LGT-256B1P LGT-512B1P PT42 APP064G3FA-ATM THNSNN128GSX7 THNSNN256GSX7 THNSNN128GVX7 THNSNN256GVX7 etc models of SSD)，it there are two gaps at the hard disk interface part.2.Socket 3 (GEN3 M key):PCIe X4 mode，such as XP941 (MZHPU128HCGM MZHPU512HCGL MZHPU256HCGL)，SM951 PCIE-AHCI (MZHPV128HDGM MZHPV256HDGL MZHPV512HDGL)，SM951 PCIE-NVME ( MZVPV128HDGM MZVPV256HDGL MZVPV512HDGL) ，PM951 PCIE-NVME ( MZFLV128HCGR MZFLV256HCHP MZFLV512HCJH MZVLV1Y0HCJH)，PM961 (MZFLW1T0HMLH).950 PRO (MZVKV256 MZVKV512) SH2280S3 SHPM2280P2 THNSN5128GPU7 THNSN5128GPU7 THNSN5256GPU7 THNSN5512GPU7 THNSN51T02DU7 etc models of SSD.it there are one gap at the hard disk interface part.Notice:1: M.2 NGFF (PCIe x4 or PCIe x2) SSD do the system boot disk need the computer motherboard to support，not all motherboards support start function， please consult your motherboard vendor supporting details.2: Only sells adapter card， not including hard disk and data cables.3: The computre must have a PCIe 3.0 x16 slot or PCIe 2.0 x16 or PCIe 2.0 x4 slot or PCIe 2.0 x8 slot or higher.we suggst insert the adapter card in PCIe 3.0 x16 slot of your motherboard，because this can get the highest reading and writing speed of the hard disk.Other slots can not be inserted into any device if the adapter card insert into PCIe 2.0 slot，because the PCIe 2.0 slot is Shared，if multiple PCIe 2.0 slots together inserted the device，computers will not be able to identify solid state drives or reduce the running speed of solid state disk.4：We provide the related test data are for reference only，not as a standard of acceptance;you machine configuration and BIOS version and SSD to determine the speed.5: Please enter the disk manager to hard disk partition and format the hard disk If you open "my computer" can't see the increase of disk partitions.6: Your computer motherboard and hard disk itself to determine the running speed， adapter card for speed without any loss，because adapter card does not need through the integrated circuit to complete this function.7: This product performance is being improved unceasingly， like has the change， not separate informs even slightly.Pictures for reference only， subject to our available products.Package Content: 1x Interface
