1、This product supports B‑Key+M‑Key M.2 sizes: 2230, 2242, 2260, 2280, 22110. 2、12V+3V dual voltage, more stable than single voltage, effectively reduce SSD temperature, heat generation is smaller and speed is faster. 3、Increase the LED status indicator, it is more convenient and practical to use. 4、The SSD contact surface is ultra‑thickly gold‑plated, which can efficiently dissipate heat after adding a heat‑conducting medium. 5、Support high-speed SATA3/6Gbps high-speed mass storage interface, support NGFF of SATA signal and PCI-E signal to work at the same time. 1 x Adapter Card(without hard disk)1 x Chassis Large Baffle1 x Chassis Small Baffle1 x SATA Cable1 x Screwdriver3 x Accessories  Item Type: Adapter Card Features: 1. Support B-Key+M-Key M.2 size: 2230, 2242, 2260, 2280, 22110; 2. The B-Key interface can be inserted into the M.2 NGFF SATA protocol SSD, and then insert the SATA cable to connect the motherboard to use PCI-E power supply, without external power supply; 3. The M-Key interface can be inserted into the M.2 NVME PCI-E protocol SSD, PCI-E transmission data does not need to be connected to the SATA cable to connect to the motherboard; 4.12V+ 3.3V dual voltage, dual voltage is more stable than single voltage, effectively reducing SSD temperature, less heat generation, faster speed, while adding LED status indicator, it is more convenient and practical to use; 5. The SSD contact surface is super-thickly gold-plated, which can efficiently dissipate heat after adding a thermal medium; 6. Power supply mode: PCI-E power supply, support system startup function; 7. Support high-speed SATA3/6Gbps high-speed large-capacity storage interface, the speed is determined according to the host side of the computer motherboard, and the adapter card does not affect the performance of NGFF SSD; 8. Provide 2 M.2 slots, M NGFF interface, B NGFF interface; 9. Allow users to use standard SATA-IO M.2 SATA SSD to transfer to a desktop computer to become a SATA hard disk; 10. It can be connected to use M.2 (NGFF) SSD as a laptop hard disk card 11.M.2 (NGFF) SSD is connected to the host for data transmission through the NGFF slot of this board card; 12.M.2 specification revision 0.9 Warm reminder: M.2 NVME PCI-E protocol SSD needs a driver to be used as a system disk for booting, and the system above Win 8.1 has its own driver.Reminder: M.2 NVME PCI-E protocol SSD needs a driver to be used as a system disk for booting, and for Windows 8.1 or higher systems have their own drivers.Regarding the NGFF usage of SATA signal and PCIE signal: 1. Connect the 7PIN SATA on the adapter card to the SATA interface of the desktop motherboard, and the signal is converted into a NGFF adapter card for SATA signals 2. The following interface uses the NGFF of the PCIE signal interface, which directly supports the M.2 SSD connected to the PCI-E 3. Can support NGFF of SATA signal and PCI-E signal to work at the same timepacking list:1 x Adapter Card1 x Chassis Large Baffle1 x Chassis Small Baffle1 x SATA Cable1 x Screwdriver3 x Accessories
