Features: 1.B-Key interface can insert with SSD of M.2 NGFF SATA protocol, the insert SATA line to connect mainboard. 2.M-Key interface can insert with SSD of M.2 NVME PCI-E protocol. PCI-E transmission data is able to connect mainboard without accessing SATA line. 3.12V+3.3V double voltage, more stable than single voltage, effective SSD temperature decrease, less heat, faster speed, with more LED status indicator. 4.SSD contact surface is super thick gold plating, its heat dissipation enhanced after adding heat conducting medium. 5.High speed and large capacity storage interface for high-speed SATA3/6Gbps is determined. The speed is decided by the host end of the computer motherboard, and the adapter card does not affect the performance of NGFF SSD. specification: B-Key interface can insert with SSD of M.2 NGFF SATA protocol, the insert SATA line to connect mainboard. M-Key interface can insert with SSD of M.2 NVME PCI-E protocol. PCI-E transmission data is able to connect mainboard without accessing SATA line. 12V+3.3V double voltage, more stable than single voltage, effective SSD temperature decrease, less heat, faster speed, with more LED status indicator. SSD contact surface is super thick gold plating, its heat dissipation enhanced after adding heat conducting medium. High speed and large capacity storage interface for high-speed SATA3/6Gbps is determined. The speed is decided by the host end of the computer motherboard, and the adapter card does not affect the performance of NGFF SSD. Power supply mode: PCI-E power supply, support system startup function. Provides 2 * M.2 slots, M NGFF interface, B NGFF interface. Users are allowed to utilize standard SATA-IO M.2 SATA SSD to switch to desktop computer to become SATA hard disk. Can connect and use M.2 (NGFF) SSD as a laptop hard disk card 11.M.2 (NGFF) SSD, through whose NGFF slot transmission to connect the host for data transmission. PCI-E to NGFF adapter is a new solid-state interface card with M.2 new interface. : Material: PCB Color: Shown as picture Support M.2 Card Size: 22*30mm, 22*42mm, 22*60mm, 22*80, 20*110 Port: PCI-E 1X, PCI-E 4X Support System: Compatible for WIN7/WIN8/WIN8.1/WIN10 system Package Weight: Approx.123.5g/4.4oz Package List: 1 * Adapter Card 1 * Back Plate 1 * SATA Cable 1 * Screw Pack Note: 1.
