Feature: 1. Supports high speed mass storage interface. The speed is determined by the host end of the computer motherboard. The adapter card does not affect the performance of ngff SSD 2. NVME M.2 to PCI‑E adapter card is a high speed SSD card with M.2 new specification interface, with high speed, high performance and extreme speed experience 3. Support the system startup function. The motherboard BIOS is required to support PCI-E startup 4. The contact surface of SSD is super thick gold plated, which can dissipate heat efficiently after adding heat conducting medium 5. Supports two M‑Key/B&M key NVME PCIe protocol SSDs, making it more durable Specification: Item Type: Transfer Card Model: PN02-RTK Material: Aluminum Alloy, PCB Speed: 2 x 32Gbps Interface: PCIe-X8 Compatibility: 2230 , 2240 , 2260 , 2280 , 22110 (Requires the Motherboard to Support the Splitting Function). Package List: 1 x Transfer Card 1 x Baffle 1 x Crewdriver4 x Screw 2 x Nut Note: SSDs that do not support the B key M.2 SATA protocol and SSDs that use the M.2 nvme PCIe protocol can only be used as system disks for startup and disk reading (when systems above win10 have their own drivers, win10 can realize soft RAID)
