Internal Host interface: PCIe Output interface: M.2, SATA NVMe TRIM support Purpose: PC 8 Gbit/s Black, Gold The internal AXAGON PCEM2-D adapter allows to connect as many as two M.2 SSD to a desktop. So, it is an ideal choice for upgrading a desktop that has no M.2 slot. The adapter supports the use of both one-sided and double-sided SATA and NVMe (PCI-Express) M.2 SSDs. The reduction does not limit SSD capacity, and any M.2 cards with a length up to 110 mm can be used. The simultaneous operation of both disks is commonplace.Thanks to PCI-Express 3.0 4-lane interface compatible with x4, x8 and x16 slots, a speed as high as 8GBps can be achieved. When compared to standard SATA SSDs, bit rates of NVMe SSDs are many times higher.The high quality card design, including copper-plated vents, assists in a better dissipation of heat generated during the M.2 SSDs operation.Double blue LEDs indicate either power on or data transfer in the M.2 slot. The package also contains a low profile blankin
