CompactPCI® Serial • Quad M.2 PCIe x4 (NVMe) SSD Module Carrier Board

The SE4-TEMPO is a peripheral slot card for CompactPCI® Serial systems, equipped with four M.2 sockets for SSD (Solid-State Drive) modules.

Each M.2 socket can accommodate an NVMe type SSD module, with a PCI Express® x4 Gen3 interface for superior data transfer rates. When used as main mass storage devices in a system, the NVMe SSDs can speed up the overall system performance dramatically.

The SE4-TEMPO is suitable for NGFF SSD module sizes up to the 2280 form factor. The M.2 sockets are mechanically coded with an M-Key for popular PCIe x4 (NVMe) modules.

For optimum SE4-TEMPO performance, a PCI Express® Gen3 x8 enabled backplane slot is recommended (CompactPCI® Serial fat pipe slot).
