The SE1-PITCH is a peripheral slot card for CompactPCI® Serial systems, equipped with two M.2 sockets for SSD (Solid-State Drive) modules. One of the M.2 sockets is suitable for a NVMe type SSD module, with a PCIe x4 Gen3 interface for superior data transfer rates. When used as main mass storage device in a system, the NVMe SSD can speed up the overall system performance dramatically. The other M.2 connector can accommodate a classic AHCI SATA style SSD, used e.g. as backup for the NVMe module.
The SE1-PITCH is suitable for all module sizes defined by the M.2 specification for SSD drives, up to the 22110 form factor. In order to avoid mix-up, both M.2 sockets are mechanically coded. The NVMe module socket is provided with an M-key, and the SATA module connector features a B-key, according to the PCI Express® M.2 Specification (PCI-SIG). For optimum NVMe SSD module performance, a PCI Express® x4 enabled backplane slot would be required (e.g. CompactPCI® Express fat pipe slot). In addition, SATA backplane support is needed for the SATA SSD module.
