PCIe solid state storage

PCIe SSS is one of the four form factors for solid-state drives (SSDs).

PCIe, which stands for Peripheral Component Interconnect Express, is a high-speed expansion card format that connects a computer with its attached peripherals. PCIe has a point-to-point architecture. This means that each device connects to the host with its own serial link and does not have to share a bus.

In general, PCIe-based solid-state storage has better performance than server-based SATA, SAS or Fibre Channel (FC) solid-state drives because of the direct connections. This makes it a good choice for applications that have intensive input/output (I/O) requirements, such as , online transaction processing and data warehousing.
