tech: PCI Express (PCIe) SSD

What is PCIe solid state storage? - Definition from WhatIs.com
"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."


"The higher performance of PCIe SSD (Fusion-io'sioXtreme Pro can deliver a throughput of 2.1 Gbps)"

"PCIe flash storage technology, an upgrade that promises to boost performance by 10 times over the hard drives in current models."

OCZ PCI Express (PCIe) SSD:

bootable SSDs take the SATA bottleneck out of the equation and use a high-speed PCI Express architecture coupled with a sophisticated workstation-grade RAID array that virtualizes the SSD controllers ensuring easy installation and seamless functionality.
