PCI - Peripheral Component Interconnect / PCI Express (PCI-e)

           
        PCI-SIG - PCI Express - PCI-X 2.0

  • PCI Express bidirectional, and faster then the older PCI and AGP interfaces
  • guarantees each device dedicated bandwidth through the system controller
  • slots are defined by their bandwidth, or number of data lanes - 1, 4, 8, 16 lanes
  • one card can support 1 to 32 lanes at 250 MB/sec each, up to 8 GB/sec
  • PCI Express x1 about twice as fast as PCI
  • 4-lane slot can transfer data at up to 1 GBps 
  • PCI Express x8 is around the speed of the fastest AGP
        up to 2 GBps - almost 2X 133MHz PCI-X slot at max throughput just over 1 GBps
  • previous PCI Extended, PCI-X

SATA -- Serial ATA / eSATA -- External SATA

       

  • Designed to replace the older ATA and SCSI formats, offering higher performance with ease of connection
  • ATA drives low cost, high capacity
  • Internal data rates reaching up to 75 MB/sec, USB and 1394 interface rates are bottleneck
  • Internal: SATA 1.5 Gb/sec (150 MB/sec) or SATA 3 Gb/sec (300 MB/sec)
  • External: eSATA with more robust cables and connections (multiple insertion , shielded)
        Electrical Static Discharge (ESD) , Electro Magnetic Interference
