Video Streaming:
* Video stream rates are dependent on several factors beyond the AccuStream board.
* The AccuStream boards can run in PCI 32 & 64 bit slots.
* The AccuStream Express boards can run in PCIe x4, x8 and x16 slots.
* For fastest stream rates and data transfers,  PCIe is recommended.
* System processor, memory & disk speed all contribute to transfer rate speeds.
* Below are transfer rates to memory on "typical" PCI 32 & PCI 64 bit machines that perform at 125 MB/second transfers,
   and 250 MB/second transfers respectively, as well as performance on “typical” PCIe x4 systems (500-700MB/s). 
   Your performance may vary on slower machines.

 * For fastest video streaming, use computers with a  PCIe x4 bus or higher, 
   1GB of more memory and a SATA Raid striped disk or SSD sub-system is recommended for best
    performance when streaming to disk.   Or for best performance, use the real-time hardware compression
of the AccuStream Express HD+C boards for high quality streaming video at bit rates from 2-30 Mbps, taking
up very little disk space and bus bandwidth.
