At 137,900 bytes per second.
This is the speed at which Facc peaks (as measured by DiskPerf). As Facc
uses the standard file system handler and the RAM: device which uses its
own handler (and reaches speeds of 800,000 bytes per second using the same
test) we can infer that the standard file system's maximum through put is
the limiting factor.
Truely high performance will be acheived through the use of alternate file
system handlers or through the use of co-processors implementing greater
and greater sections of the disk subsystem directly on card.
As for the ASDG SDP, you can expect a stage 1 SDP to be very near the
137,900 bytes per second. Stage 2 will be higher. Stage 3, higher still.
These stages represent succesive generations of SDP software (same
hardware).
Does this help to answer your question?
