??? I am confused.
According to your test, it took 25 seconds to read 1,024,000 bytes or,
one megabyte. If you devide 1024000 by 25 the result is 40960 closer to
40kbytes/sec or 327Kbits. Pleas show me your math to get 12k/sec 12k
what? bits bytes blocks.
I am sure I am missing something here. Just not sure what.
Your test is exactly what I did and got 30secs for a megaread pass. to
me that seems to be 34kbytes/sec.
It must be that I am confused just how much data megaread is reading!
is it reading megabytes, or megabits?
Whatever it is reading, its a bunch faster than floppys! ha ha ha
