Ooops,
sorry, I forgot that I´m NOT using the Win-defrag, I´m using the "TuneUpUtilities 2013" defrag

.
What makes sense ?
USB 2.0 or now 3.0 would as well be state of the art. SSD-HD too. CPU of more than 80 MHz also.
Even Yamahas Tyros4 is using USB 2.0. No ! The say it´s USB 2.0.
But speed is as slow as USB 1.1 !
And it´s using an internal USB-to-S-ATA converter that makes the HD too slow for recording whilst using SA2-Voices.
