So it appears that the USB 3.0 specification is “up to” XYZ mb/s, but in reality it is lower.
However the lower number still seems to be adequate for video throughput which is 35mb/s per stream for XDCAM for example, so 4 streams stacked would require roughly 140mb/sec which is well within the minimum reality throughput.
The speed of an individual drive vs a RAID 0, for example, would be improved also.
So which is higher, the USB data throughput, or the read/write ability of a 7200rpm drive?
