All,
I happened to run a USB3 throughput test recently and it wrote 5 TB in 7 hours. I used a USB3 hub to let me hook up 5 1 TB drives and wrote to them simultaneously.
That's about 200 MB / sec.
It's the first time I've ever apparently saturated USB3. Does anyone know if 200MB / sec is a good max USB3 throughput?
fyi: Per the spec, it should be possible to hit 500MB/sec., but real world seldom hits the spec limits so 200MB/sec may be as good as it gets. If not, I may need to look for a better USB3 hub. (I do a lot of high bandwidth transfers in my job.)
Max rate is basically how fast the serial lines can push/receive data between the wire and the host or device. You might be able to sustain maximum speeds when using something like a static memory device, but probably not even for flash memory (in either a stick of SSD device) because flashing new data is comparatively slow. And spinning platters with read/write heads on seeker arms have no chance of keeping up that kind of speed.
