[Avid-L2] Hijack, more USB3 stuff

On a job now on location where i have a lot of USB 3 drives.

Strange stuff happens:

I record to one USB3 drive, and a PIX recorder.

After the shoot, i want to copy my recordings from the PIX recorder to the USB 3 (pocket) drive.

No probs, connect the SSD PIX drive over USB 3, and get 100 MB/sec

Now, i want to copy the whole shebang of the pocket drive to another pocket drive.

Then i get just 32 MB / sec.

When copying from another source to a pocket drive it's fast. Tried all combo's, got 10 pocket drives, only pocket - pocket is slow, all other combo's are fast.

WTF?

(Ok, i can live with it, just leave the stuff on to do the copy overnight, but i was expecting to use lunch break to make a backup of the morning shoot. It's a lot, continuous recording of 5 channels...)

Tried all combo's of ports, that's not it.

Oh, i'm on a HP z420

I like the fact that both the devices are powered externally.
I find that self powered usb3 drives consistently unmount themselves, I never have the issue with powered usb3 storage. The USB3 card I use is not externally powered so I think I'll spend the 30-40 bucks to see if that fixes the unmounting issue. On the other topic my Esata drives do provide consistent stable throughput.
