Re: [Avid-L2] Hijack, more USB3 stuff

How do the perform when copying from the Toshiba pocket drive to an internal drive? The drive I found online

http://www.amazon.com/Toshiba-Canvio-Portable-Hard-Drive/dp/B005J7YA3W

has only an 8MB buffer, which is not very good for high rate data reads in my experience.

From memory, cheap Toshiba bus powered 1 TB pocket drives. (Bought last week)

They perform outstanding, just not from one to another.
Thought it might be bus related, but from SSD over USB3 to these things, it's fast....

can you post a link to the pocket drives you are using so we can see the specs of the drives?

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.
