Why Delkin Juggler, Why? My BMPCC 6k recording failure.

Continuing with the BMPCC 6k recording issue, decided to see if it might be a hardware issue and not a cable issue.
So it turns out I'm getting less then 20 mb read/write speed for transfers...

I use a sabrent rocket v2 and designed a mount for it on the tilta cage, and I can hit every recording spec that you can do over usb on my pocket 6k. I'd recommend grabbing one of those.

Thanks for the tip. Sabrent seems to be a good brand. I went with what was recommended on the site though I am looking at trying the crucial x9 or x10 as well.
