When traveling, I want to transfer RAW files from my camera (on CFExpress cards) to an external SSD (as a backup).
Due to limited space, I am not taking a laptop with me, but only a tablet.
The following hardware will be used:
CFExpress card: Angelbird AV Pro SE (read: 1,700 MB/s)
CFExpress reader: SanDisk Pro-Reader (USB3.1 Gen2 -> 1,250 MB/s)
Tablet: Lenovo Tab P12 Pro (USB 3.1 -> 625 MB/s)
SSD: SanDisk Extreme Pro Portable (write: 2,000 MB/s)
I now have the following question:
If I use a USB hub on the tablet to connect both the CFx card and the SSD, does the USB-C port on the tablet become a bottleneck because all the data has to flow “through” the tablet first, or does the switching directly take place in the hub?
If there are differences between hubs, how do I find out which hub I have to use to get the highest possible speed (10 Gbit/s, 1,250 MB/s)?
Is there a special designation for the operating modes of such a hub or do I simply have to buy a slightly more expensive hub?
Thanks in advance for your help!
Regards
Johannes
