VMware USB Passthrough speed vs Network data transfer speed

I have a VM running SQL Server with large back ups 100 GB+ ... I need to take a backup of these databases and copy them offsite.

I have a 4TB disk which can hold the backup ...

Which of the following method shall I use for backup transfer considering speed as THE most important factor
a) Connect the USB disk as USB Passthrough device for the VM
b) Transfer the data over network to a Windows Machine and to which the 4TB machine is directly connected

Connect the USB disk to a physical machine on the network or invest in a NAS and VM aware backup application.

USB pass through is slow and its not designed to connect external USB disks.

It was designed for dongles or security tokens.

My advice transfer across the network.

Thanks Andrew

I understand Network is faster than USB Passthrough but how would I take the backup off site using the external USB disk?

I can disconnect the USB disk from VM A
And transfer backup from VM A to VM/PM B
but from VM/PM B ... I have to again connect the USB disk. Only difference is PM will have USB directly attached unlike VM.

Also, how safe is it to use USB passthrough especially for large chunk of data ... would it crash the vm and worse the whole host?

Thanks Andrew.

I have NAS for backups but I just needed these files on an external disk. Will connect the disk to a laptop and attach it to the network and then copy it across.
