Speed-Comparison: VirtualHere on Raspberry Pi vs Silex DS-600
Due its compatibility and stability I would prefer to use VirtualHere (optimized / licensed) on Raspberry Pi 4 instead using Silex DS-600.
Software on Silex DS-600 is sometimes picky and not quite stable.
However, I made a speed comparison with following results:
Silex DS-600 USB-Server / Transcend 128 GB USB3 Stick: stable 120 MByte / Sec. (1,5 GByte file)
VirtualHere (optimized version / licensed) on Raspberry Pi 4 (USB3-Port) / Transcend 128 GB USB3 Stick: 35-40 MByte / Sec. (1,5 GByte file)
