USB3.0 to disks write blocker solution - considering FX3
We are developing an OEM board that can read SATA/eSATA/IDE/USB3.0/USB2.0/SCSI disks' data to PC via USB3.0, but blocking any write operations from PC. I guess this can be done with the following schematics:
[PC] <--(USB3.0)---> FX3<--(GPIF)-->FX3<---(USB3.0)--->USB3.0 Hub<---->Varies bridges<----> [User disk interfaces]
The FX3 chips are connected back-to-back. they block any write operations from PC, while keeping other operations go through.
1. Is this solution feasible?
2. Any better or lower cost solutions possible?
Our team is new to USB3.0. I'll be appreciate for any response.
