Raspberry Pi 4 users, beware! USB device as well as the maximum USB bandwidth available via the UASP protocol. However, it now uses the awful JMicron JMS567 SATA 6 Gb Bridge/s not supporting UASP when connected to a Raspberry Pi In light of this it returns and I will leave the non-UASP case I already have that uses the same chip (Sabrent EC -UASP). This interface is in a shorter cable that works better but still has the same downside as this guardian... it doesn't seem worth keeping it just for that.
