Hi all, I have an Apple USB-c to USB adapter. I have an M2 SSD in a micro USB case. Up until today, I was getting around 330mb write and 400mb read speeds on it using BlackMagic Disk Bench tool. Now I am getting under 5mb! When i plug it into my old 2012 rMBP I get around 330mb write and 400mb read speed. When I plug another USB3 HDD into the rMB, using the USB-C -USB adapter and same USB cable, I get 65mb/s write and 80mb/s read (which is normal for that drive) I have tried erasing an repartitioning etc, but to no avail - same shocking performance. I have reset PRAM & SMC. Made no difference. Any ideas?
