Samsung SSD On Sata to USB3 Adapter Cable Shows As SCSI Not USB3
My external Sata Samsung SSD (on a Sata to USB3 adapter cable plugged into a USB3 motherboard external port) shows as a SCSI drive and not as a USB3 drive in Device Manager on my computer. It should show as a USB3 device As a result, the transfer speeds which should operate at 120mbs only operate at 13mbs.
I noticed this as I tried cloning my internal Samsung SSD to an identical external Samsung SSD drive plugged in via that Startech adapter cable. Both drives and the cable worked flawlessly in WIN 7 but not in WIN 10. I called Startech and they indicated it was a known WIN 10 issue on some machines, but had no solutions. Seems like it may be a driver problem and when I access that specific drive/driver it shows a working Windows driver from 2006 with no option to update.
As I said, it operated in WIN 7 properly but not WIN 10. A search showed others with the same issue but no real solution. It takes me over an hour to clone my C drive with WIN 10 whereas it normally takes only 10 minutes with WIN 7.
This desktop computer is a newly built i7-8700k on a MSI Z370 motherboard with a fresh copy of WIN 10 that I purchased. This is my 5th computer build with no issues on WIN XP or WIN 7 previous builds. Had I not decided to do an immediate clone (using Samsung Data Migration as always) I would not have noticed this issue until I tried a large data transfer way down the road. Any thoughts out there?
