DISCONECTS AND ALSO REQUIRE EXTERNAL POWER FOR MAC
THE FACT THAT IT REQUIRES POWERED HUB TO CONNECT TO MACPC IS VERY DSIAPPOINTING. THERE IS NO SPECIAL DRIVER TO REMOVE THATT NEED ALSO. ALSO I HAVE BEEN DISCONNECTED IN THE MIDDLE OF WRITE OR READ OR UNABLE TO FIND DRIVER ALSO. I HAVE BAD EXPERIENCE TO USE IT AS A BAKUP FOR MY LOCAL DRIVE TOO.

Response from Staples :
We're sorry for the inconvenience caused to you. Kindly note that, since this is a high end device, it is important to ensure the host device can supply sufficient power(5 Volts - 3 Amps) at all times during use. Some systems reduce the USB power which may require a third-party powered USB hub, docking station capable of supplying 5 Volts - 3 Amps or more at all times(https://support-en.sandisk.com/app/answers/detailweb/a_id/34968). If you need further assistance or help with product compatibility, please reach us at: https://support-en.sandisk.com/app/askweb.

4TB G40 SSD = Fast & Super Compact External BackUp
Have 15 of these right now, first ones bought at end of June last year.... 14 in pairs, 7 drives duplicated.
Transfer speed is super = a bit less than 100 GB per minute b/w drives via Thunderbolt 3/4 on Mac M1 Studio Ultra.
I do mostly movie stuff right now & will shoot 100-200 GB per day. The SD will say take 20 to 30 minutes to download onto the Mac's 2TB SSD but ...
